Authors: Liu Hongli , Zhao Zixi
Published: March 2023

In the context of prioritizing environmental protection gradually becoming a general trend, how to achieve a balance between paying carbon tax and seeking government subsidies for cold chain logistics service supply chain members to further reduce carbon dioxide emissions of products will be an important decision faced by CCLSP. Based on the influence of the government's carbon tax on the cold chain logistics service supply chain, this paper analyzes the influence of different government subsidy policies on the carbon emission reduction decisions of cold chain logistics service providers (CCLSP), logistics information integrators (LSI) and the supply chain as a whole under the two scenarios of joint emission reduction and independent emission reduction. The effects of different subsidy methods and subsidy rates on carbon emission reduction, wholesale price, retail price and profit of CCLSP and LSI were explored, and the results were analyzed by numerical simulation. The results show that: in the case of joint emission reduction, emission reduction subsidy has a more positive impact on supply chain emission reduction and profit. In the case of independent emission reduction, both subsidy methods have a positive impact on the wholesale price, retail price and the profit of CCLSP and LSI. Which method is more effective needs to be selected according to the size of subsidy rate. To a certain extent, this paper provides opinions for the government to formulate a scientific and reasonable subsidy policy, which can provide a basis for CCLSP to reduce carbon emissions for inquiries.

High entropy strategy on thermoelectric materials
Authors: Dong Jinfeng , Yan Qingyu
Published: March 2023

High-entropy materials, which consist of multiple elements occupying a single sublattice in a disordered manner, have emerged as innovative material systems with various promising applications. Many macroscopic physical properties, such as electrical transport and thermal transport, are closely related to the periodic distribution of atoms. In high-entropy compounds, the long-range periodic arrangement of atoms is broken down by the disordered distribution of various elements, which would lead to changes in physical properties. Therefore, the high-entropy idea will open new avenues for designing these functional materials with promising performance and high reliability. This perspective focuses on the high-entropy strategies of thermoelectric materials, discussing how high entropy will alter their properties. The possible routes of designing high-entropy high-performance thermoelectric materials are prospected, which can also provide enlightenment for the development of high-entropy systems in other research fields.

COVID-19 Pandemic Impact on Copper Futures Prices
Authors: Zhou Jingxuan
Published: March 2023

The COVID-19 pandemic has halted the global economy, causing significant changes in the economic policies of various countries, which have had a significant impact on the relationship between supply and demand for various commodities. Under these circumstances, commodity prices have fluctuated significantly. This paper concentrates on the influence of the COVID-19 pandemic on copper prices to forecast the long-term movement of copper futures prices and provide investment conditions for transacting copper futures contracts. Comparing the timing of different monetary policy announcements in the United States with the trend of copper futures prices reveals a negative correlation between the copper futures prices and the Fed's rate. Moreover, copper storage is susceptible to logistical disruptions, and copper's financial properties have outweighed its industrial properties during monetary policy changes, resulting in a volatile downward trend in copper futures prices in the short term. Copper's industrial properties will be the primary contributor to stable monetary policy and economic expansion, resulting in a gradual upward trend in copper futures prices. In conclusion, hedging investors can profit from long copper futures when quantitative easing is announced, as future copper prices are anticipated to rise. Conversely, speculating investors can profit from long copper futures immediately after the contractionary monetary policy has been announced, as copper futures prices at that time are predicted to be at a trough and rebound shortly.

The Long-term Impact of Covid-19 on Game Industry: Evidence from Daily New Confirmed Cases
Authors: Ying Wending
Published: March 2023

In early 2020, the Covid-19 outbreak caused turmoil in global financial markets, and among the many industries that suffered severely, the gaming industry stood alone, instead growing explosively in the early stages of the outbreak. However, there was a plunge after 2021. This study evaluates how the pandemic has affected gaming markets in China and other international locations. In order to examine changes in the gaming sector in terms of ROE and volatility, a VAR model and an ARMA-GARCH model are built. This study discovers that unexpected epidemic outbreaks have a mainly beneficial influence on the ROE of the gaming sector, but that this advantage gradually diminishes over time as the normal epidemic eventually lessens investor worry. In the environment of a regular epidemic, investor panic is no longer as severe and the impact on gaming industry yields is quantitatively insignificant. Therefore, investors should invest rationally in this sector.
The Response and Results of Countries to the Fed's Rate Hike
Authors: Zheng Haoran
Published: March 2023

Many financial institutions including Europe and Japan remained healthy during the global financial crisis, with deposits guaranteed by the federal government. The surge in demand for money did not have any destabilizing effects on the banking system. In fact, bank deposits also increased during this period. However, the rise in demand for money did cause some problems for the paper money distribution business. Traditional models of money demand suggest that interest rate cuts and federal stimulus payments to households have played a role in explaining the increase in money holdings. This study estimates that these factors account for only about 20% of the observed increase in currency holdings. The rest of the rise was likely due to increased precautionary holdings by people worried about the liquidity or solvency of financial institutions and as a contingency measure. It is in line with the disproportionate increase in demand for large-denomination. These results shed light on guiding further exploration of interest rates.

Published: March 2023

With the development of the chemical industry, the traditional chemical enterprise model of relying on high energy consumption and high input has not adapted to the requirements of high-quality development. At present, chemical enterprises have problems such as low product performance, single product and excessive energy consumption. Wanhua Chemical Co., Ltd. is a technology-intensive high-end chemical enterprise, and its high-end chemical products (e.g., MDI) occupy an important position in the world. However, while investigating and analyzing Wanhua Chemical, it is found that the current enterprise also has a large gap compared with the world's top chemical enterprises. This paper uses SWOT strategic analysis and financial analysis compared with BASF to find that Wanhua Chemical has a single product structure, high repayment pressure, and low research expenditure. On this basis, this study provides a suitable development strategy for Wanhua Chemical, aiming to provide a reference implementation path for Chinese chemical companies to go international.

Published: March 2023

Combining theoretical analysis and empirical research, this paper constructs a theoretical framework for the threshold model on the basis of a review and classification of relevant documents, for instance the empirical study on the existence of monetary policy bank credit channels and the study on the micro transmission mechanism of China's monetary policy credit channels. Based on the actual situation in China and the current state of China's enterprise financing policies, financing constraints, and investment efficiency, this article selects the data of listed companies in China from 2015 to 2021, chooses the balanced panel data as the research object, and obtains 8745 samples from 11624 samples via the balanced panel processing. The empirical analysis of descriptive analysis and regression analysis indicates that when the national monetary policy is maintained at a permissive level, the efficiency of SME joint investment portfolios may be considerably enhanced. In the future, the main monetary policy objectives when China is implemented should be scientifically formulated according to the main characteristics of the behaviors of microeconomic subjects in different industries as much as possible, and a differential monetary policy more suitable for "targeted" development should be adopted to maximize the effect of economic policy, so as to effectively promote the rapid and healthy growth and progress of small and medium-sized enterprises and the stable, sustainable and coordinated development of regional economic development.

Published: March 2023

This paper mainly discusses the prospect of the trade war between China and the US, the future trend of china-US economic and trade relations, and extensively analyzes the causes and influences of the trade war from the perspective of case analysis method and comparative analysis method. The trade war triggered by the trade deficit stems from the desire of both countries to maintain their own strength and economic growth, which makes the compromise difficult. In addition to the continued worsening of bilateral ties, a future decoupling of China-US economic and commercial relations will have significant repercussions for China and the United States, as well as the world economy. In order to prevent the decoupling of our China-US trade ties, China and the United States must settle their differences in our US economic and trade relations via more communication and consultation.

The fresh market e-commerce sales model has also seen growth, especially against the backdrop of the COVID-19 epidemic. In this paper, several leading companies in the Chinese fresh produce market will be analyzed, using different fresh produce e-commerce sales models in China as comparative indicators to explore the profitability of different sales models. Overall, the profitability of fresh produce companies depends on the strength of their supply chain and the quality of their upstream supplies. The results show that traditional fresh produce supermarkets have obvious supply chain advantages, relatively strong profitability and long-term investment value. The O2O model has some profitability, but it requires a lot of financial support and are prone to losses. The market size of the community group buying model is huge, but it is still in the market consolidation stage, and there may be huge profit margins when it matures.
The real estate price prediction of US prediction based on multi-factorial linear regression models
Authors: Xu Xiaoyu
Published: March 2023

In every period, housing price prediction has always been a fascinating topic. Fluctuations in housing price are not only relevant to each individual resident but also to the politics and economy of the country. This essence of this research project is the usage of some real influencing factors to predict housing prices. In the Ames Housing dataset from Kaggle.com, five real factors that have a relatively strong correlation with housing prices are the overall material and finish quality, the above ground living area, the size of garage in car capacity, the garage area, and the total basement area. Based on these five real factors, two multiple linear regression models are constructed for predicting residential prices in Ames, Lowa, US. According to the analysis, when two independent variables are closely related, removing one of them does not necessarily reduce the fit of the model significantly, even if both independent variables are closely related to housing price. Therefore, choosing more appropriate variables is very important to increase the fit of the model. These results shed light on guiding further exploration of using more significant variables to find more accurate models to fit actual housing prices.

Stock price prediction plays an important role in finance and economics. In general, a rise and fall in the share price influences the investors’ determinations and spurs the interest of the researchers over the years. The existing forecasting methods make usage of both linear and non-linear algorithms. From the share price fluctuating of NVDA, AMD, and INTC, we adopted the model MLR (multiple linear regression) to forecast the stock trend and find the relatives of the three stocks within the fixed period. Aside from this, correlation analysis was carried out, and several indexes and metrics were applied to evaluate the models. According to the analysis, three models are constructed, and two of them are relatively significant after improving. Overall, these results shed light on guiding further explorations of stock price forecasting based on the state-of-art financial and statistical models in the concept of big data analysis.

Has the Establishment of FSSC Reduced Inefficient Corporate Investment? --A Test Based on a Two-way Fixed Effects Model
Authors: Ye Yuxin
Published: March 2023

The digital economy has become increasingly prominent as the pillar of the national economy. Meanwhile Financial Shared Service Centre (FSSC), as an important integrated application of digital technology, has been gradually promoted by listed enterprises in recent years. Investment decisions, as an important part of corporate capital operations and financial management, have a great impact on the development of enterprises. Using panel data of 147 listed companies from 2010 to 2019, this paper empirically investigates the impact of establishing FSSC on inefficient investment through a two-way fixed effects model based on individuals and time. The study finds that: the current FSSC has not significantly reduced the inefficient investment of enterprises. On the one hand, the lack of investment control function of FSSC has not inhibited over-investment; on the other hand, the information-assistance function of FSSC has significantly reduced the under-investment behaviour of enterprises. This paper argues that the further development of the investment controlling function of the FSSC is the goal of future FSSC construction.

Authors: Zhou Xue
Published: March 2023

This research explores the relationship between generational differences, economic conditions, rural-urban differences, and 5 dimensions of work ethics (self-resilience, morality/ethics, leisure, hard work, and centrality of work). Online questionnaire results from 620 Chinese post-80s, the 90s, and 00s show that age differences bring no significant impact on the work ethics dimensions except for leisure and centrality of work. The younger generations more value their non-work activities than their work. In terms of economic conditions, it has a positive relationship with all the 5 dimensions of work ethics, except for leisure which is the reverse aspect of the others. In terms of rural-urban differences, individuals from rural areas show higher self-reliance and centrality to work, but no significant differences are found in other dimensions.

Under the background of the new era, enterprise business management faces the threat of various change factors, so it is very important to study the risk of enterprise business management. This paper summarizes the factors that affect the risk of enterprise business management through literature analysis, and constructs the index system of enterprise business management risk chain on this basis. Using the interpretative structural model (ISM), the accessibility matrix is calculated and decomposed; then, the cross-influence matrix (MICMAC) model is used to calculate the driving force and dependence of risk indicators, and finally the deep indicators are obtained. The results show that legal policy, macroeconomic environment, social environment and talent structure have strong driving force and low dependence, which are the deep indexes to control business management risk. Based on the ISM-MICMAC method, the key factors affecting business management risk are identified, which provides theoretical support for the effective construction of business management risk chain and points out the direction for subsequent research on business management risk.
