Because of the impact of the COVID-19 pandemic, China's economy and financial markets have been volatile in recent years. This necessitates using financial literacy by Chinese customers to handle their assets effectively and avoid losses. This essay aims to investigate the effect of various demographic parameters on the financial quality of Chinese consumers. The 2019 China Consumer Finance Survey questionnaire yielded 13,000 data points for this article. STATA was applied to screen twelve independent variables associated with financial quality, and a multiple linear regression model was utilized to determine the association between each variable. The findings revealed a strong relationship between age, gender, income, education level, the proportion of household members with sickness, consumer risk preference, rural domicile, family size, self-employment and house ownership with financial quality, except that there was no significant correlation between marital status and consumer financial quality. The results indicated a significant correlation between age, gender, income, education level, and the proportion of household members with illness. These findings imply that different demographic factors influence Chinese consumers' financial quality to varying degrees. As a result, each consumer makes different decisions about managing assets and avoiding risk.

By analysis research on the anchoring effect of previous scholars, it was found that irrational judgments in financial markets due to the anchoring effect are significant with the influence of past information. By analyzing data from the equity and securities markets, we find that even professionals can make inaccurate judgments due to the anchoring effect. In addition, we found that the anchoring effect does not require a significant information factor to be implemented, as different experiments have shown that the subconscious mind can also influence people's decisions. However, it is interesting to note that the anchoring effect can also influence behavior in the opposite way, by limiting the sales of a product and thus increasing the sales of that product.

The paper describes how the COVID-19 pandemic led to a worldwide supply and demand crunch for medical supplies such as masks and Personal protective equipment (PPE), causing a break in the supply chain. The application of circular economy concepts to supply chains creates resilient supply chains by reducing dependence on external inputs and outputs to help business cope with unforeseen disasters. The resilient supply chain is enhanced by applying the "3R" principle of value recapture in the circular economy model, i.e. reduce, reuse and recycle, and also by drawing on economic models such as platform economy and sharing economy. The paper references are taken from academic databases such as Google Scholar, as well as online materials such as official websites and news websites, and publications such as Supply Chain Guide.

The relationship between inflation rate and economic growth has resulted in their correlation becoming a subject in an extensive body of empirical and theoretical studies. Many studies have focused on how inflation relates to positive or negative growth. A gap exists in the threshold value beyond which this correlation works. The study fills this gap by using the threshold model to understand a threshold value beyond which inflation negatively impacts economic growth. The research examines the positive and negative associations between inflation and economic growth, the significant threshold value of the inflation rate beyond which it adversely affects growth, and the variation of threshold value and impact across different countries and economies in different developmental stages. The method involves analyzing secondary sources to establish a theoretical framework on the negative relationship between inflation and economic growth and an empirical framework on the relationship between high and low inflation rates on economic growth and threshold values and their impact on economic growth. The method also involves examining practical examples as a strategy to show that there is a variation in inflation threshold value. The concept of threshold inflation shows that there is a value beyond which an economy of a certain country, irrespective of developmental stage, negatively affects economic growth.

Cryptocurrencies are a new form of currency that have gained widespread attention in today's age of rapid technological advancement. The underlying blockchain technology provides many advantages for cryptocurrency transactions, including decentralization, anonymity, and security. But there are always two sides to a story, and despite the fact that cryptocurrencies have solid technical backing, their development has been severely hampered by issues like the high stability of individual coins and the potential dangers of the technology itself, which have led many nations to pass laws restricting cryptocurrency use. Taking a literature review method, this paper explores the features of cryptocurrencies, their potential for institutionalization as legal tender, and their primary effect on the economy. This paper concludes that the widespread adoption of cryptocurrencies as a viable alternative to fiat currencies is highly improbable in the foreseeable future.

With the advent of the commercial Internet came the birth of the e-commerce industry, and with the proliferation of mobile Internet came the rise of O2O e-commerce. Emerging and quickly entering a phase of vicious competition in terms of subsidies is China's O2O local lifestyle service industry. This thesis takes the O2O e-commerce model of the local life service industry as its research object, uses the revised O2O value system model to analyze the Meituan O2O e-commerce model in depth, and compares it to Ubereats, a typical representative of the C2C business model, in order to identify the problems and put forward corresponding development suggestions, using the basic theories of marketing management, management, and e-commerce. Meituan's success can be attributed in large part to the company's innovative business model, which has given the company a leg up in the market and contributed to the company's distinctive core competitiveness. This paper's findings have important implications for the evolution of the e-commerce sector in the Internet age, the development of new business models for corporations, and the modernization of entire industries.

Reflections upon the acuteness of human intuitive decisions have spurred explorations of interest in behavioral heuristics. While the field has successfully rationalized unexpected outcomes in dissonance against the standard expected utility framework, the path to which its seeming intangibilities make utilitarian contributions toward behaviors and interactions within economies is still yet to be endeavored. Such studies received particularly little attention in China, where awareness of systematic behavioral biases remains limited to the majority of the public, hindering the efficiency of the country’s efforts toward economic development. This dissertation reviews the education system of China, an imperative mechanism, yielding millions whose capabilities and propensities define the prosperity of the world ahead. Through personal experience, a hypothesis was formed around hyperbolic preferences, cognitive dissonance, and the decoy effect. Combining the rigors of survey and the humanistic nature of ethnography, primary research was conducted with students from a district key high school in Shanghai. Results evidently showed students’ tendencies to overvalue one-dimensional test scores while overlooking the potential for un-materialized skills, as well as their nonperformance of creative or critical abilities. Meanwhile, the uprise of international options (AP, IB, A-level, etc.) induced even higher levels of dependence on local education amongst non-international students, as a result of asymmetric information, deepening their oblivion to potential misjudgments due to cognitive bias.

Bitcoin is a peer-to-peer form of digital currency proposed in 2008. Unlike other currencies, Bitcoin does not rely on a specific institution to issue it, it is based on a specific algorithm that generates it through a large number of calculations. In some countries, government agencies, central banks and academia regard Bitcoin is a virtual currency rather than a currency. This is because of Bitcoin’s high volatility, which does not have the two basic functions of the unit of account and the store of value that are unique to the currency. In recent years, Bitcoin has seen increasing media coverage and other cryptocurrency portfolios, as well as the significant capital gains have been seen in the high volatility environment. In this paper, we shed light on the low correlation of Bitcoin with traditional investment assets, making Bitcoin a potentially high-quality source of portfolio diversification. The results of the finding suggest that Bitcoin investments offer significant diversification benefits and should be included in optimal portfolios. In addition to this, we find that hedging strategies involving gold, oil, stocks and Bitcoin significantly reduce portfolio risk.

In recent years, momentum trading has been a very mainstream trading strategy. The Chinese market is an emerging market and there are a large number of retail investors.

These characteristics are favorable for applying the momentum strategy, which has not been widely used in the Chinese market. In this paper, three tests to examine the non-effectiveness and trend correlation of the market are conducted and a momentum strategy - determining the timing of trades by judging the market trend based on those tests is proposed. The empirical experiments shows that when time interval is small, the strategy achieves good performance on two representative indices of Chinese market, the CSI 300 Index and the CSI 500 Index. It also indicates that in certain cases there are indeed a certain of market inefficiency in China and that momentum is a proper trading strategy to get profit.

The strategic choices made by the government and enterprises, as the main participants in environmental governance, decide the direction of environmental governance. Meanwhile, the strategic choices of enterprises will also change the strategic layout of the government. Therefore, current research mainly focuses on what impact the government has on enterprises when it participates in the game, and how will the interested parties make optimal decisions. In this paper, from the perspective of the evolutionary game theory, the strategic choices of the interaction between pollutant-discharging enterprises and between local governments and pollutant-discharging enterprises are discussed; the model of the evolutionary game between pollutant-discharging enterprises and local governments is also built. According to the replicated dynamic equation, the evolutionarily stable strategy of the participants is obtained. The research results indicate that: the higher the return on pollution control is for an enterprise, the more inclined it will be towards pollution control and environmental protection. Environmental governance should reduce the expected benefits of enterprises without treatment of pollutants and should require local governments to strictly implement environmental protection policies, perform their duty, and identify and punish violators in a timely manner.

Since the establishment of the Shanghai Stock Exchange and Shenzhen Stock, stock investment in China has gradually flourished in the past 20 years. When the figure of the stock market rises or falls, it has always affected the state of mind of every investor. For the Chinese stock market, the Shanghai Composite Index and the Shenzhen Component Index are equally important, which is helpful for us to understand the trend of the stock market in depth. However, most studies nowadays only focus on the influence of one index and ignore the essentials of the other, which could lead to a misjudgment by investors. because both indexes have a close correlation with the stock return. so it is necessary to compare the influence of the two indexes on stock returns at the same time. and base on this, I will compare the degree of correlation between the Shanghai index as well as the Shenzhen index on Ningde Times stock returns.

The stock market, often known as the secondary market, is a venue for the transfer, purchase, sale, and circulation of stocks for listed firms and investors. There is a subtle relationship between the stock and the market, and market external factors influence the price of the stock. Thus, variations in stock prices can impact the profits of investors. Hence, the stock of Pfizer is the subject of this research. By analyzing the influence of the NASDAQ and DJLA on Pfizer stock prices. Determine the link between the two indices and the stock returns of Pfizer. Utilizing the Capital asset pricing model (CAPM) through regression analysis of the model and systematic Beta risk data constitutes the research methodology. The conclusion of the investigation is that the index influences the predicted portfolio return for investors. The relevance of this research is to demonstrate that investors can utilize the CAPM asset pricing model to evaluate portfolio returns. In addition, it explains the limitations and benefits of utilizing CAPM based on Pfizer stock data and provides investors with a reference for future usage of the modeling.

Thanks to the rapid development of e-commerce and online shopping, a large amount of shopping basket data has been accumulated. How to mine the useful information in shopping cart data to predict customers' next purchase is an important problem in commercial data analysis, which is widely used in the fields of online advertising and product recommendation. In this paper, three prediction methods are proposed, including frequency-based prediction, rule-based prediction and similarity-based prediction. Moreover, evaluations and analysis of these three methods are conducted on the public dataset. It is found that the items that were frequently purchased by consumers in the past are more likely to continue to be purchased due of the higher prediction accuracy of the frequency-based methods. On the other hand, similarity-based item prediction methods also yielded good results because there is also a significant overlap in the items that similar users want to purchase. Therefore, it is concluded that in practical applications, frequency and similarity-based prediction methods can be applied to predict consumers' next purchases.

The supply chain is an important tool for any economic individual to obtain sustainable development and maintain core competitiveness, and it is also the guarantee of coordinating supply and demand in economic development and financial goods market transactions. Under the new situation of global economic development, most enterprises use more effi-cient and perfect processes to make their supply chain run efficiently in order to maintain competitiveness. On the basis of their respective divisions of labor, different enterprises have formed a pattern of mutual dependence, connection, and common development. The traditional competition among individual enterprises has gradually evolved into a compe-tition among different components of the supply chain. On the basis of perfect economic market, the supply chain further integrates various economic subjects and their activities in series, and refines the individual and overall layout in the economic cycle. This paper fo-cuses on the importance and role of supply chains in the new global economic development situation, specifically on how supply chains can promote and improve the development of economies, enterprises, and individuals. As well as the important coordination and promo-tion role of the supply chain in the whole market's resource processing and circulation in the process of economic development, the relevant research is carried out by means of inves-tigation, data collection, and consultation. After a series of studies, we have come to the conclusion that the supply chain plays an irreplaceable role and has significant significance in economic development and enterprise development in the global market and plays an important coordinating and helping role in the development of different industries.

When it comes to the revitalization of the countryside, talents are inevitably needed. Talent revitalization can achieve the development of the countryside. Similarly, the revitalization of the countryside can also attract talents. The two are complementary to each other. However, at present, the countryside of Hainan Province is relatively backward, and most of the imported talents are concentrated in the cities and towns. This paper takes the backward villages in Hainan Province as the research objects, and studies the current situation of rural talents in the city in detail through a literature review, data analysis, field survey, and interview, searching for the existing problems. According to the survey, Hainan Province currently suffers from a shortage of talents, an imperfect talent training mechanism, insufficient attraction of foreign talents, and a weak management ability of village cadres. Meanwhile, countermeasures such as improving the talent training system, exploring and attracting talents in all aspects, and providing employment and entrepreneurial opportunities are proposed. The development of the countryside still needs to focus on the leading industries of Hainan Province, cultivate local talents, attract foreign talents, and make efforts to improve the quality of the talent team.

The emergence and wide application of behavioral finance explain the problems that can-not be explained by traditional financial concepts and provides people with a new way of thinking. This paper mainly reviews the literature on overconfidence in behavioral fi-nance. The purpose is to quickly help people who have little contact with overconfidence and help them understand the main contents of overconfidence (progress, advantages, dis-advantages, application). And then judge whether they have overconfidence. If it exists, how do use overconfidence for self-benefit instead of making mistakes? At the same time, the literature summarizes the application of overconfidence and possible future research directions. There are two important research directions. One is to integrate the two modes of rational investors and irrational investors or to develop the dual mode of coexistence of rational and irrational investors. The second is to use behavioral finance to conduct asset pricing or change the theoretical assumptions that traditional financial models are incon-sistent with behavioral finance. Then, we discuss and analyze it in many aspects of behav-ioral finance. So that different people can make better judgments under different circum-stances.
