• 详情 全球强制性ESG披露政策与中国供应商企业气候信息披露——基于中国出口贸易的证据
    气候信息披露对于实现“双碳”目标,促进供应链可持续发展至关重要。本文通过合并中国上市公司和海关数据,基于各国强制性ESG披露政策的自然实验,考察其对中国出口供应商企业气候信息披露的影响。研究发现,出口目的国强制性ESG披露政策对中国出口供应商企业气候信息披露具有增进效应,供应商企业的主动模仿和客户倒逼是重要的实现机制。异质性检验发现,当中国出口供应商为污染型企业、面临较高的外部环境关注度,及目的国强制性ESG披露政策执行更为严格时,政策效果更为显著。进一步分析发现,中国出口供应商企业气候信息披露的完善不仅有助于增加企业对实行强制性ESG披露政策国家的出口,而且能够提升供应商企业未来的经营绩效。本文丰富了气候信息披露影响因素与实现机制的研究,增强了对强制性ESG披露政策的理解,对构建可持续供应链和提升企业国际竞争力具有重要启示。
  • 详情 Early IPO Registration System Reform and Financialization of Real-Sector Enterprises: A Quasi-Natural Experiment Based on the ChiNext Market
    The reform of the IPO registration system is a crucial step toward the maturity, improvement, and marketization of the securities market. In recent years, the trend of corporate financialization has become increasingly evident. Based on data from firms listed on the ChiNext Market and the Main Board, this paper constructs a Propensity Score Matching-Difference-in-Differences (PSM-DID) model and an RDD-DID model to examine the impact of IPO registration system reform on corporate financialization and analyze its underlying mechanisms from multiple perspectives. The estimation results of both models indicate that the IPO registration system reform has significantly increased firms’ financialization levels. Furthermore, a series of robustness checks confirm the reliability of the findings. The mechanism analysis reveals that the reform has promoted corporate financialization by lowering listing thresholds, alleviating financing constraints, and intensifying market competition. Meanwhile, its information disclosure mechanism has to some extent curbed financialization. Further heterogeneity analysis shows that the reform’s promoting effect is more pronounced in non-state-owned enterprises, firms with lower growth potential, and those with weaker corporate social responsibility (CSR) performance. This study enriches the literature on the policy impact of IPO registration system reform, provides a new perspective on how such reforms influence corporate financialization, and offers important implications for curbing excessive financialization in real-sector enterprises, deepening IPO registration system reform, and further improving capital markets.
  • 详情 Decoding the Nexus: Industry Litigation Risks and Corporate Misconduct in the Chinese Market
    This study examines the relationship between industry litigation risk and corporate misconduct using China's A-share listed companies’ data from 2007 to 2022. The findings indicate a significant and negative association, where companies in industries with higher median litigation amounts relative to their assets exhibit reduced incidents of misconduct. This suggests that businesses in high-risk litigation sectors may adopt more cautious practices to mitigate legal challenges and protect their reputations. The robustness of these findings is confirmed through a variety of tests, including a quasi-experimental setting of the chief judges rotation implemented in 2008. Furthermore, the study finds that external monitors including financial analysts’ site visits and local law firms moderate the negative relationship between litigation risk and misconduct. We further show that legal enforcement and moral capital are the two channels through which industry litigation risk impacts corporate misconduct. Our findings underscore the role of litigation risk in shaping peer firms' behavior.
  • 详情 成长的代价: 上市前超额现金分红与上市后长期表现
    本文基于2000-2024年手工收集的IPO公司上市前的现金分红数据,系统考察了上市前现金分红与公司长期市场表现的关系。研究发现,(1)上市前实施高额现金分红的公司,其IPO后长期市场表现显著较差,这一负面效应在成长型公司和融资约束较高的公司中尤为突出;(2)通过构建考虑公司盈利能力、成长性、规模及杠杆水平的超额分红指标,发现超额分红公司的IPO前分红水平与上市后长期表现呈显著负相关,而分红不足公司则呈现微弱的正相关关系;(3)IPO前超额分红行为通过挤占公司资本性支出、降低投资效率等渠道削弱了企业的增长潜力。本研究不仅丰富了公司股利政策的经济后果研究,也为完善新股发行监管制度提供了重要的经验证据。
  • 详情 Animal spirits: Superstitious behavior by mutual fund managers
    Using a unique dataset from China spanning 2005 to 2023, we investigate how superstitious beliefs influence mutual fund managers’ risk-taking behavior and how this influence evolves over their careers. We find a significant 6.82% reduction in risk-taking during managers’ zodiac years, traditionally considered unlucky in Chinese culture. This effect is particularly pronounced among less experienced managers, those without financial education backgrounds, and those with lower management skills. The impact also intensifies during periods of high market volatility. Our findings challenge the traditional dichotomy between retail and professional investors, showing that even professional fund managers can be influenced by irrational beliefs early in their careers. However, the diminishing effect of superstition with experience and expertise suggests a gradual transition towards more rational decision-making. Our results provide insights into the process by which financial professionals evolve from exhibiting behavior akin to retail investors to becoming the rational actors often assumed in financial theory.
  • 详情 Estimating the Term Premium: Sample Periods Matter
    Estimates of canonical affine term structure model parameters are highly sensitive to sample periods. For example, depending on whether the sample starts in 1961 or 1981, the 5-5 forward risk-neutral rate for September 1981 differs by 4.6 percentage points or 98% of the latter. The estimated response of this rate to high-frequency monetary policy shocks differs by a factor of three, even within a fixed sample for the monetary policy transmission regression. We suggest that a shifting endpoint model can mitigate these issues. Additionally, we provide new estimates of the effects of monetary policy shocks on long-term risk-neutral rates.
  • 详情 绿色标准与企业创新——基于大语言模型的指标刻度与绿色金融机制探索
    2019年,国家发布《绿色产业指导目录》,首次明确绿色产业范围和技术标准,旨在为包括绿色金融体系在内经济社会绿色转型中一系列制度安排的重点支持方向提供技术上的参考目录,提高资源配置效率。本文以《目录》提供的技术文本为基础、运用前沿的大语言模型,构建了全新的基于专业技术角度的企业绿色技术指标,避免了传统企业环境效益评价指标(如ESG指标)存在的覆盖不足和漂绿高估问题。以该指标为基础,本文运用双重差分法考察《目录》对企业创新能力、投资行为及经营绩效的影响。实证结果表明,《目录》的颁布鼓励企业加大了研发投入、增加了绿色支出,提升了绿色企业的创新能力,尤其促进了企业的高质量创新产出。进一步地融资机制探索表明,明确绿色标准显著降低了相关企业的融资成本,尤其对企业信贷融资渠道的影响更为显著。最后,本文通过经济意义分析发现,《目录》提高了企业的经营绩效和节能减排。本文的研究结论为进一步健全绿色金融机制、实现绿色可持续发展提供了有益参考。
  • 详情 Does social media make banks more fragile? Evidence from Twitter
    Using a sample of U.S. commercial banks from 2009 to 2022, we find that the flow of non-core deposits, rather than that of core deposits, becomes more sensitive to bank performance as banks receive increased attention on Twitter. This effect is particularly pronounced during periods of poor bank performance, when Twitter discussions are more influential, and for banks with more liquidity mismatch. Our results suggest that social media, rather than merely disseminating information about bank performance, makes depositors aware of their peers’ attention to banks, thereby intensifying the sensitivity of deposit outflows to weak fundamentals.
  • 详情 Sustainable Dynamic Investing with Predictable ESG Information Flows
    This paper proposes the concepts of ESG information flows and a predictable framework of ESG flows based on AR process, and studies how ESG information flows are incorporated into and affect a dynamic portfolio with transaction costs. Two methods, called the ESG factor model and the ESG preference model, are considered to embed ESG information flows into a dynamic mean-variance model. The dynamic optimal portfolio can be expressed as a traditional optimal portfolio without ESG information and a dynamic ESG preference portfolio, and the impact of ESG information on optimal trading is explicitly analyzed. The rich numerical results show that ESG information can improve the out-of-sample performance, and ESG preference portfolio has the best out-of-sample performance including the net returns, Sharpe ratio and cumulative return of portfolios, and contribute to reducing risk and transaction costs. Our dynamic trading strategy provides valuable insights for sustainable investment both in theory and practice.
