This paper conducts a regression analysis using data from Chinese listed companies between 2008 and 2023, and finds the following: First, financial support significantly increases firms’ customer dependence; second, financial support indirectly promotes the enhancement of customer dependence by reducing firms’ excess administrative expenses; third, further heterogeneity analysis reveals that the impact of financial support on customer dependence varies significantly depending on whether the firm is audited by a Big Four accounting firm, with the effect being more pronounced in firms not audited by a Big Four firm.

We study how politicians' activities affect the stock market and firm performance. Using hand-collected data on China's national leaders' corporate visits, we investigate the industry-wide implications of these visits. We find that over the six days surrounding a visit, an average industry peer's value increases by 2\% of its total assets. This result reflects investors' favourable interpretation of leaders' visits as a signal of more government support for the entire industry. However, the industry peer's profitability plummets by more than 15\% in the next three years. Further analysis reveals that after the visits, industry peers increase their investments, presumably in anticipation of additional government subsidies and credits. However, these resources are insufficient, and the profitability of these firms suffers. Our findings suggest that national leaders' visits do not help boost the targeted industries, and firms should carefully interpret the politicians' activities.

企业非效率投资是影响资源配置效率和经济高质量发展的重要因素。已有研究多聚焦于公司治理、外部监管等传统因素对非效率投资的影响，鲜有研究关注行为金融的纠偏是否有助于缓解非效率投资。本文以中国A股上市公司为研究对象，考察人工智能应用所产生的行为金融纠偏对企业非效率投资的影响及其作用机制。研究发现，企业人工智能应用可以显著降低非效率投资程度，在进行了一系列稳健性检验，尤其是控制了公司战略选择这一潜在解释因素后，本文结论依然稳健。机制检验表明，人工智能应用主要通过改善管理层非理性行为缓解企业非效率投资，体现出人工智能技术在认知优化和行为纠偏方面的独特作用。进一步分析未发现人工智能改善公司治理水平的证据，揭示了人工智能应用的边界与局限性。本文丰富和拓展了行为公司金融的研究文献，也为优化提升企业投资效率提供了经验证据。

工商、财务、电子商务都是相辅相成，不是孤立存在的。电商平台的财务管理更加严谨和高效，支付宝从电商财务开始，已演变成全国的金融货币系统。电商财务与数字金融相互促进，共生共荣；两者是“需求驱动创新”与“技术反哺生态”的共生关系。 电商面临的核心财务问题——信任（买卖双方不信任）、效率（资金流转慢）、成本（对账清算复杂）——正是数字金融最初要解决的痛点。 电商财务以业务为导向，与会计分录无关，退款授信主要靠数字证书，而非人为签字！传统财务要财务经理签字、出纳签字、总经理签字，效率极低！

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.

When examining corporate governance in China, it is crucial to recognize the unique socio-economic structures and legal systems at play. The mechanisms of corporate governance theorized in the West might not necessarily have the same impact in China. In particular, given China’s distinct feature of the domestic economy and its socio-political structure, the results of introducing a hostile takeover system might not align with common anticipations that scholars and policymakers in China and elsewhere broadly share. In greater detail, this paper highlights the significant market imperfections in the Chinese economy, stemming from information asymmetry, imperfect product markets, and capital-market inefficiency. These market imperfections suggest that an active hostile takeover regime might not function effectively in China, as its disciplinary mechanism operates successfully in other advanced countries. Additionally, this paper underscores that due to China’s distinctive features—including its state-owned corporate landscape, the dominance of controlling shareholders in private corporations’ ownership structures, and its unique brand of socialism—the introduction of an active takeover regime could produce unintended consequences in the Chinese economy. Overall, challenging the prevailing perspective, I posit that within the Chinese hostile takeover framework, corporate governance is not as influential as one might assume.

We examine whether and how mandatory corporate social responsibility (CSR) disclosures affect corporate tax avoidance. Using a CSR disclosure mandate in China that requires a subset of firms to disclose their CSR activities as an exogenous shock to CSR disclosures, our difference-in-differences analyses show that firms affected by the disclosure mandate engage in less tax avoidance relative to control firms. Additional analyses indicate that increased public scrutiny following the disclosure mandate is the likely channel through which mandatory CSR disclosures constrain tax avoidance. Cross-sectional analyses suggest that the effect of the disclosure mandate varies with institutional environments. Overall, our results indicate that the CSR disclosure mandate constrains corporate tax avoidance, which is consistent with mandatory CSR disclosures nudging firms toward more socially desirable behavior.

We examine the risk-return trade-off in market anomalies within the A-share market, showing that even decaying anomalies may proxy for latent risk factors. To balance forecast bias and variance, we integrate the 1/N and mean-variance frameworks, minimizing out-of-sample forecast error. Treating anomalies as tradable assets, we construct optimized long-short portfolios with strong performance: an average annualized Sharpe ratio of 1.56 and a certainty-equivalent return of 29.4% for a mean-variance investor. These premiums persist post-publication and are largely driven by liquidity risk exposures. Our results remain robust to market frictions, including short-sale constraints and transaction costs. We conclude that even decaying market anomalies may reflect priced risk premia rather than mere mispricing. This research provides practical guidance for academics and investors in return predictability and asset allocation, especially in the unique context of the Chinese A-share market.

The literature has extensively explored the relationship between trade and envi-ronment, with most studies focusing on how trade affects the environment. However, our research takes a different approach by examining how air pollution affects firms’ exports. We use Chinese export and pollution data from 2000 to 2007 at the firm and county levels. By using fine particulate matter (PM2.5) concentrations as a proxy for air pollution and employing thermal inversion as an instrumental variable, we ffnd that a 1% increase in PM2.5 leads to a 0.89% reduction in firms’ exports. We also observe this negative effect of air pollution on entry and exit (i.e., extensive margins). Our mechanism analysis identiffes two channels through which air pollution affects exports. First, air pollution decreases exports by reducing firm productivity. Second, air pollution induces stringent environmental regulations, which reduces exports as firms need to increase abatement costs or reduce production to meet the environment standards.

This study explores how the application of democratic rule in land reform decision-making determines villagers’ political trust towards different levels of the government in China. Based on analyses of a two-period household survey data we find that in China’s most recent Collective Forest Tenure Reform, the use of democratic rule improves villagers’ trust for town and county cadres, whereas the impact on trust towards village cadres is only significant for the democracy involving all the villagers or households in a village. This pattern of trust is partly explained by our findings that the democratic process helped decrease the unresolved inter-village forestland disputes whilst there seems no such impact on the within-village land disputes. Heterogeneity analyses show that democratic decision-making has a more pronounced effect in improving trust for villagers with lower income, and those without affiliation with the Chinese Communist Party (CCP) or to the village committee.
