  • 详情 Peer Md&A Risk Disclosure and Analysts’ Earnings Forecast Accuracy: Evidence from China
    In this study, we investigate whether and how risk disclosure in peer firms’ management discussion and analysis (MD&A) influences analyst earnings forecast accuracy. We find that peer MD&A risk disclosure significantly improves forecast accuracy, demonstrating a positive spillover effect. Moreover, the impact of peer MD&A risk disclosure on analysts’ forecast accuracy strengthens with the comparability and reliability of peer firms’ information, while weakens with the disclosure quality of the focal firm. Finally, peer MD&A risk disclosure also reduces stock price crash risk, providing further evidence that it improves information environment of the focal firm.
  • 详情 Beyond Financial Statements: Does Operational Information Disclosure Mitigate Crash Risk?
    Previous studies on the impact of corporate information disclosure on stock price crash risk have largely focused on financial statements. In contrast, China’s unique monthly operating report disclosure system—featuring high frequency and realtime operational data—offers a distinct information channel. Using data from A-share listed firms from 2010 to 2021, we find that monthly operating report disclosures significantly reduce stock price crash risk by alleviating information asymmetry between firms and external stakeholders. The underlying mechanisms involve restraining managerial opportunism and correcting investor expectation biases. Further analysis shows that firms’ official responses to investor inquiries has no significant effect on crash risk once monthly operational disclosures are accounted for, underscoring that the quality of information disclosed is as important as its frequency. The risk-reducing effect is more pronounced among firms with greater business complexity, weaker internal controls, and lower institutional ownership.
  • 详情 A multifactor model using large language models and investor sentiment from photos and news: new evidence from China
    This study introduces an innovative approach for constructing multimodal investor sentiment indices and explores their varying impacts on stock market returns. We employ the RoBERTa model to quantify text-based sentiment, the Google Inception(v3) model for image-based sentiment measurement, and a multimodal semantic correlation fusion model to comprehensively consider the interplay between textual and visual sentiment features. These sentiment indices are further categorised into industry-specific investor sentiment and market-wide investor sentiment, enabling separate analyses of their effects on stock markets. Furthermore, we leverage these indices to build a multifactor stock selection model and timing strategies. Our research findings demonstrate that multimodal sentiment analysis yields superior predictive accuracy. Industry-specific investor sentiment exerts bidirectional positive influences on stock market returns, whereas market-wide investor sentiment indices exhibit unidirectional impacts. Integrating industry-specific investor sentiment into our multifactor stock selection model effectively enhances portfolio returns. Furthermore, combining market-wide investor sentiment with timing strategy optimisation further augments this advantage.
  • 详情 How Do Online Media Affect Cash Dividends? Evidence from China
    Using a comprehensive dataset for Chinese listed companies from 2009 to 2021, we find that online media is negatively associated with cash dividend level, and the proportion of positive news has a negative moderating effect on this relationship. Our results support the "information intermediary" effect and exclude the "external governance" and "market pressure" effects. We further propose that online media weakens the positive relationship between cash dividends and past earnings (rather than the future), indicating that cash dividends contain signals of improvement in past earnings and are replaced by online news. We also find that only firms with more positive news pay dividends that have signaling effects, and there is a synergistic effect between positive news and dividend signal. Additional results show that the effect of online media on dividend policy is more pronounced than traditional media, which has almost no influence. Our main conclusions remain valid after addressing potential endogeneity issues and conducting various robustness tests.
  • 详情 Innovation: Early Leadership and Age Dynamics -Evidence from Chinese SMEs
    This study investigates the impact of early leadership experiences on innovation performance in small and medium-sized enterprises (SMEs) in China. Using Enterprise Survey for Innovation and Entrepreneurship in China (ESIEC) cross-sectional datasets, it examines the mediating role of psychological traits and the moderating effect of age in this relationship. The analysis employs fixed effects models to control for regional and industry-specific unobserved characteristics. Results indicate a significant positive relationship between early leadership experiences and innovation, with psychological traits mediating this relationship strongly in younger entrepreneurs. For older entrepreneurs, early leadership has a more direct and stronger impact on innovation. These findings underscore the importance of early leadership development in education phase and suggest that the influence and pathways evolve with age, offering particular insights into the formation and application of social and human capital in the entrepreneurial journey
  • 详情 Climate Change and the Current Account
    This paper develops an SOE (small open economy) dynamic general equilibrium model to study the impact of climate change on the current account. By calibrating the model to Chinese economy, we find the following results. First, the current account-output ratio improves in the first decade following an increase in global temperature caused by climate change. It then deteriorates in the following next three decades. Second, the overall current account-output ratio dynamics in response to climate change is neither affected by the types and stringency of climate policies, nor by the levels and growth rates of temperature increases. Third, the impact of an increase in temperature from 1.28 ℃ to 1.5 ℃ relative to the pre-industrial periods (1850-1900) on the current account-output ratio is equivalent to that of an approximate 0.14% permanent decline in TFP. Finally, although the current account-output ratio is likely to deteriorate in the first year when temperature increases instantly, it might not be true if the coefficient of relative risk aversion, or interest rate premium is larger, or debt sensitivity to interest rate is smaller.
  • 详情 How and When Does Coopetition Affect Innovation in Industrial Clusters? The Role of Firm Agility and Government Intervention
    While a wide range of managerial practices suggest that coopetition plays a crucial role in advancing firm innovation, how this effect occurs and the boundary conditions remain unclear. The literature revealing the specific mechanisms by which inter-firm coopetition affects firm innovation, including mediating mechanisms and boundary conditions, is still insufficient. By integrating the resource dependence theory and the capability view, this study explores how firm agility links inter-firm coopetition and open innovation within industrial clusters. In addition, based on conceptualizing coopetition as a concept containing three elements (cooperation, constructive conflict, and destructive conflict), this study examines government intervention in industrial clusters as a boundary factor and explores how it affects the relationship between inter-firm coopetition and firm agility. Based on the analysis of a sample of 181 industrial cluster firms in China, the results of this study show that firm agility mediates the relationship between cooperation, constructive conflict, and open innovation, respectively, and that government intervention diminishes both the facilitating effect of constructive conflict on firm agility and the negative effect of destructive conflict on firm agility. The findings contribute to the understanding of how and when coopetition affects open innovation and provide a theoretical basis for firms to utilize coopetition to innovate successfully.
  • 详情 Spatiotemporal Correlation in Stock Liquidity Through Corporate Networks from Information Disclosure Texts
    The healthy operation of the stock market relies on sound liquidity. We utilize the semantic information from disclosure texts of listed companies on the China Science and Technology Innovation Board (STAR Market) to construct a daily corporate network. Through empirical tests and performance analyses of machine learning models, we elucidate the relationship between the similarity of company disclosure text contents and the temporal and spatial correlations of stock liquidity. Our liquidity indicators encompass trading costs, market depth, trading speed, and price impact, recognized across four dimensions. Furthermore, we reveal that the information loss caused by employing Minimum Spanning Tree (MST) topology significantly affects the explanatory power of network topology indicators for stock liquidity, with a more pronounced impact observed at the document level. Subsequently, by establishing a neural network model to predict next-day liquidity indicators, we demonstrate the temporal relationship of stock liquidity. We model a liquidity predicting task and train a daily liquidity prediction model incorporating Graph Convolutional Network (GCN) modules to solve it. Compared to models with the same parameter structure containing only fully connected layers, the GCN prediction model, which leverages company network structure information, exhibits stronger performance and faster convergence. We provide new insights for research on company disclosure and capital market liquidity.
  • 详情 ESG Rating Results and Corporate Total Factor Productivity
    ESG is emerging as a new benchmark for measuring a company's sustainable development capabilities and social impact. As a measure of ESG performance, ESG ratings are increasingly receiving attention from companies, the general public, and government institutions, and are becoming an important reference factor influencing their decision-making. This paper investigates the impact of corporate ESG ratings on Total Factor Productivity (TFP) and its mechanisms of action. Focusing on listed companies in China, we find that higher ESG ratings contribute to improving a company's TFP, and this conclusion remains valid after robustness tests and addressing endogeneity issues. Further exploration into the reasons behind this result reveals that ESG ratings can be seen as a signal that a company sends to the outside world, representing its overall performance. Higher ESG ratings enhance a company's TFP by reducing market financing constraints and obtaining government subsidies. Heterogeneity analysis shows that the positive impact of ESG ratings on TFP is more pronounced for companies with higher levels of attention, reputation, and audit quality. Additionally, we explore whether ESG ratings can serve as a predictive indicator for measuring a company's TFP. This hypothesis was tested using machine learning algorithms, and the results indicate that models incorporating ESG rating indicators significantly improve the accuracy of predicting a company's TFP capabilities.
  • 详情 ESG Rating Divergence and Stock Price Delays: Evidence from China
    This paper examines the impact of ESG rating divergence on stock price delays in the context of the Chinese capital market. We find that ESG rating divergence significantly increases the stock price delays. Mechanism analysis results suggest that ESG rating divergence affects stock price delays by reducing information transparency and firm internal control quality. Heterogeneous analysis results indicate that the impact of ESG rating divergence on stock price delays is more pronounced in high-tech firms and when investor sentiment is high.
