THE IMPACTS OF CORPORATE GOVERNANCE MECHANISMS AND OWNERSHIP STRUCTURE ON CAPITAL STRUCTURE OF CHINESE DUAL-LISTED COMPANIES

This research aims to assess how the mechanisms of corporate governance and ownership structure affect the capital structures of Chinese dual-listed companies that list their shares in the China A-share market and the Hong Kong market simultaneously from 2003 to 2019. A binary variable of state control firm attribute is introduced to proxy the political connection to the Chinese government. Both the independent director ratio and CEO duality are negatively and significantly associated with the long-term debt ratio. The board size negatively and significantly relates to the short-term debt ratio. Evidence of board members’ avoidance of investors’ pressure to use more debt and escape from debt lenders’ monitoring is observed in this research. Both foreign ownership and state ownership are significantly and negatively associate with the short-term debt ratio, but significantly and positively associate with the long-term debt ratio. Thus, both foreign investors and the Chinese government prefer the companies to achieve rapid growth through the use of more long-term debts. The binary variable of state control firm attribute has a significant positive association with the short-term debt ratio alone. However, evidence of declining use of long-term debt financing due to political connections, such as the issuance of equity, is not observed.

Corporate ESG Performance and Accounting Information Quality

This paper empirically examines the impact of ESG rating performance on the quality of corporate accounting information with 10015 listed companies in China's A-share market from 2012 to 2021.

Shanghai Stock Exchange Composite Index Prediction Using Macro Variables Based on ARIMAX Model

Stock market prediction has always been a prevailing topic among investors and researchers. Among numerous market index, the Shanghai Stock Exchange Composite Index (SSE Index) is recognized as one of the most indicative stock indexes in China's A-share market. As it is discovered that the fluctuations of SSE index and exchange rate (USD/CNY) displays highly similar pattern since the subprime mortgage crisis, this study aims to use macro variables (including exchange rate) to predict the SSE index based on ARIMAX model. The data are collected since 2006 and based on which ARIMA (14,1,4) model is generated. Distinct macro variables are added in this ARIMA model respectively and it concludes that the incorporation of exchange rate with certain lags can significantly increase the fitting degree. Cross validations on different lengths of validation sets are implemented, which shows that the model can make accurate forecast in relatively short term. The result manifests increasing accuracy when incorporating certain explanatory regressive factors, which might provide valuable and enlightening information in short term for researchers or investors.

Predicting stock market trends with self-supervised learning

Predicting stock market trends is the basic daily routine task that investors should perform in the stock trading market. Traditional market trends prediction models are generally based on hand-crafted factors or features, which heavily rely on expensive expertise knowledge. Moreover, it is difficult to discover hidden features contained in the stock time series data, which are otherwise helpful for predicting stock market trends. In this paper, we propose a novel stock market trends prediction framework SMART with a self-supervised stock technical data sequence embedding model S3E. Specifically, the model encodes stock technical data sequences into embeddings, which are further trained with multiple self-supervised auxiliary tasks. With the learned sequence embeddings, we make stock market trends predictions based on an LSTM and a feed-forward neural network. We conduct extensive experiments on China A-Shares market and NASDAQ market to show that our model is highly effective for stock market trends prediction. We further deploy SMART in a leading financial service provider in China and the result demonstrates the effectiveness of the proposed method in real-world applications.

An Analysis of the Validity of the Chinese A-share Market During the 14th Five-year Plan Period

The Efficient Market Hypothesis (EMH), initially formulated and subsequently refined by the renowned American economist Eugene Fama in 1970, classifies markets into three tiers of efficiency: weak, semi-strong, and strong. As the world's second-largest economy, China has assumed an increasingly prominent role on the global stage due to its distinctive socialist framework and the ongoing development and enhancement of its capital market. The 14th Five-Year Plan, a pivotal component of China's social development agenda for 2021-2025, holds immense significance in propelling China's economic progress. In this study, utilizing a time series model, we conduct a comprehensive examination of China's A-share market throughout the current century, scrutinize the overarching context of the 14th Five-Year Plan, assess the efficacy of China's capital market, and propose potential remedies and future outlooks in alignment with the pertinent policies outlined by the Chinese government and the factors contributing to the inefficiencies observed within China's A-share market.

Classification of Cloud Computing Sector Stocks Based on Factor Analysis

The development of China's securities market has been more than 30 years, among which China's A-share market has become one of the largest stock markets in the world, and has a good development trend. Since the new era, the digital economy has become an indispensable part of people's lives. Cloud computing related conceptual stocks have received increasing attention from the capital market since 2019. Therefore, this paper classifies the cloud computing stocks and gives some suggestions to investors. 47 cloud computing stocks were randomly selected and their basic data were downloaded from the RESSET database. Through sorting and constructing, two categories of market indicators and fundamental indicators are selected, with a total of 17 variables. In order to reduce the dimensionality of variables, five common factors were first extracted using Factor Analysis and named as price factor, transaction factor, debt paying factor, growth factor, and profit factor according to their characteristics. Using these five factors to carry out K-means clustering, the selected stocks are divided into mature stocks and ordinary stocks.

Corporate ESG Performance and Shareholding Preference of Institutional Investors

With the widespread recognition of ESG investment concept, institutional investors in China's securities market are paying more and more attention to ESG performance of enterprises. However, different types of institutional investors pay different attention to ESG performance, and their shareholding preferences may be different. This paper takes A-share listed companies from 2018 to 2021 as samples to conduct an empirical study. The results show that: on the whole, institutional investors have an obvious ESG preference in China's A-share market, and corporate ESG performance is significantly positively correlated with institutional shareholding ratio. The research on different types of institutional investors shows that independent institutional investors have more obvious ESG preference for shareholding compared with non-independent institutional investors.

Financial Market Reactions under the Russia-Ukraine Conflict-An Empirical Study Based on a Multi-factor Model

This paper takes advantage of the turbulent situation in eastern Ukraine to study and examine the correlation between war conflicts and stock yields, and to study the impact on the stock returns of A-share listed companies in China. The background of this article is that with the Russian Ministry of Defense announcing the withdrawal of troops stationed on the border between Russia and Ukraine, the crisis situation in eastern Ukraine has been cooling since October 2021, until February 2022, when Ukraine announced in civilian forces that it would evacuate the local population to Russia on the same day, while the situation in eastern Ukraine deteriorated, the local government banned foreign aircraft from entering the country, and declared Ukraine a state of war. This article constructs an index factor that measures the degree of war through the cryptocurrency market price fluctuation index and the cryptocurrency market price fluctuation index. In addition, a new war impact index factor is added to the basic three-factor model, and the explanatory performance of the new multi-factor model for the stock yield of listed companies is more in-depth and whether it is more explanatory than the three-factor model. The study will test whether the Russian-Ukrainian conflict will significantly affect equity returns in China's A-share market. Helps investors better describe the expected returns of a cross-sectional stock portfolio.

M&A goodwill impairment, management ability and firm performance: Empirical evidence from Chinese a-shares

The Chinese capital market created a large amount of goodwill assets after several waves of mergers, acquisitions, and restructuring. The potential risks posed by these goodwill assets to the continued stable development of the business during subsequent impairments cannot be ignored. This study selects a sample of non-financial listed companies in the A-share market in China for 2007–2021. The results indicate that goodwill impairment significantly and negatively affects firm performance. At the same time, goodwill impairment significantly affects management capability and mitigates the impact of goodwill impairment on company performance by exercising management capability. High-capacity management plays a greater inhibiting role in the relationship between goodwill impairment and corporate performance. The findings of this study validate the management's ability to perform in companies with goodwill impairment under the new accounting standards and also provide reference values on how to reduce the risks associated with goodwill impairment.

Momentum effect and contrarian effect in China's A-share market, under registration-based system

This study examines two questions: first, the existence of momentum and contrarian effects on the growth enterprises market (GEM), since the implementation of the registration-based system in China; second, the influence of different cross-sectional characteristics of companies on the two effects. By constructing a momentum effect model with China's A-share market data, and analyzing the impacts of the issuance registration system on momentum and contrarian effects, we find a short-term momentum effect in the A-share market, which weakens until disappearance in the longer term. However, due to the reform, the effect on GEM changed from momentum to contrarian; companies with low market capitalization, low liquid market capitalization, low price-to-book ratio and high turnover rate were found prone to the contrarian effect. Analysis based on the registration system can help government regulators formulate current policies and make constructive recommendations for investors.

Research on the Applicability of Value Investment in China’s A-Share Market

Value investment has been widely respected and applied in the capital market of developed countries, and its effectiveness has also been verified in a large number of practices. However, since it was introduced to China in 1990s, the concept of value investment has been buried for a long time due to the lack of supervision and the backwardness of investment concepts. With the improvement of the market environment, the progress of supervision system and the update of investors’ ideas in recent years, does China’s A-share market have the conditions for value investment? This paper will discuss this problem theoretically and empirically. Firstly, this paper combs the development of value investment theory and expounds the views and propositions of value investment. Secondly, under the guidance of value investment theory, this paper selects the data of CASMR database 2018-2021. In the first stage, five sectors are selected as the low growth and high growth track of value investment by using multi-factor model. In the second stage, using EVA analysis, five leading stocks in each industry are selected for empirical test, combined with the fundamental analysis in each stage. The results show that the average annual rate of return of the top enterprises is over 50% and the average annual rate of return is over 30% in the high-growth industries screened out under the concept of value investment; This paper verifies that value investment is not only suitable for China A-share market, but also an excellent investment idea with low risk and high return, and puts forward some relevant investment suggestions.

Digital transformation and corporate ESG: Evidence from China

With the fast growing of digital technologies, digitalization is becoming a dominant force in corporate operation. This paper examines the impact of digital transformation on corporate environmental, social and corporate governance (ESG). Based on the data of heavy polluters in China's A-share market from 2010- 2021, the study finds that heavy polluters with a high degree of digital transformation have higher ESG levels. Furthermore, there are heterogeneous characteristics of digital transformation to enhance ESG responsibility performance, and in state-owned firms heavy, ESG level is more sensitive to digital transformation.

The Value Effect of ESG Ratings during the COVID-19 - Empirical Evidence from Chinese A-Share Market

Since 2020, the scale of ESG responsible investment in China has developed rapidly, and during the epidemic, the city was affected by the closure of roads. Although it is difficult to influence consumers' choice in the product market in the short term, investors in the stock market can "vote with their feet" in a timely manner, so how do investors perceive the ESG rating of the company? What is their perception of a company's ESG rating? This paper examines the role of ESG ratings in China's A-share market during the crisis, using the Xin Guan epidemic as an entry point, and concludes that (1) ESG ratings are significantly and positively correlated with short-term cumulative stock excess returns, and that company carbon intensity plays a moderating role in ; (2) in the long run, higher ESG ratings reduce stock price volatility; and (3) the epidemic enhances the correlation between ESG ratings and company stock price volatility. correlation level between ESG ratings and company share price volatility.
