Published: September 2023

In recent years, with the rapid development of the Internet, the financial market pattern is also changing. And the way of consumption through the Internet is gradually becoming mainstream. In order to meet the needs of the majority of consumers, online credit products have emerged. The emergence of this new financial service is not only a change in the quality of life of the masses of society, but also a new challenge for the financial market. Therefore, this paper investigates its impact on consumers' over-consumption decisions. Through regression analysis, we conclude that there is a positive relationship between the online credit lending model and the public's overspending decision. And the higher the loan amount, the longer the repayment period, the lower the loan interest rate, and the more accessible the loan qualification, the higher the public's willingness to overspend. On the other hand, the degree of loan facilitation has no statistically significant effect on the degree of overspending. By establishing a model to analyze the degree of overspending, this study is conducive to the establishment of reasonable consumption habits by consumers. It can help the financial service industry understand customers' consumption tendencies, rationalize their programs and provide a reference for government agencies to formulate economic policies. And it can promote the successful development of the financial market.

Authors: Xu Jinghan
Published: September 2023

Since the financial crisis, there has been a second phase of global economic divergence. The context for global economic development has been worse due to the anti-globalization tendency and the predominance of trade protectionism. In the face of economic shocks, there are differentiated results for economic resilience among countries. Therefore, it is of great significance to study China's economic vitality against the background of the financial crisis. China's economy shows the negative adjustment effect of ownership structure. The relatively high proportion of state-owned enterprises weakens the promoting effect of economic complexity on regional economic resilience, and the weakening effect is more significant in inland areas. China's accelerated structural reform has increased the complexity of its economy. Therefore, this study focuses on the characteristics of economic resilience during the financial crisis, using China as an example. This paper uses the literature research method, the theoretical analysis method, and the case analysis method. In the context of the financial crisis, China's economic resilience has been fluctuating on an upward trend.

Authors: Beilin Han
Published: September 2023

With the progress of crude oil financialization, crude oil futures has become an important derivative product, and its price discovery function has been widely concerned by investors. The relationship between sentiment and price can be studied by constructing oil market sentiment index. Considering that the investor sentiment of single-market energy futures may not reflect the cross-market impact well, this paper selected OI, PSY, RSI and other commonly used futures trading indicators, and used principal component analysis to construct the investor sentiment indexes of single-market (crude oil) and cross-market (crude oil, fuel oil, coking coal, coke) respectively. VAR, Granger test and linear regression are used to explore the influence of investor sentiment on the volatility of crude oil futures prices. The results show that: (i) There is a Granger causality relationship between single market (crude oil) investor sentiment and crude oil price; (ii) There is no Granger causality relationship between cross-market investor sentiment and crude oil price; (iii) Single market and cross-market investor sentiment have an asymmetric effect on the price fluctuation of crude oil futures market.

Through literature analysis which has revealed that there are six key components to a successful venture capital firm: the team, the syndication, the valuation, the value-add, the interaction with investors, and the exits. Importantly, venture capitalists place more weight on the selection of transactions than on the selection of investments. Rather than considering a company's track record or product offerings, investors will place greater emphasis on the management team behind the venture. Many venture investors subscribe to the old adage that investing in a mediocre idea with excellent management is better than a fantastic business strategy with inexperienced management because a team with competent and experienced employees will play a significant part in the firm's growth. Even while it's crucial to choose your transactions carefully, value can also be created by the addition of new elements after an investment has been made.

This paper collects stock prices, financial data (including P/E ratio, BPS, etc.), risk-free rates, market indices, and other data, and uses multiple linear regression models to predict the return data from January 1st, 2023, to March 10th, 2023. Next, the mean-variance framework is employed for the purpose of selecting both the portfolio with the highest Sharpe ratio and the one with the lowest volatility. Once the weights for both groups are ob-tained, this study tests the portfolio's performance using actual stock price data spanning from January 1st, 2023, to March 10th, 2023. After obtaining the performance data of the two groups, this paper further compares the per-formance of the portfolio with the 1/N portfolio and the market performance. The results show that the market performance is the best, followed by the 1/N portfolio and the minimum volatility portfolio, and the maximum Sharpe ratio model is the worst. This result may provide some guidance for portfolio management for some investors in this special period.

This paper will start with an investigation of the current consumption situation (consumption structure) and the consumption concept of college students at Chongqing University, and investigate the family income, the monthly living expenses of students (whether there is a work study program) and the current loan situation of college students. Based on this problem, this study plans to use the questionnaire and literature survey methods to investigate the income gap of the families behind the college students through the consumption survey. Through the investigation and sorting of consumption, we can see the family income reflected thereby, and compare the gap between the rich and the poor reflected from different angles. This paper further considers the current consumption situation of college students and what consequences the income gap has brought or will bring, as well as the reasons affecting the income gap. At this stage, particular attention should be paid to the issue of urban-rural income disparity and inequality. In the context of Chinas dual economy, household income inequality mainly comes from inequality between urban and rural areas. Effectively improving the income level of rural residents and narrowing the urban-rural gap are the main targets for achieving common prosperity. To achieve common prosperity, first, improve the income distribution system and the macro income distribution structure. Second, increase the income of low-income groups and accelerate the formation of an olive-shaped structure. Third, improve the social security system to alleviate the challenge of excessive income disparities among groups. Fourth, promote the equalization of basic public services in urban and rural areas, and address income inequality. Fifth, increase public investment in human capital and enhance social mobility.

Although the expansion policy shows that Starbucks is still in the stage of growth, from the data of the financial statements in the past 5 years, Starbucks seems to have some problems. This article mainly analyzes the ratio of financial reports related to Starbucks business activities, compares liquidity, profitability data such as ROA, ROE, etc., and further decomposes these data with DuPont analysis. The main purpose of this article is to find out the reasons that caused these changes to analyze the development trends, advantages and problems of Starbucks in the past 5 years. From the analysis, we can see that Starbucks has the advantage of the supply chain system, but there are problems in other respects.
Enhancing Portfolio Performances through LSTM and Covariance Shrinkage
Authors: Li Guangqi
Published: September 2023

Portfolio optimization is a crucial aspect of finance, requiring advanced analytical tools and modeling techniques. This paper proposes a new method for portfolio optimization that combines Long Short-Term Memory (LSTM) forecasting with Covariance Shrinkage and Mean-Variance Optimization (MVO) to construct diversified portfolios that maximize risk-adjusted returns. The study utilizes an LSTM-based model to predict stock prices, evaluating its performance using the RMSE metric. The calculated RMSE of 0.0849 indicates accurate and robust predictions. The portfolio constructed shows different weights each day for different assets based on the minimum variance and maximum Sharpe ratio portfolios. As of January 3rd, 2023, the assets with the largest proportion in the Maximum Sharpe Ratio portfolio and in the Minimum Volatility portfolio, are respectively BA, accounting for 27.64% of the portfolio and PG, accounting for 32.66% of the portfolio. This paper compares the performance of the proposed method and benchmark methods by applying 30 daily portfolio weights to real returns. The portfolio constructed by the proposed method has higher cumulative return with a higher Sharpe ratio and lower maximum drawdown, indicating a better ability to diversify risks and create returns. The proposed method offers a new perspective on portfolio optimization, which can potentially benefit investors and asset managers.

The recent fluctuations in interest rates in the Hong Kong stock market have sparked a significant amount of attention, prompting investors to further intensify their research into portfolio optimization strategies. To determine the most suitable investment plan, this study carefully selected five Hong Kong stocks based on their market capitalization. Predictive data were utilized for portfolio optimization, with the mean-variance analysis framework used to measure portfolio performance. Our model revealed that asset allocation of 2800.HK held the highest proportion in the minimum variance model, with the five stocks holding ratio of 0.119952, 0.000517, 0.067936, 0.030762, and 0.822611 separately. The average cumulative return using mean variance on the testing dataset was 1.091263. The final findings of this study may be useful to investors seeking to optimize their investments in the Hong Kong stock market. The insights gained from this research could help investors make better decisions and achieve improved returns.
The Effects of Population Aging on GDP
Authors: Liu Ruiqi
Published: September 2023

The intensification of population aging affects all aspects of society. Among them, it has a particular impact on economic growth. Some scholars believe that aging will stimulate economic development, while more people believe that aging will burden the economy. Based on research on the five major gross domestic product factors: consumption, investment, government spending, net exports, and the labor market, the aging population brings more harmful effects to the growth of gross domestic production rather than optimistic effects. The aging population only benefits the government expenditure that the government consumes and invests more funds in the aging population. The increasing government expenditure directly raises the gross domestic product. By contrast, the excessive government spending will trigger more critical fiscal problems. Thus, compared with the negative impact on GDP in other areas, the increase in government spending cannot offset those adverse impacts. The government has to take steps to balance the plethora of adverse effects.
