While recent evidence finds negative consequences of the public scrutiny following index inclusion, we investigate its potential benefits for corporate governance. Utilizing the cutoff rules between the CSI 300 and CSI 500 indices, this paper employs a Regression Discontinuity Design (RDD) to identify the causal effect of CSI 300 inclusion on Enterprise Risk Management (ERM) adoption. We find that CSI 300 inclusion significantly promotes ERM adoption, primarily through a “monitoring effect” manifested in increased analyst coverage, media attention, and investor attention. Furthermore, this effect is significantly stronger for firms that attract more stock forum discussions and had received regulatory penalties prior to their initial index inclusion. Our findings suggest that public scrutiny following CSI 300 inclusion can serve as an important catalyst for improving fundamental governance structures, thereby highlighting a significant but previously overlooked determinant of corporate risk governance.
虽然最近的证据发现纳入指数后公众监督的负面影响,但我们调查了其对公司治理的潜在好处。利用沪深300指数和沪深500指数之间的截止规则,本文采用回归不连续设计(RDD)来确定纳入沪深300指数对企业风险管理(ERM)采用的因果关系。我们发现,纳入沪深300显著促进了ERM的采用,主要是通过“监测效应”表现在分析师报道、媒体关注和投资者关注的增加。此外,对于吸引更多股票论坛讨论并在最初纳入指数之前受到监管处罚的公司,这种影响明显更强。我们的研究结果表明,在沪深300指数纳入后,公众监督可以作为改善基本治理结构的重要催化剂,从而突出了公司风险治理的一个重要但以前被忽视的决定因素。

This paper explores the relationship between digital trade (DT), financial accessibility, and cross-border capital flows based on data from China's A-share listed companies between 2010 and 2023. The conclusions of this paper are as follows: DT has a positive impact on cross-border capital flows; the positive influence of DT on cross-border capital flows exhibits heterogeneity across firms at different stages of their life cycle; and financial accessibility plays a mediating role between DT and cross-border capital flows. This study not only enriches the theoretical research on DT and cross-border capital flows but also provides useful references for relevant policy formulation and optimizing corporate operational strategies.
本文基于2010 - 2023年中国a股上市公司数据,探讨了数字贸易、金融可及性和跨境资本流动之间的关系。本文的结论是:DT对跨境资本流动具有正向影响;创新对跨境资本流动的正向影响在企业生命周期的不同阶段呈现异质性;金融可及性在DT与跨境资本流动之间起中介作用。本研究不仅丰富了DT与跨境资本流动的理论研究,也为相关政策的制定和企业运营策略的优化提供了有益的参考。

This study explores how ESG controversies affect to the cost of debt and equity. On a sample of 474 non-financial firms listed on the STOXX Europe 600 from 2016 to 2023, we show that ESG controversies significantly affect both categories of financing costs. The effects vary across ESG sub-pillars and are influenced by factors such as country-level regulatory quality, firm size, and default probability. Furthermore, based on Legitimacy Theory, we identify market uncertainty as a key transmission channel: ESG controversies raise questions about a firm’s legitimacy to operate, prompting stakeholder concerns about future conduct, regulatory fines, and profitability, ultimately worsening financing conditions.
本研究探讨了ESG争议对债务和股权成本的影响。我们以2016年至2023年在斯托克欧洲600指数上市的474家非金融公司为样本,发现ESG争议对两类融资成本都有显著影响。ESG各子支柱的影响各不相同,并受到国家层面监管质量、公司规模和违约概率等因素的影响。此外,基于合法性理论,我们认为市场不确定性是一个关键的传导渠道:ESG争议引发了对公司运营合法性的质疑,促使利益相关者对未来行为、监管罚款和盈利能力的担忧,最终导致融资条件恶化。

Cyber risk, 10-K report and audit fees 网络风险,10-K报告和审计费用
IF 6.9 2区 经济学 Q1 BUSINESS, FINANCE Pub Date : 2026-03-01 Epub Date: 2026-01-10 DOI: 10.1016/j.frl.2026.109496

Cybersecurity risk has become a material concern for firms, regulators, and auditors, yet credible ex-ante indicators of cyber vulnerability remain difficult to observe. This paper examines whether firms’ cybersecurity disclosures in 10-K filings convey forward-looking information about future cyber incidents and whether auditors incorporate such information into audit pricing and engagement decisions. Using a cosine-similarity measure that captures how closely a firm’s cybersecurity risk disclosures resemble those of firms that recently experienced cyber-attacks, we construct a disclosure-based proxy for ex-ante cyber risk. We find that a one-standard-deviation increase in this cosine index is associated with a 0.61-percentage-point increase in the probability of a subsequent cyber incident-approximately a 25% increase relative to the sample mean. We further show that higher disclosure-based cyber risk is associated with significantly higher audit fees (about 4.7%, or USD 130,000) and a greater likelihood of being audited by a Big Four firm. These findings suggest that auditors actively extract and price cyber-risk signals from narrative disclosures, rather than reacting only after cyber incidents occur. More broadly, our results highlight the growing role of mandatory risk disclosures as a forward-looking source of information about firms’ operational vulnerabilities.
网络安全风险已成为企业、监管机构和审计机构的重大担忧,但可信的事前网络脆弱性指标仍然难以观察到。本文考察了公司在10-K文件中的网络安全披露是否传达了有关未来网络事件的前瞻性信息,以及审计师是否将此类信息纳入审计定价和业务决策。使用余弦相似度度量来捕捉公司的网络安全风险披露与最近遭受网络攻击的公司的网络安全风险披露的接近程度,我们构建了一个基于披露的事前网络风险代理。我们发现,余弦指数每增加一个标准差,随后发生网络事件的概率就会增加0.61个百分点——相对于样本均值,大约增加25%。我们进一步表明,更高的基于披露的网络风险与更高的审计费用(约4.7%,或13万美元)和更大的被四大会计师事务所审计的可能性相关。这些发现表明,审计师积极地从叙述性披露中提取和定价网络风险信号,而不是在网络事件发生后才做出反应。更广泛地说,我们的研究结果强调了强制性风险披露作为企业运营脆弱性前瞻性信息来源的作用日益增强。

Does fiscal decentralization promote corporate green transition? 财政分权是否促进企业绿色转型?
IF 6.9 2区 经济学 Q1 BUSINESS, FINANCE Pub Date : 2026-03-01 Epub Date: 2025-12-24 DOI: 10.1016/j.frl.2025.109428

As sustainable development increasingly gains global attention, corporate green transformation has become a key pathway toward high-quality economic growth. This study examines whether and how local fiscal autonomy influences firms’ green transformation from an institutional perspective of fiscal decentralization (FD). Using panel data from Chinese prefecture-level cities and nonfinancial listed firms, we construct a text-based index to quantify green transformation and apply a two-way fixed effects model for empirical analysis. The results reveal that FD significantly promotes green transformation, and the findings remain robust following various validity tests. Mechanism analysis reveals that FD indirectly facilitates green transformation by strengthening local environmental regulation and increasing executives’ political connections. Quantile regression analysis indicates significant heterogeneity, with positive effects primarily concentrated among firms with stronger green foundations. This study extends the understanding of FD at the micro level and provides empirical support for better alignment between fiscal reform and sustainability policy.
随着可持续发展日益受到全球关注,企业绿色转型已成为实现经济高质量增长的重要途径。本研究从财政分权的制度视角考察了地方财政自治是否以及如何影响企业绿色转型。本文利用中国地级市和非金融上市公司的面板数据,构建了基于文本的绿色转型量化指标,并运用双向固定效应模型进行实证分析。结果表明,FD显著促进了绿色转型,并且经过各种效度检验,研究结果仍然稳健。机制分析表明,FD通过加强地方环境监管和增加高管的政治联系,间接促进了绿色转型。分位数回归分析显示异质性显著,积极效应主要集中在绿色基础较强的企业。本研究拓展了微观层面对财政赤字的理解,为财政改革与可持续性政策的更好衔接提供了实证支持。

This study explores the role of environmental, social, and governance (ESG) investment in mitigating fund risk and enhancing portfolio resilience, using Chinese mutual fund data from 2009 to 2022. We find that ESG investment in funds significantly decreases fund risk. The risk-reduction benefits are more pronounced for funds that are signatories to the Principles for Responsible Investment (PRI). Moreover, ESG-integrated funds exhibit lower risk and greater resilience during periods of adverse markets and heightened ESG-related attention. We further show that ESG investment is associated with lower tail risk, lower ambiguity, and higher net returns. These findings highlight the significance of ESG investing as a strategic tool for strengthening portfolio resilience and promoting financial stability.
本文利用2009年至2022年的中国共同基金数据,探讨了环境、社会和治理(ESG)投资在降低基金风险和增强投资组合弹性方面的作用。我们发现ESG对基金的投资显著降低了基金风险。对于签署了负责任投资原则(PRI)的基金来说,降低风险的好处更为明显。此外,整合esg的基金在市场不利时期表现出更低的风险和更大的弹性,并引起了与esg相关的高度关注。我们进一步表明,ESG投资与较低的尾部风险、较低的模糊性和较高的净回报相关。这些发现突出了ESG投资作为加强投资组合弹性和促进金融稳定的战略工具的重要性。

Climate policy uncertainty and green premium: Evidence from China 气候政策不确定性与绿色溢价:来自中国的证据
IF 6.9 2区 经济学 Q1 BUSINESS, FINANCE Pub Date : 2026-03-01 Epub Date: 2026-01-22 DOI: 10.1016/j.frl.2026.109563

We examine the pricing effect of climate policy uncertainty on green bonds in a transitional economy with rapidly developing green financing market. We find a significant relationship between green premium and climate policy uncertainty in China. When climate policy uncertainty is high, the yield difference between green bonds and their conventional “twin” bonds (green premium) increases, suggesting that investors in China demand higher compensation during these periods rather than perceiving green bonds as a valid hedge against policy uncertainty. This effect is more pronounced for green bonds issued in climate sensitive regions (northern regions), with higher green credibility (certified by third party), and higher exposure to climate policy (issued in large sizes), suggesting a weaker signaling of certification and high risk of green projects during periods with heightened climate policy uncertainty. Our results are robust across alternative model specifications, macroeconomic factors and various fixed effects. Two channels, financial market development and green commitment, are identified through which local conditions buffer the impact of CPU on green bond premium.
本文研究了在绿色融资市场快速发展的转型经济中,气候政策不确定性对绿色债券定价的影响。研究发现,绿色溢价与中国气候政策不确定性之间存在显著关系。当气候政策不确定性较高时,绿色债券与其传统的“孪生”债券(绿色溢价)之间的收益率差增大,这表明中国投资者在此期间要求更高的补偿,而不是将绿色债券视为对抗政策不确定性的有效对冲。这种影响对于在气候敏感地区(北方地区)发行的绿色债券更为明显,这些地区绿色信誉较高(经第三方认证),气候政策风险较高(大规模发行),这表明在气候政策不确定性加剧的时期,绿色项目的认证信号较弱,风险较高。我们的结果在不同的模型规格、宏观经济因素和各种固定效应中都是稳健的。通过金融市场发展和绿色承诺两个渠道,本地条件可以缓冲CPU对绿色债券溢价的影响。

Financial support for sustainability under environmental regulation: The role of patient capital 环境监管下对可持续发展的金融支持:耐心资本的作用
IF 6.9 2区 经济学 Q1 BUSINESS, FINANCE Pub Date : 2026-03-01 Epub Date: 2025-12-20 DOI: 10.1016/j.frl.2025.109414

Amid increasingly stringent environmental regulations, the influence of green finance on promoting corporate and regional sustainability has gained growing attention, yet its underlying mechanisms and effective boundaries are insufficiently explored. This study constructs an analytical framework linking green finance, patient capital, and sustainable development using Chinese listed-firm and provincial data from 2010 to 2022 to examine whether green finance enhances corporate sustainability and regional sustainable development, and mediating mechanism of patient capital. The empirical results reveal that green finance significantly strengthens firms’ sustainable development capacity and environmental, social, and governance performance, while also improving regional sustainability. Patient capital—measured using relational debt and long-horizon institutional ownership—is a crucial transmission channel. In addition, green finance exhibits an inverted U-shaped effect, with stronger impacts in regions with a lower sustainability baseline and diminishing marginal effects in more developed regions. The results reveal the internal financial–governance mechanism through which green finance operates under environmental regulation and provides empirical evidence for optimizing the scale of green finance and designing region-specific green policy tools. Our findings provide valuable insights for refining long-term green transition strategies.
在环境监管日益严格的背景下,绿色金融对促进企业和区域可持续发展的作用日益受到关注,但其潜在机制和有效边界却没有得到充分的探索。本文利用2010 - 2022年中国上市公司和省级数据,构建绿色金融、耐心资本与可持续发展的关联分析框架,考察绿色金融对企业可持续发展和区域可持续发展的促进作用,以及耐心资本的中介机制。实证结果表明,绿色金融显著增强了企业的可持续发展能力和环境、社会和治理绩效,同时也显著提高了区域可持续性。用关系债务和长期机构所有权衡量的耐心资本是关键的传导渠道。此外,绿色金融呈现倒u型效应,对可持续性基线水平越低的地区影响越强,对可持续性基线水平越高的地区边际效应越小。研究结果揭示了绿色金融在环境规制下运行的内部金融治理机制,为优化绿色金融规模和设计有区域特色的绿色政策工具提供了实证依据。我们的研究结果为完善长期绿色转型战略提供了有价值的见解。

This paper proposes a Generative Adversarial Network (GAN)–based framework for risk-neutral option pricing that learns the empirical distribution and temporal structure of log-return noise. By extracting and modeling stochastic noise from historical returns, the framework generates risk-neutral price paths for option valuation and delta prediction. We evaluate three state-of-the-art GAN architectures, including TimeGAN, QuantGAN, and SigCWGAN, against Monte Carlo simulation, the Black–Scholes–Merton, and Heston models across market regimes, maturities, moneyness levels, and option types. Empirical results show that QuantGAN and SigCWGAN accurately replicate key distributional and autocorrelation properties of return noise and consistently outperform benchmark models in option pricing, particularly in stable market environments and around at-the-money regions where pricing accuracy is most critical. Across a broad range of market conditions, these models deliver lower pricing errors and higher statistical confidence measures than traditional benchmarks. While pricing performance deteriorates during periods of abrupt volatility shifts, GAN-based models remain competitive overall. In contrast, improvements in delta prediction are limited, especially near mid-delta regions where payoff curvature is steepest. Overall, the findings demonstrate that learning stochastic noise offers an effective and flexible data-driven alternative for risk-neutral option pricing, while reliable sensitivity estimation requires models that jointly capture distributional features and local dynamic responses of the underlying asset.
本文提出了一种基于生成对抗网络(GAN)的风险中性期权定价框架,该框架学习了对数收益噪声的经验分布和时间结构。通过从历史收益中提取随机噪声并对其建模,该框架为期权估值和delta预测生成风险中性的价格路径。我们评估了三种最先进的GAN架构,包括TimeGAN、QuantGAN和SigCWGAN,对比蒙特卡罗模拟、Black-Scholes-Merton和Heston模型,涉及市场制度、期限、资金水平和期权类型。实证结果表明,QuantGAN和SigCWGAN准确地复制了收益噪声的关键分布和自相关特性,并在期权定价中始终优于基准模型,特别是在稳定的市场环境和围绕定价准确性最关键的货币区域。在广泛的市场条件下,这些模型比传统基准提供更低的定价误差和更高的统计置信度。虽然定价性能在突然波动期间会恶化,但基于gan的模型总体上仍具有竞争力。相比之下,delta预测的改进是有限的,特别是在收益曲率最陡峭的中delta区域附近。总体而言,研究结果表明,学习随机噪声为风险中性期权定价提供了一种有效和灵活的数据驱动替代方案,而可靠的灵敏度估计需要模型共同捕获标的资产的分布特征和局部动态响应。

Corporate corruption governance: the inhibitory effect of digital transformation on fintech 公司腐败治理:数字化转型对金融科技的抑制作用

Corporate corruption remains a significant challenge to governance and economic stability. This study investigates the efficacy of technological solutions by examining how financial regulatory technology (Fintech), within the broader context of corporate digital transformation, inhibits internal corruption. Using a panel dataset of Chinese publicly listed firms from 2013 to 2023, this study find robust evidence that the adoption of Fintech significantly curtails corruption. Crucially, this deterrent effect is amplified by the firm's digital transformation, indicating a powerful synergy between specific regulatory tools and systemic organizational change. The benefits, however, are not uniform. Heterogeneity analysis reveals that larger firms, with greater resources and more complex structures, derive more significant anti-corruption benefits from Fintech. Furthermore, the moderating effect of digital transformation is most pronounced in firms with high investment levels, which enables a more profound technological integration. These findings highlight that isolated technological solutions are insufficient; rather, a holistic digital strategy is key to enhancing corporate integrity.
企业腐败仍然是对治理和经济稳定的重大挑战。本研究通过考察金融监管技术(Fintech)如何在企业数字化转型的更广泛背景下抑制内部腐败,来调查技术解决方案的有效性。利用2013年至2023年中国上市公司的面板数据集,本研究发现了强有力的证据,表明金融科技的采用显著减少了腐败。至关重要的是,这种威慑效应被公司的数字化转型放大了,这表明特定监管工具和系统性组织变革之间存在强大的协同作用。然而,这些好处并不统一。异质性分析表明,拥有更多资源和更复杂结构的大公司从金融科技中获得的反腐败利益更显著。此外,数字化转型的调节效应在高投资水平的企业中最为明显,这使得技术整合更加深入。这些发现突出表明,孤立的技术解决方案是不够的;相反,全面的数字战略是提高企业诚信的关键。
