This paper utilizes an ARIMA model to predict the future exchange rate and trade balance of China. The primary data is the monthly average exchange rate of USD/RMB, while China's monthly trade balance serves as auxiliary data. The findings indicate a projected downward trend in the USD/RMB exchange rate, continuing from 2023 to 2024 and stabilizing around 6.7 from 2024 to 2025. This implies a depreciation of the Chinese currency against the US dollar. Additionally, China's trade balance is expected to experience modest growth over the next two years, albeit at a significantly reduced rate compared to previous years. These projections highlight the challenges faced by Chinese exporters and suggest evolving global trade dynamics. The paper discusses policy implications for managing exchange rate fluctuations and sustaining balanced trade relations. It emphasizes the usefulness of the ARIMA model for forecasting exchange rates and trade balances while acknowledging the limitations and potential impact of unforeseen events or policy changes on the outcomes. The study concludes by suggesting avenues for future research to improve the accuracy and robustness of such forecasts, encouraging continued exploration in this dynamic field of study.

In recent years, China has been gradually and progressively promoting the opening of its capital markets to the outside world. In this study, a questionnaire survey and SEM (Structural Equation Modeling) model analysis were used to investigate the mechanisms and outcomes of capital market openness on Chinese investor sentiment based on the Land-Hong Kong Link Policy.The study reveals that following the opening of the capital markets, individual investor sentiment tends to become more rational due to factors such as changes in investor structure and shifts in value investment concepts. In the future, it is recommended that China's capital markets promote basic investment education and enhance the development of financial regulations to progress towards a deeper level of openness.

The COVID-19 pandemic has had a profound impact on the global macroeconomic landscape, social order, and corporate operations. In light of the prevailing trend of economic globalization, the pandemic has significantly affected this process, but it will not deter the progress of economic globalization. The COVID-19 pandemic has not only had a considerable impact on various countries worldwide but has also affected China. To protect the lives and health of our citizens, China has implemented strict containment policies. The pandemic has also had a significant impression on company operations. Our research focuses on two major Chinese real estate companies, "Poly Developments" and "Vanke A." Both companies have publicly available and transparent financial reports that include information on profit figures, profit margins, cash flow, and debt situations. Despite the impact of the COVID-19 pandemic, Vanke witnessed a downward trend in total revenue and cash flow from 2019 to 2021, but a slight recovery was observed in 2022. Vanke displayed stable revenue growth in its development activities and gradually stabilized its profitability. The company also prioritized effective cash flow management and pursued a diversified development strategy, leading to a significant year-on-year increase in investment cash flow. Overall, Vanke exhibited remarkable performance in sustainable strategic planning, collaboration, and operational activities, maintaining its position as an industry leader.

This paper uses provincial-level gasoline retail price data in Canada to study the effect of tax reform on gasoline retail prices. It uses a dynamic difference-in-difference strategy to estimate the dynamic treatment effect of tax reform to see the dynamic changes of treatment effect in post-reform periods. We find that on average, the tax cut tends to be close to or around the full passthrough rate to the gasoline retail price. The treatment effect does not diminish over time and it is immediate after the tax reform. This means that the gasoline tax cut goes directly to consumers, it will work as a great macroeconomic tool in fighting the current inflation. The implications of effective gasoline taxation policy allow governments to adjust the gasoline taxation when needed to fight off inflation knowing that almost full taxation changes would pass down to the retail level. We conducted an additional robustness check to the robustness of our results.

In recent years, the view of economists and issuers of cryptocurrencies has changed a lot, from the original price of cryptocurrencies is unpredictable, to the view that cryptocurrencies are affected by several key factors. Confidence is one of the key factors, and it is thought to be controllable. However, many economists and cryptocurrency issuers have acknowledged that the support for confidence in the cryptocurrency market is complex and volatile. The goal of this paper is to propose ways to stabilize confidence in cryptocurrencies based on these studies. Explicit and implicit policies are one of the important factors affecting cryptocurrencies. The purpose of this article is to illustrate the close connection between cryptocurrencies and information, and to analyze how explicit and implicit policies affect cryptocurrency information and markets. The impact of explicit and implicit policies on the price of cryptocurrencies is unpredictable, but it still has regularity in the impact on the price of cryptocurrencies. This article analyzes several notable cryptocurrency explicit and implicit policy events to illustrate the differences and characteristics between the two types of policies. The influence of explicit policy is not positively correlated with its propaganda intensity in the short term but will be maintained and stable in the long term. Stealth policies tend to show dramatic changes in a short period of time and are highly correlated with popularity. While hidden policies can cause sudden fluctuations, issuers of cryptocurrencies should pay more attention to the effects of explicit policies because they are more durable.

With the increasing debt accumulated by local governments, land finance has become an important issue worth paying attention to in the China’s economy. Based on the political economy literature, this paper selects general public budget expenditure, regional GDP, per Capita GDP, urbanization rate of permanent people, and the development of the secondary industry as independent variables and the dependence on land finance of the local government as dependent variable. Panel data from 22 provincial local governments is collected for empirical research. The empirical results indicate that accelerating urbanization, general public budget expenditure have led to local governments obtaining extra-budgetary land fiscal revenue. The growth of regional GDP and the expansion of the secondary industry will bring revenue to the region, which will help reduce the dependence of local governments on land finance. The political economics research on land finance helps to understand the economic behavior of local governments in China and also contributes to understanding the issue of soft budget constraint.

This paper aims to use an empirical analysis to study and forecast the bilateral trade between the United States of America and the People’s Republic of China in the post-pandemic era. This study was conducted from three perspectives: aggregate demand (import), supply (export), and trading potentials. In sections of import and export analysis, the paper focuses on analyzing the aggregate behavior by households with Schmitt-Groh´e, Uribe, Woodford’s risk-averse demand model in an open economy and the firm production optimization model by Giovanni, Kalemli-Özcan, Silva, and Yildirim. In the analysis of the bilateral trade potentials, a gravity model of trade with one least square regression was applied and subsidized with the test method from Liu. From the study, it was found that the bilateral import and export between the U.S. and China are facing challenges from stringent policies, fragmentation of global value chains, and the residual effects of the pandemic on consumption. Thereby, the trading potential between the U.S. and China is restrained to an intermediate level, which is not beneficial for the robust growth of bilateral trade in the future.

This study delves into the profound impact of behavioral biases on investment decisions and provides valuable insights into methods for counteracting or surmounting these biases. Specifically, it focuses on four prevalent behavioral biases: loss aversion, endowment bias, framing bias, and overconfidence bias, examining how these biases can lead to potential investment mistakes or risks. To mitigate the influence of behavioral biases, the study proposes several strategies. Firstly, it emphasizes the importance of sourcing information from multiple perspectives and cross-referencing data to avoid reliance on biased or limited sources. Objective evaluation of one's skills and knowledge is also highlighted as a crucial step in reducing biases. Leveraging professional advice or feedback can provide an external perspective and help investors make more rational decisions. Furthermore, the study suggests that regular portfolio review and adjustments are essential to address biases and adapt to changing market conditions. Additionally, proactive visualization of potential outcomes can aid in mitigating biases by promoting a more realistic assessment of risk and reward. The study concludes that behavioral biases play a pivotal role in investment decisions. To bolster investment performance and satisfaction, investors are encouraged to comprehend and rectify these biases.
