When the night is no longer lit up by stars, when the light that man once craved gradually swallows up the world, light pollution leaves the night sky without its back- ground, and life on the blue planet is immersed in the pain of light invasion. How to measure and solve light pollution has become an urgent global problem in today’s world, and we are deeply worried about it. So, we built an indicator model and developed effective methods to improve light pollution. For TASK I : In order to enhance the wide applicability of our model, we established TOPSIS Method based on AHP Model and Entropy Weight Method, which was used to analyze the indirect factors reﬂecting light pollution to the degree of regional pollution and their respective proportions. It is showed on the results that the regional vehicle ownership is the indirect factor reﬂecting the greatest degree of light pollution. After that, we deeply analyzed the more speciﬁc factors reﬂecting the impact of light pollution on the area by establishing a random forest model. Finally, we learned that biodiversity was the most important factor reﬂecting the impact of light pollution, accounting for 37% among the factors we consider. For TASK II: In order to control the inﬂuencing factors, light intensity and color temperature were divided into four levels as ﬁrst-level factors, and the inﬂuence of artiﬁcial light was taken as second-level factors. Satellite images were simulated and optimal interval method and linear regression model were used to establish the contribution model of light pollution. Through this model, we proposed three intervention strategies and evaluated each of the four regions. The results showed that the scheme using lampshades worked best in suburban and urban communities, reducing light pollution risk levels by about 52 percent. For TASK III: We selected the most effective strategies for improving light pollution in Shanghai and produced a leaﬂet at last.

Regional Carbon Emissions and Downstream and Upstream Supply Chain Decisions for Firms
Authors: Qiao Baisen
Published: April 2023

The supply chain is essential for comprehending the financial behavior and decision-making of firms. Under the macro trend of reducing carbon emissions, there is a close connection between regional carbon emissions and corporate supply chain decisions. However, there exist few researches on the relationship between "regional carbon emissions" and "downstream and upstream supply chain concentration of firms". In view of this, this paper empirically analyses the impact of regional carbon emissions on the decision of downstream and upstream concentrations of firms, using the panel statistics of A-share listed firms in Shenzhen and Shanghai between 2008 and 2020 as the research samples. The findings show that regional carbon emissions have a significant heterogeneous impact on the downstream and upstream supply chain decisions of firms, reducing the upstream concentration of firms but strengthening the downstream concentration of firms. The mechanism analysis illustrates that regional carbon emissions decrease upstream supply chain concentration by forcing local firms to increase green innovation and weaken corporate governance and increase downstream supply chain concentration by raising the financial constraints of local firms. This paper not only enriches the field of research on influencing factors in corporate supply chain decision-making but also serves as a reference for the construction of green supply chains in the background of carbon neutrality, thus having significant practical implications as well as policy implications.

The influence of non-controlling major shareholder's exit threat on firm's idiosyncratic risk
Authors: Wang Rongxuan , Huang Yankai , Feng Teng
Published: April 2023

Non-controlling major shareholders can effectively restrain controlling shareholders and management by exit threat, so as to participate in corporate governance. Traditional research holds that the exit threat of non-controlling major shareholders can make the company have a more stable development prospect, but it has not paid enough attention to the hidden dangers. Based on 23,243 samples of Shanghai and Shenzhen A-shares from 2010 to 2021, this paper analyzes the influence of non-controlling major shareholder's exit threat on idiosyncratic risk of enterprises. It is found that the exit threat of non-controlling major shareholders will significantly increase the idiosyncratic risk of enterprises. Overall, exit threat lead to increased idiosyncratic risk. This conclusion is still robust after controlling for endogenous problems. The reason why the exit threat amplifies the idiosyncratic risk is that the idiosyncratic volatility is the market's response to the increased uncertainty of the future return rate of individual stocks, while the high exit threat of non-controlling major shareholders of a company exposes the future uncertainty of the company to investors more. This paper reveals that the threat of exit is the key factor affecting the idiosyncratic risk of firms, which has important reference value for regulators and investors.

Authors: Yu Qianting
Published: April 2023

One of the most significant societal occurrences of the twenty-first century is the COVID-19 epidemic, which still affects many people around the world today, from all developing to developed countries. This paper connects the COVID-19 epidemic to German sociologist Ulrich Beck's theory of risk society. This research is beneficial to the management of future epidemics. This paper examines COVID-19's manufacturing and distribution, management and influence using a case study methodology based on Beck's theory. This research found the COVID-19 pandemic can infect any person, eliminating the boundaries of social inequality. But the COVID-19 pandemic has also widened the boundaries of inequality, because in developing countries or regions, people's vaccination rates are low. Meanwhile, vulnerable groups such as the poor or the elderly are not adequately protected and have a greater risk of being infected. So it is important to take action at the global level and pay greater attention to vulnerable groups.

The Impact of COVID-19 on Employment Ratio: Evidence from U.S and China
Authors: Dong Luke
Published: April 2023

With the increase in number of infected people worldwide, the impact of COVID-19 on the world has become increasingly severe. In this article, the data collected during the 2020s is used in order to investigate the impact of COVID-19 on the employment rate and analyze its reason using two distinct samples. To be specific, data from China and the US is selected to act as evidence to support the claim in the study. In addition, this research carried out some comparisons between the two cases. According to the analysis, the results have shown that both China has lost about 80 million jobs during the start of the pandemic and the US having about 14% job losses during the first season of 2022. If one looks at the huge population base, which both have an extremely high negative employment rate and most of the jobs are travel or service or capital construction related. However, as time gradually goes by China has recovered faster than the US, gaining most of the job loss back. Even though China’s economy is mainly based on the worker level, but since its quick and positive attitude in stopping the pandemic from spreading further its economics recovered soon. Nevertheless, since the US’s main economic body isn’t produced by workers, the attempt of raising the employment rate back to before seems not that much of a priority. These results shed light on guiding further exploration of policy implantation during pandemic.

Authors: Du Ningxin
Published: April 2023

Since March 16, 2022, when the first federal funds rate hike was announced, federal funds rate has been raised from 0.25% to a level between 0.25% and 0.5%. Until July 27, 2022, the Fed has raised federal funds rate four times, bringing the benchmark of federal funds rate from 0.25% to a range of 2.25% to 2.5%. Against the backdrop of a downward spiral in the US economy and increased inflationary pressure, monetary policy in the US is gradually tightening. This paper selects two typical cryptocurrencies, Bitcoin and Ethereum, and uses time-series model to analyze the impact of US dollar appreciation on cryptocurrency market under the background of Fed rate hike, to fill the research gap and make suggestions for investors and policymakers. This paper concludes that US dollar appreciation would not affect Bitcoin market significantly but would negatively affect Ethereum market. Investors are supposed to be more alert to the risks of cryptocurrency market and reduce the holdings of Ethereum when US dollar index increases. For policymakers, they are suggested to increase regulation of cryptocurrency markets and prevent some malicious speculators’ attacks on the unmatured market from happening.
The economics impact of COVID-19 has been greater for women than men
Authors: Jia Xinyi
Published: April 2023

The COVID-19 pandemic has caused profound economic, social and health shocks globally, affecting men and women differently. On an economic level, the COVID-19 crisis has created an unprecedented unemployment crisis. Therefore, it is crucial to tackle with the negative influences of the COVID-19 through research that identifies questions and proposes measures to address them. The main research topic of this essay is to explore the economic impact of the pandemic on the male and female labor force. It mainly involves three aspects, namely the unemployment rate of men and women after the epidemic, the number of men and women who fell into extreme poverty after the epidemic, and the ratio of men and women in the industries hardest hit by the epidemic. This essay will use the direct method to collect the corresponding quantitative data and analyze the data, which is constructed from the analysis results. Thus, the crucial finding of this report is that the pandemic has hit women the hardest economically than men. A generalization of the data results reveals that women are overrepresented in hard-hit industries, explaining their relatively greater employment loss (economic loss) compared to men. The final recommendations of this report are based on discussion and analysis that governments and organizations should develop employment policies that promote gender equality, especially labor market policies that effectively address gender issues, and support the creation of full and productive employment for women and men.

Authors: Li Yue
Published: April 2023

In the rapid development of modern society, microfinance companies are an inevitable product of the economic market demand, and microfinance companies are bound by the relevant laws of China and enjoy the policy support of the state. As an effective supplement to traditional banking financial institutions, microfinance companies, with their flexible mechanisms and efficient services, are increasingly becoming an important force in achieving the goal of financial inclusion. However, due to the lack of supervision, shortage of capital, and excessive risks, microfinance companies have also been deviating from the original purpose of inclusive financial services, such as "non-farming" and "centralization" of loans. The emergence of the Grameen Bank in the 19th century - a "bank for the poor" - broke the original concept. It will be the case study for analysis in this paper. Using the case of Grameen Bank, this paper aims to explore the characteristics and advantages of small lending institutions, analyze whether they are replicable, sustainable and the social significance their existence brings, and make recommendations and prospects for promoting a greater role of microfinance companies in financial inclusion.
