This paper is targeted at the policies and adjustments of the United States against the nuclear program of Iran during the administration of Donald Trump and Joe Biden and attempts to analyze the reasons and motivations. After the Trump administration took office, the United States unilaterally withdrew from the Joint Comprehensive Plan of Action (JCPOA) and implemented an all-round suppression of Iran. On the contrary, President Biden has shown a strong willingness to rejoin the deal and released goodwill to Iran frequently. Biden’s policy seems to be significantly different from that of Trump, but it does not deviate from the framework of the Trump administration. This paper explores the foreign policies of the two governments towards Iran through three levels of analysis and uses cognitive psychology to analyze the influence of Trump's personal factors on his policies. It concludes that Trump's policies on Iran nuclear issue during his administration are mainly affected by his political personality and national security environment, while Biden's strategic adjustment to the foreign policy is more influenced by political pressure at home and abroad besides national security.

In response to the aging population, China has proposed a new family planning policy, the "three-child policy." On May 31, 2021, the Decision on Optimizing the Fertility Policy to Promote Long-term Balanced Population Development pointed out that China's fertility policy should be further optimized, which included that a couple can have three children. On July 20th, 2021, “the Decision of the Central Committee of the Communist Party of China and the State Council on Optimizing the Fertility Policy to Promote Long-term Balanced Population Development” was announced. On July 21, the "Notice of the Office of the National Medical and Social Security Bureau on Doing a Good Job in Supporting the three-Child Policy and Maternity Insurance” was announced. On August 20, 2021, the Standing Committee of the National People's Congress passed a decision on the revision of “the Population and Family Planning Law”. The revised law advocates marriage of the right age, good prenatal and postnatal care, and that a couple can have three children. However, it is a great challenge to women, so whether this policy can be effectively improved and implemented will depend on the current social and political development situation. This paper will analyze the "three-child policy" from both advantages and disadvantages to predict its impact. This is beneficial because it can reduce the aging of the population and promote social and economic development. The disadvantages are the harm to women, physical influence, psychological pressure and social tolerance towards women, and whether the company will reject female employees.

The phenomenon of Asia-African relations has received considerable attention since the start of the 21st century. As China and Japan are two leading Asian donors of Africa, their foreign aid policies are worth analyzing and comparing. Among African countries, Ethiopia is located in the horn of Africa, whose strategic position is relatively significant. In addition, Ethiopia has not been colonized in the history, which makes this case more meaningful. Most of the previous studies have concentrated on either one specific aspect like economic or certain country’s foreign aid policies towards Ethiopia. This research aims to analyze and compare China’s and Japan’s multifaceted foreign aid policies towards Africa and Ethiopia in particular. For this purpose, the primary data and materials have been collected from the official websites, official reports, and previous studies. The result shows that their differences involve political, economic and societal aspects. The Japanese government has tended to design detailed policies, guide companies to invest in Ethiopia and cooperate with the NGOs. On the contrary, China’s policies towards Ethiopia are more general, and the Chinese government has played a leading role in economic aiding than the Japanese government. In terms of the societal aspect, the Chinese government is more tending to cooperate with the Ethiopian government instead of the NGOs.

With the development of Internet technology and the application of big data, the collection, dissemination and use of information become more convenient, people's private lives become more transparent, and concerns about information disclosure or illegal treatment of personal information also follow. By using the methods of literature analysis and comparative analysis, this paper tries to improve the legal protection mechanism of personal information in China by studying the latest legislation in Europe and the United States, and combining the national conditions and actual situation in China. Although the CCPA of the United States and the GDPR of the European Union have great reference significance, they should also pay attention to the potential problems existing in these two legislations, demonstrate the applicability of their practices with an objective and critical view, and formulate a personal information protection legal system with strong applicability that is suitable for China's national conditions.

With the development of market economy and modern science and technology, some listed companies' financial frauds are constantly discovered and exposed. Taking Zoneco as a case, combining with fraud triangle theory, this paper analyzes the background, causes and means of financial fraud in enterprises, which is different from the traditional way of combining financial statement data analysis with on-the-spot inventory. This paper discusses that modern big data technology provides a more innovative and intuitive method for identifying fraud, and broadens the way for maintaining the stability for the securities market.

Project Portfolio Management (PPM) is a subsidiary of project management. It is used to control and coordinate the projects in various organizations' portfolios with clear objectives of maximizing the project results, balancing portfolio threats, and aligning the projects to meet the business's strategic aims. In many organizations, PPM is ranked on a higher level than the project management concept because the goal of PPM is to achieve the strategic objectives of an organization. However, risks typically arise during project implementation and management. The project managers constantly work to minimize the project risks while simultaneously maximizing the intended values of a given project. The project management teams should manage the risks while achieving the strategic goals and objectives of an organization. This paper discusses the relationship between PPM and risk management during the project implementation process. The paper explored the use of a systematic literature review to come up with these critical findings. The author recommends that there's a need to use empirical data to validate the existing theories and published literature findings. The project Portfolio Risk Management (PPRM) has practical and theoretical approaches in risk management (RM), decision theory, and modern portfolio theory. The use of a systematic literature review approach was used in the execution of this study to gain more insights into the influence of risks on project portfolio and success, identification of the project portfolio risks, and the management of risks in the project portfolio management context.

When people think of Hong Kong in the 1960s, most will recall the industrialized prosperity of Hong Kong. Most scholars regard the industrialized prosperity in the 1960s as a direct consequence of the U.S Embargo Policy launched in the 1950s, during the Korean War. However, a no less important driving force, the impacts of the dynamic role of local businessmen and local chambers on the growth of industries has been overlooked. Given the current academic neglect of the local dynamic role, this paper aims to analyze the driving force played by local actors such as associations, chambers of commerce, and even merchants in promoting Hong Kong’s industrial growth, especially in the shipping industries. This paper will demonstrate the effect of embargo policy as well as the contribution of local dynamics, which altogether provides a comprehensive understanding of the factors affecting Hong Kong’s industrial growth in the 1950s.

Gender equality has been a global debate both within the political, social and business environment. Gender equality according to most researchers have established a positive relationship with performance of organization. Furthermore, in relation to the impact gender equality has on business strategy execution, it would be argued that having gender equality enhances effective execution of business strategies. The study seeks to find out the gender impact on the execution of business strategy. This would include conducing a survey suing questionnaires from 50 women.

With the expansion of China cosmetic market, many cosmetic groups are engaging in expend their market share. However, the development of cosmetics led to diversified consumers’ needs. Some of customers want to get more skincare products for sensitive skin meanwhile the others care about makeup products' characteristics. Various demands have led to the constant updating of the development strategies of the cosmetic groups. Through reading the literature and research reports on Chinese cosmetics in recent years, it is found that the Chinese cosmetics market is oligopolistic and L’Oreal is the biggest one in several big international groups. However, the rise of domestic cosmetic brands makes these big international groups feel threatened. Domestic brands have a better understanding on physiological and psychological needs of Chinese, even Asian consumers, which make them have the strong competitiveness. In the paper, 4Ps model and Porter’s five forces model are used to analyze the current situation of the cosmetics market and the competitiveness of L 'Oreal Group. Finally, some implications are demonstrated from the perspective of culture, brand introduction, optimization of advertising structure, and consumers’ demands to help L’Oreal improve its competitiveness.

With the normalization of the epidemic in the United States, the COVID-19 virus is increasingly regarded as a more contagious "big flu" with higher-fatality. The new coronavirus has mutated to make it more susceptible to multiple infections, and some patients may experience symptoms that last for months or years. Unlike previous direct economic crises, the COVID-19 epidemic has played a negative role in the transmission of economic policies in the process of economic recovery, reducing the pertinence of economic policies and the speed of full resumption of work and production. Given the accumulation of negative issues caused by economic policies in the U.S. since the epidemic, this article will discuss the current state of the U.S. industrial economy, high inflation and Fed policy, as well as the international environment and cooperation.

As a major engine of the capital market, the stock market is favored by investors. But the huge profit space and operability are also easy to breed the soil of corruption and fraud. At present, due to the increased participation efficiency of short-selling institutions, the financial risks faced by enterprises have further increased. Through the case of Luckin coffee, we observe the stock price changes after it encountered short selling, combined with the model of the arbitrage pricing principle to find the role of short-selling institutions in the market. By disclosing corporate financial fraud, short-sellers can improve the effectiveness of market supervision to a certain extent, reduce the occurrence of stock market premiums, and bring stock prices back to their true levels. On the premise of ensuring the stability of the stock market and introducing a reasonable system, the Chinese market can also consider developing a similar mechanism to inject fresh blood into economic development.

The financial structure of a firm is often regarded as the most essential factor influencing its operating performance. The real estate industry, as an important part of China's current national economy, is a typical capital-intensive industry with a large demand for capital. However, the industry's characteristics lead to a relatively slow return of capital in the real estate industry, putting pressure on the industry's financing capacity and capital structure. This paper divides the capital structure into two components: gearing ratio and debt structure, and takes China's real estate listed companies from 2010 to 2020 as a sample. The influence of capital structure on the performance of listed companies is examined empirically. It is found that there is a non-linear relationship between gearing and firm performance, i.e. an inverted U-shaped relationship. This paper still holds after robustness tests such as variable substitution, which are hoped to be useful for business performance, future government regulation and policy implementation.

The establishment of the cross-Straits common Market was first proposed at the beginning of this century and has repeatedly appeared in official government documents. So far, however, progress on the common market has been slow. Therefore, this paper mainly studies the restricting factors of cross-strait common market. This paper first analyzes the status of the common market in the process of economic cooperation. Then it analyzes the current situation of cross-strait cooperation through trade, investment, industrial layout and Preferential Taiwan policies. Finally, we find that political opposition, structural contradiction and political opposition are the restrictive factors for the establishment of cross-Straits common market.

This paper contributes to the modern neoliberal institutionalist line of thinking and international relations studies by revisiting and discussing neoliberal arguments under today’s socio-economic and political background. The goal is to defend neoliberal institutionalism through a brief and yet systematic review of classical neoliberal works. An interdisciplinary approach is taken through paralleling neoliberalism with theories in philosophy (utilitarianism and pragmatism) and politics. Criticisms from neorealists and worrying issues like state-contestation and counter-institutionalization are discussed and defended. Afghanistan’s accession to becoming a WTO member has been used as an example to show the positive influence that international organizations and institutions can exert in the 21st century.

With the rapid growth of urban residents' private cars, the problem of parking in the old communities has become increasingly prominent. Taking the T Community in the Qinhuai District of Nanjing as an example, this paper analyzes the current situation and problems of residential parking through an on-the-spot investigation. This paper uses questionnaires and interviews to analyze the parking needs of residents, and proposes a parking problem governance strategy, in order to provide a reference for alleviating the parking problem in the community. Key recommendations include excavating the parking space inside the community, expanding parking resources by rectifying road resources and sharing parking at different times and peaks, and optimizing management measures of community parking.

In the age of advanced digital technology, the traditional medical industry is gradually expanding its Inter-net medical business. Internet hospitals are gradually coming to the public. Internet Healthcare refers to a new type of medical and health service industry that uses the Internet and information technology to collaborate with traditional healthcare. Its main functions include remote diagnosis, online e-prescription, online medicine purchase, home delivery of medicines, medical condition tracking, patient electronic medical record formation management and disease management, etc. Because the Internet hospital is still in the initial stage of development, many functions are not available, and many relevant regulations are not detailed enough. However, the covid-19 outbreak has to some extent driven the sudden progress of Internet hospitals. This article analyzes the progress and breakthroughs made by Internet hospitals during the outbreak and the development prospects of Internet hospitals in the post-pandemic era in a macroscopic manner through known data and reports. In addition, this article analyzes the problems that Internet hospitals may encounter, and more importantly, this article will suggest corresponding solutions. Ultimately, this article concludes that Internet hospitals have good prospects for development, which will not be possible without technological breakthroughs, government policy support, user perceptions, and Internet hospitals’ innovation.

Since 2020, the outbreak of COVID-19 has had a huge impact on the global economy. In fact, as early as the outbreak of the financial crisis in 2008, it has deeply revealed the complexity of the macroeconomic system, the systemic importance of the financial sector and its high sensitivity to economic exogenous shocks. As an important part of the financial market, bond has a very important impact on the current economic development. Through the study of the current world economy, this paper finds that the epidemic is an unexpected event that changes the world power, the world pattern and the world economic relations, and will bring a profound impact on the world economy. Perhaps the most important change, pre - and post-pandemic, is that the challenges facing humanity will be even greater. The economic growth of developed economies is also unstable due to the impact of the epidemic. The growth of developing countries and emerging economies is more unstable, the risk of inflation and deflation will alternate, and the debt and financial risks are increasing. The risk of supply chain restructuring and supply chain relinking will alternate. A bond market is a place where the government can raise funds in a credit way to balance fiscal revenues and expenditures, which can play a role in promoting economic development. However, the excessive development of the bond market has a negative impact on economic growth and even poses a threat to economic stability. In this regard, this paper puts forward suggestions from the government, enterprise decision-makers and investors to promote the healthy development of the economy.

As one of the most frequently-taken measures to combat the COVID-19 viral spread, the lockdown policy had always been questioned with its impacts on the stock markets and accessibility in the long run. In this paper, I examine the respective stock closing prices of FTSE.GI and 0.000001SH in the UK and China, the countries that had announced lockdown policies several times to find out whether the lockdown restrictions and relaxations negatively affected the investors and their performance in the stock market. By analyzing the stock data with economic theories, it is found that although the markets did show positive returns in the final phases of declarations, they went through low liquidity, high volatility and negative returns for the majority time. Furthermore, the results also suggest that because of the presence of economic inertia and negative investor sentiment, further lockdown had adversely impacted the stock markets, indicating that the alternant lockdown announcements (restriction and relaxation) are not the best long-term solution to COVID from a stock market perspective.

It took only four years for China to transform CBDC research and development into pilot projects. Among the countries engaged in CBDC research, China may have made the fastest progress in CBDC research and development. However, the current research focuses mainly on mechanism and the design of e-cny and its geopolitical implications, and does not answer the question why the people's Bank of China became the first major country to implement CBDC. To answer these questions, this paper analyzes the institutional foundations from a macro strategic perspective that have allowed China and the PBoC to lead the world in testing CBDC. Then this paper analyzes China’s CBDC development process with a focus on the role of China’s financial regulatory institutions and policy innovation. It identifies the key agencies and key decision makers in the process of China’s CDBC research and development process. It also provides a comparative analysis of China’s institutional feature vis-à-vis the United States to further illustrate China’s institutional settings for it to be the first to launch CBDC.

This analysis focuses on the economic theory and the data presented for both economic growth and inequality from 1960 to 2020 in China by examining the influence of economic growth and development on Chinese economic inequality. The purpose of this research is to find the relationship between economic growth and inequality by determining the negative correlation and examining both negative and positive aspects of economic growth and its relationship to living standards.

Due to the special status of the United States and the U.S. dollar in the world economy, the U.S. monetary policy has a significant spillover effect on the world. Especially since the subprime mortgage crisis in 2007, the U.S. monetary policy has attracted more attention from the world. Combined with the previous literature, this paper finds that the transmission channels of the US monetary policy uncertainty spillover effect include exchange rate expectation channel, financial asset allocation channel, contagion of monetary policy uncertainty, and real option effect. Among them, the channel of exchange rate expectations, the channel of financial asset allocation and the channel of contagion of monetary policy uncertainty are responsive and rapid, while the real option effect has a slow and long-term impact on the real economy. At the same time, there are differences in the spillover effects of U.S. monetary policy uncertainty on different countries. The results of this study have certain guiding significance for monetary policy formulation in other countries, such as strengthening the supervision of cross-border bonds and cross-border investment. Especially under the impact of the new crown pneumonia epidemic, major developed economies have implemented a new round of quantitative easing monetary policies, and policymakers in emerging economies need to pay great attention to this.

The derivatives market is widely recognized in financial markets, and it has developed rapidly, but there is little evidence that it contributed to the development of financial and economic markets. This article investigates the dynamic relationship between the Indian derivatives market and the stock market to determine how it affects market pricing. This paper use the DCC-garCH model to examine the dynamics of India from the third quarter of 2018 to 2022, I find that the financial derivatives market is more financially contagious than the equity market. Therefore, I can analyse that the development of derivatives has a positive impact on economic growth.

Companies worldwide create mission, vision, and values (MVV) statements to center their objectives, guide employees' behaviors and increase revenues. As more movement for societal reform takes place, companies started to emphasize diversity, equity, and inclusion (DEI) in their workplaces, and DEI has become an increasingly important factor for employee recruiting. In theory, MVV statements and DEI improvements should increase company performance as they push for more effective employee behavior and intellectual collaboration. This paper partially assess the truth of this theory by determining if Fortune 1000 companies' publicity of their MVV statements and DEI strategies correlate with their status as Fortune 500. Specifically, whether companies' mentioning of their MVV statements and DEI strategies on their website—where customers, employees, and potential employees obtain information about the company—correlate with their rankings on Fortune 1000. Through the aforementioned analysis, this paper found that Fortune 500 companies are more likely to include vision and values statements and possess a longer vision statement and more company values on their websites. This means it may be beneficial for companies looking to increase their revenues to include vision statements around length 8, the median vision statement length for the sampled Fortune 500 companies, and include around 4 company values, the median number of company values for the sampled Fortune 500 companies. Referencing the contents of this paper may assist companies seeking to improve their income.

The way many industries function is changing as a result of the advancement of artificial intelligence technology. Under the influence of the digital revolution, the financial industry has seen significant changes and advancements. This paper will explore some specific impacts on the financial data industry from the role of AI in modern society and the expansion of various industries. It is mainly used to explore whether AI really plays an irreplaceable role in the field of finance and related data, as well as its advantages and disadvantages. Through the practical application of AI-related technology, as well as the reflection of the industry being used by people today, the importance of AI is explored by some examples. AI's role in today's world, especially in related fields such as finance, is undoubtedly very important, but there are still many risks that people need to pay attention to.

Recent Chinese cases of the copyright disputes on AI-generated content (AGC) reveal challenges to copyright jurisprudence by Natural Language Processing (NPL)-based AI systems. Some scholars argued from the perspectives of intellectual characteristics of the AGC. This paper, however, combines historical and doctrinal methods to show that the production process of AGC should be the defining factor of work. This paper argues that modern copyright law does not protect the AI-generated content from the aspect of copyright law in intellectual writings/ paintings/ music/ art as ‘work’. ‘Work’ in the history of copyright law requires direct human intellectual labor, which the AI lacks. AI does not have physical and / or mental labor to the levels of humans, and the human physical and intellectual labors put into building the AI system is different from the AI’s production of contents. These are two separate and consecutive processes: humans make AI, and AI automatically generates contents. The second process cannot produce work because it does not involve comparable labor to humans.

The inauguration of Samia Suluhu Hassan as Tanzania's first female president in March 2021 caught the world's attention. Since the highest political positions are typically dominated by men, the career life of a new female president could be instructional for achieving gender parity in political participation. Previous Academic literature has studied women in power from different perspectives, including the upbring environment, personal characteristics, and special social context. In this article, I examine Samia's electoral success in the 2010 election, which was a major milestone on her path to becoming president, as it brought her to key positions in the Tanzanian government and the ruling party. I argue that Samia Suluhu's electoral success is largely due to her personal charisma and attributes, the encouraging international and domestic social context for women, as well as local politics and civil unrest in Zanzibar, which instigated a social consensus for the need for a new leadership style that Samia offered.

Due to the continuous development of China's economy and society, the ownership of new energy vehicles will continue to rise steadily. At the same time, people begin to pay more attention to environmental pollution, and consumers' willingness to buy new energy vehicles is also strengthening. The development of a new generation of new energy vehicles in China can promote the transformation and upgrading of China's automobile industry, speed up the technological revolution, and reduce energy consumption and environmental pollution. In order to discuss the current China's new energy vehicle how to gain more market share, this paper explores the new marketing model of China's new energy vehicles, the prospect of behavioral economics model, the heavy anchor effect, mental accounts, by using field investigation, respectively from the macro environment, China's new energy vehicle depot. Based on the comprehensive analysis of the current situation and consumer psychology, taking Xiaopeng Automobile as an example, this paper proposes that the market share can be improved by issuing time-effective coupons for car purchase, improving the brand's good first impression and regularly organizing incentive activities with high consumer participation which will provide a reference for the development of other companies in the automotive industry and open up new ideas to promote the development of new energy vehicles in China.

With the rapid development of the Internet era, the consumption demand, form and mode of online consumers are constantly updated. Live commerce for selling products continues to open new channels for product sales mode through major social platforms. Tiktok is one of the most popular social short video platforms in contemporary times. Tiktok live broadcast brings new and intuitive consumption mode and immersive shopping experience to users and consumers.

The purpose and significance of this paper is to understand the improvement, contribution and future development space of Tiktok live commerce and delivery in all aspects, also aims to understand the origin and future development of the live streaming industry, and bring a reference to people in this industry or interested in this platform.

COVID-19 has been a global pandemic since 2019. It has put a mask on the world. How to effectively reduce the spread and ravages has become a worldwide problem. China, as a developing country with a large population, has managed to control the outbreak of the virus effectively. In this paper, the research question is how China effectively controlled the spread of the virus from the initial stage of epidemic prevention to the current policy situation. The development and changes of China's epidemic prevention policy were discussed from the perspectives of time and space dimensions. In general, the dynamic zero policy is the most suitable epidemic prevention policy for China at present. It is expected that this study can provide some enlightenment for the development of China's health system and provide some reference for the epidemic prevention measures of other countries in the world.

The instability and large-scale cyclical fluctuation of China's live pig prices have had a great impact on the whole live pig industry chain. In 2016, the Chinese government launched the to promote the development of the live pig futures market as an effective means to restrain prices and avoid risks, while reducing the cost pressure of pork demanders such as pork processors. This paper will start with the concept of futures and hedging, and analyze how relevant enterprises use futures hedging to avoid the risk of price reduction through China's lower live pig market, as well as how the whole market benefits.

With the acceleration of the pace of life, the attraction of traditional store marketing methods to customers is gradually weakening. Consumers need a new consumption experience model, and the flash business model came into being. This paper mainly refers to the basic theories of flash store and visual marketing when studying the differences between flash store visual marketing and conventional stores, and analyzes the actual performance of flash store visual marketing according to the corresponding brand cases. After the brand positioning is determined, the target customers are also described in detail. Combined with the relevant theories of the flash store, the defects in the design of the brand flash store are solved in practice, and some research results are obtained. This paper hopes to deepen consumers' understanding of flash stores through the study of flash stores, so as to promote the better development of flash stores.

This paper investigates how the lexical richness of a corporation’s annual financial reports connects with earnings management (EM) in all industry sectors (except industries with different accounting methods, such as Utilities and Financial services) and in North America only. In order to explore the above-mentioned relationship, this study introduces new variables – Type-token proportion (TTR). Utilizing the TTR and the square root of TTR (denoted as Unique Index in this paper) to quantify the lexical extravagance of the management discussion and analysis section of the annual report (MD&A), this paper anticipates and finds that firms probably going to have manipulated their earnings to beat the previous year’s benchmark and have MD&As with high-level writing proficiency (a kind of complexity). This is coherent with the conclusion of Lo et al.’s paper: good news is inherently easier to communicate, and suggests that words of choice help complicate disclosure and conceal bad news.

The freight transportation industry experienced an increasingly significant role in the global market. In particular, road transportation continued developing over the years with the development of technology. On the other hand, the emergence of Covid-19 facilitated the digitalization speed of road transportation. Hence, this paper identified the application of AI and data science techniques, particularly in the land transportation area within the freight transportation industry. The article first introduced the site's current situation from the sides of development and Covid-19 disease. Then, the author compared data science and AI techniques with traditional approaches. Finally, the present application and future technology trends are identified for the future trend prediction.

Discuss whether the gradual popularization of digital currencies will have any impact on Internet finance. When digital currencies slowly enter our lives, the way we trade will gradually change, which will have a subtle impact on us. This paper through the literature induction method, found that not only digital currency will affect the development of Internet finance, but also affect the development of traditional commercial banks, through the study of the structure of Internet finance and the theory of digital currency, this paper can be inferred The emergence of digital currencies and how their gradual popularization will affect Internet finance, and through observation and summary, digital currencies have gradually penetrated into people's trading methods, and the issuance of digital currencies will bring many positive impacts to Internet finance. For example, the settlement method of digital currency will reduce the transaction costs of Internet finance, and the issuance of digital currency may lead to the rise of interest rates, making people more inclined to become investors, enter the Internet financial market for investment and purchase derivatives, thereby promoting currency circulation and promoting international economic development. Therefore, the issuance of digital currency is conducive to the development of a country's Internet finance, which can bring many benefits to Internet finance, so that the economy can be further developed and technology can progress.

Dunhuang was a trading forefront along the ancient Silk Road and a hub for cultural interchange and integration. As the world's largest and best-preserved repository of Buddhist art, the Mo Kao Grotto at Dunhuang contains many valuable materials that reflect the mix of multiple cultures. This paper takes the "Li Ning x Dunhuang Museum Ta Series" co-branded new products launch as an example. Applying the communication theory of cultural symbols, two parts of 4R Marketing Theory and the theory of two-step flow of communication, this paper explores marketing strategies for commercializing cultural heritage IP in the new media environment. The purpose is to study how cultural heritage should be utilized for its profound cultural and artistic connotations to cooperate with brands ingeniously in cross-border business. This study finds that the unique historical connotations of cultural heritage can enhance consumers' cultural identity, thus enhancing user stickiness, expanding brand awareness, attracting potential consumers and promoting its own cultural values at the same time.

The new coronavirus epidemic has brought great obstacles to China's economic development. Faced with the impact of the epidemic, the Chinese government has used fiscal and monetary policies to accelerate economic recovery. This paper, through a method of literature review, explores the impact of COVID-19 on China's economy and economic recovery under policy support. The paper finds that the outbreak of the new coronavirus disease has had a significant impact on China's economy and financial markets but also brought great pressure to China's enterprise financing. In an environment of weak domestic and foreign demand and increased international environmental uncertainty, the outbreak of the new coronavirus has intensified the pressure of the economic downturn and added new uncertainty to economic development. Many people's income levels have declined. Apparel, shoes and hats, gold and silver jewelry industry consumption fell sharply. The epidemic has a great impact on the consumption part of the economy, so it is a good choice to develop an economy based on exports. With the help of fiscal policy, monetary policy, and stimulus measures, China's exports have grown rapidly and PPI levels have risen, making it the most foreign-attractive country in emerging economies.

Previous studies have shown that higher heights can bring greater happiness for human being. Although most scholars agree that height will affect people's happiness through material factors such as higher income and a higher success rate in the mate selection market. Not all scholars believe that the influence of height on happiness can be explained by these material factors. This paper aims to study whether height will have a positive impact on happiness for the elderly when relevant material factors are diluted. The author uses CGSS data in 2017 to establish an OLS regression model and comes to the conclusion that height has a positive impact on the happiness of the elderly, and finds that this impact is more significant for men than for women. The author excluded the possibility that this effect was caused by the accumulation of material in the past by adding interactive regression to the model. At the end of the article, the author looks forward to further clarifying the mechanism behind this influence.

This article is a study on the security of decentralized finance. We summarize the background and application of decentralized finance, as well as the development history and latest research of decentralized finance. Moreover, we propose a classification framework for existing various DeFi DApps. We also manually collected attacks against decentralized financial applications and classified them by category. Through some case studies, we give some best practices for practitioners in decentralized finance industries to avoid or defend against attacks.

Research in risk preference suggests that, in violation of economic man hypothesis, most investors are economically irrational, which is reflected through the phenomenon of preference reversal. However, there is a scant of study to measure the extent how irrational individuals are. Inspired by the way how efficient market is defined, this paper proposes a measurement of preference reversal and divides irrationality into two types. Furthermore, based on the data of market index and GARCH-M model, this paper finds that risk preference inconsistency always exists and investors in smooth time are weakly irrational.

Undoubtedly, the concept of the business cycle has become a crucial topic of research, given that the business cycle reflects a nation's economic development and that assessing the business cycle lays the groundwork for a nation to introduce a diverse array of economic policies. This research study aims to evaluate Singapore's business cycles from 1971 to 2021, a span of 41 years. The yearly real GDP and several of its components (private consumption, gross fixed capital formation, and government consumption spending), and CPI were filtered utilizing the Hodrick-Prescott method. Taking the cyclical components of real GDP as the reference cycle and other economic indicators as specific cycles, the author assessed and measured the fluctuations and co-movements between them with the application of standard deviation and correlation coefficient. Last, a few policy suggestions are proposed. There are five main conclusions in this article: (1) Singapore's real GDP is highly susceptible to changes in the international environment; (2) Private consumption, investment, and CPI have a positive and significant correlation with GDP, and investment is of greater relevance to economic growth in the short run; (3) Government expenditure and GDP are negatively correlated; (4) Private investment appears to be a possible cause of business cycle shocks due to the most dramatic fluctuation; and (5) The government of Singapore should encourage private investment so as to boost economic prosperity in the short term, and then promote private consumption to achieve national prosperity in the long run.

Since price is one of the most important parts of economics and the market, there are a lot of articles that have done more research on the topic of price. And the price of rubber varies all the time all over the world. There are many cases showed a significantly decreasing or increasing in the price of rubber, rubber is also a typical raw material in the world. The question is what are the reasons of the change in rubber prices? One method is available that is using different economics principles from microeconomics and macroeconomics to illustrate this question in three aspects.

Mostly factors in the market changed will have impacts on the value of price.

This paper reviews the past research on option pricing, including the Bachelier option pricing formula, Black-Scholes model, and the Cox-Ross-Rubinstein (CRR) binomial option pricing model. Then some practical calculations are performed on the Black-Scholes model and CRR binomial model and the differences between the results of these two models are analyzed for investors to choose the appropriate model for option prices. From the practical calculation results, it is verified that the Black-Scholes model can give out the analytical solutions of option prices and decrease the calculation of solution, while it can only be used for European options with stock prices regarded as a continuous process. For the CRR binomial model, although it can only give numerical solutions and requires lots of calculation because of too many branches, but it can solve the American option prices with early exercises and the European option prices with stock prices regarded as a discrete process.

High-quality patents have high technical value and market competitive advantage. Faced with the huge number of patent data, how to rapidly and efficiently identify the quality of patents from the patent announcement is a crucial research issue at present. Therefore, it is reasonable to predict that, big data based techniques will be the best method to exploit this kind of data. The patents authorized by CNIPA (China National Intellectual Property Administration) are taken as the research object. This study chooses several types of patent evaluation indicators and uses EWM (The Entropy Weight Method) to calculate the weight of each indicator. The study determines a correction coefficient to enhance the usability and provides the final quality score of each patent. The evaluating formula is provided. In this study, easily accessible patent indicators are used, which makes it easier to evaluate the quality of patents. By this method, rapidly evaluating the patent quality only by its basic announcement data is feasible, which solves the limitation that laborious access to advanced indicators.

As climate change has become increasingly complex in recent decades, it has been listed as a top global risk. Not only does it have an impact on the climate, such as the increase in severe weather, and global warming, but also has a corresponding impact on enterprises, becoming a hard constraint on their economic development. This paper mainly studies how climate change affects the sustainable development management of Chinese enterprises. Besides, the paper also aims to explore how Chinese companies can adjust their sustainable development management policies under climate change. In addition, it mainly analyses the impact of climate change on its enterprises through literature analysis and case studies. Through the research, it is found that under the influence of climate change, Chinese enterprises are still lacking in sustainable development management and their strategies are not flexible enough. And they must make up for their shortcomings from the practices of large international enterprises or organizations.

Our research seeks to determine whether the detection of potential fraud in China-listed U.S. companies could be measured by the U.S. M-Score and F-Score models. Then, we group the data for 18 pairs of companies to make a t-test defined as the average difference between firms' M-scores or F-scores before and after the fraud. Moreover, more detailed information about these companies, financial fraud methods and motives, and ways to prevent financial fraud. Through our preliminary research, these two U.S. detection models can be used to detect financial fraud for Chinese-listed U.S. companies in statistical significance. With this premise, we also do an additional t-test to prove the standing adverse effects of committing fraud on firms.

The sudden COVID-19 outbreak in 2019 has had a huge impact on all walks of life around the world. Schools, shopping malls, companies and sporting events have closed or gone bankrupt. This study will focus on the impact of COVID-19 on the future development of the sports event industry. In this regard, we divided the overall impact into three perspectives to analyze: 1. We first analyzed the data of many major international sports events affected by the COVID-19 epidemic. We compared the financial data of event organizers before and after the pandemic and analyzed their revenue changes. 2. At the same time, we also studied the impact on sponsors of sports events before and after the pandemic. We used data from the Olympic Games over the years and sports events like the NBA to do the analysis. 3. Finally, we analyzed typical sports industry companies to study their financial statements and revenue changes before and after the pandemic, such as NIKE. In addition, we also conducted research on the surrounding industries of sports events, such as supplies for sports events, players' jerseys, energy drinks and so on. Broadcasters are also the subject of our analysis. We analyze the target events they broadcast and the ratings of broadcast events. Our findings suggest that the impact of COVID-19 on sporting events has been mixed: the good thing is that it has boosted new events, such as esports. Esports is an all-in-one format, and even offline events are staged on an electronic screen. So esports has emerged as one of the new mainstream events when so many major events have been canceled; The bad news is mainly the impact on the large offline industry, many events are shelved, and sponsors' ads are nowhere to be shown and shown, and sponsors' money is lost. But the pandemic has not caused major sponsors to pull back, just a small number of companies and investors. The significance of this study is to analyze the impact of the pandemic on the future development of sports events, so as to help people identify the current situation and future exit of major sports events, help investors understand the emerging and potential sports events, and help people understand how to mitigate the impact of the pandemic on sports events.
