We examine the differential impacts of deep-level and surface-level board diversity on bank risk. Using data from Chinese listed banks between 2008 and 2023, we develop a research framework to empirically analyze these relationships. Results demonstrate that deep-level diversity significantly reduces bank risk, whereas surface-level diversity increases it. Mechanism analyses reveal that decision-making prudence, risk management capability, and managerial agency behavior mediate these relationships. Furthermore, moderation analyses indicate that meeting frequency strengthens the negative relationship between deep-level board diversity and bank risk and weakens the positive relationship between surface-level board diversity and bank risk. Conversely, remote board meetings weaken the ability of deep-level board diversity to reduce bank risk and strengthen the ability of surface-level board diversity to increase bank risk.
我们研究了深层和表层董事会多样性对银行风险的不同影响。利用2008年至2023年中国上市银行的数据,我们构建了一个研究框架来实证分析这些关系。结果表明,深层多样性显著降低银行风险,而表层多样性显著增加银行风险。机制分析表明,决策审慎性、风险管理能力和管理代理行为在这些关系中起中介作用。此外,适度性分析表明,会议频率强化了深层董事会多样性与银行风险之间的负向关系,削弱了表层董事会多样性与银行风险之间的正向关系。相反,远程董事会会议削弱了深层董事会多样性降低银行风险的能力,增强了表层董事会多样性增加银行风险的能力。

As artificial intelligence drives the technological revolution, understanding its impact on corporate non-financial governance is essential. Using unbalanced panel data of China’s A-share listed firms, in this study, we employ a multi-period difference-in-differences (DID) model to examine the impact of the Artificial Intelligence Innovation and Development Pilot Zones (AIIDPZ) on corporate environmental disclosure quality, treating the policy rollout as a quasi-natural experiment. We find that the establishment of AIIDPZ significantly elevates the quality of environmental information disclosure. This finding remains robust after a series of tests, including propensity score matching-DID, placebo tests, and corrections for potential biases in two-way fixed effects models. Moreover, AIIDPZ enhances environmental information disclosure quality by improving green total factor productivity and reducing R&D costs. Heterogeneity analysis indicates that larger firms, newer firms, highly competitive industries, and firms facing higher financing constraints benefit most from the establishment of AIIDPZ. Government subsidies and organizational inertia further amplify the impact of AIIDPZ on corporate environmental information disclosure. This study contributes empirical evidence on the micro-level environmental consequences of AI industrial policies and offers policy implications for promoting green development through digital intelligence.
随着人工智能推动技术革命,了解其对公司非财务治理的影响至关重要。本研究利用中国a股上市公司的非平衡面板数据,采用多期差分法(DID)模型,将人工智能创新发展试验区(AIIDPZ)政策的推出视为准自然实验,考察其对企业环境信息披露质量的影响。我们发现,AIIDPZ的建立显著提升了环境信息披露的质量。经过一系列的测试,包括倾向得分匹配did、安慰剂测试和对双向固定效应模型中潜在偏差的修正,这一发现仍然是强有力的。通过提高绿色全要素生产率和降低研发成本,提高环境信息披露质量。异质性分析表明,大企业、新企业、高竞争行业和融资约束程度较高的企业受益最大。政府补贴和组织惯性进一步放大了AIIDPZ对企业环境信息披露的影响。本研究为人工智能产业政策的微观环境后果提供了实证证据,并为通过数字智能促进绿色发展提供了政策启示。

Bridging behavioral insights and quantitative finance: AI-powered Black–Litterman framework with technical and sentiment signals 连接行为洞察和定量金融:人工智能驱动的Black-Litterman框架与技术和情绪信号
IF 6.9 2区 经济学 Q1 BUSINESS, FINANCE Pub Date : 2026-04-01 Epub Date: 2026-01-27 DOI: 10.1016/j.ribaf.2026.103329

Aiming to bridge quantitative finance with behavioral economics, this study harnesses artificial intelligence (AI) to integrate high-quality market sentiment into portfolio optimization. It evaluates the performance of the Black–Litterman (BL) asset allocation model, incorporating investor views generated from state-of-the-art deep learning (DL) models. These models are trained on three distinct datasets—technical (TD) derived from historical US sectoral ETF prices, sentiment (SD) obtained from Refinitiv’s MarketPsych Analytics (LSEG), and their combination (TSD). The proposed framework replaces subjective expert views with data-driven forecasts to enhance accessibility for retail investors. Portfolios are constructed with daily rebalancing based on DL-forecasted prices and account for transaction costs under different market regimes and risk aversion rates. The findings reveal that BL models incorporating the integrated TSD with lower risk aversion (λ=1) significantly outperform those based on TD, SD, or traditional benchmarks, underscoring the robustness of combining technical and sentiment signals for view generation and highlighting its effectiveness for growth-oriented strategies. Under normal market conditions, TD and SD-based portfolios exhibit comparable average performance on risk-adjusted evaluation metrics; however, in high-volatility regimes, TD-based portfolios consistently outperform their SD counterparts on average. This study advocates for TSD-based, DL-enhanced BL models with lower risk aversion as a robust strategy in dynamic market environments, offering practical guidance for retail investors and insights for policymakers on harnessing AI to strengthen financial decision-making.
本研究旨在架起定量金融与行为经济学的桥梁,利用人工智能(AI)将高质量的市场情绪整合到投资组合优化中。它评估了Black-Litterman (BL)资产配置模型的表现,并结合了最先进的深度学习(DL)模型产生的投资者观点。这些模型是在三个不同的数据集上进行训练的:技术数据集(TD)来自美国行业ETF的历史价格,情绪数据集(SD)来自Refinitiv的市场心理分析(LSEG),以及它们的组合(TSD)。拟议的框架用数据驱动的预测取代了主观的专家观点,以提高散户投资者的可及性。投资组合的构建是基于dl预测价格的每日再平衡,并考虑不同市场制度和风险规避率下的交易成本。研究结果表明,将整合的TSD与较低的风险厌恶(λ=1)相结合的BL模型显著优于基于TD、SD或传统基准的模型,强调了将技术和情绪信号结合起来进行视图生成的鲁棒性,并强调了其对增长导向策略的有效性。在正常的市场条件下,基于TD和sd的投资组合在风险调整后的评估指标上表现出相当的平均表现;然而,在高波动性的情况下,基于td的投资组合的平均表现始终优于SD。本研究提倡将基于tsd的、具有较低风险厌恶度的dl增强BL模型作为动态市场环境中的稳健策略,为散户投资者提供实用指导,并为政策制定者提供利用人工智能加强金融决策的见解。

Do climate risk and ESG sentiment predict clean energy performance? Evidence from quantile-on-quantile analysis 气候风险和ESG情绪能否预测清洁能源绩效?来自分位数对分位数分析的证据
IF 6.9 2区 经济学 Q1 BUSINESS, FINANCE Pub Date : 2026-04-01 Epub Date: 2026-01-22 DOI: 10.1016/j.ribaf.2026.103327

This study examines the predictive power of climate risk and ESG sentiment on the performance of clean energy markets using novel non-parametric econometric techniques. To capture the dependence structures and asymmetries across the conditional distribution of returns, we employ univariate quantile-on-quantile regression (QQR), multivariate quantile-on-quantile regression (MQQR), quantile-on-quantile Granger causality (QQGC), and quantile-on-quantile connectedness (QQC) approaches using data from May 2015 to March 2025. Our findings indicate that ESG momentum is a significant and state-contingent predictor of clean energy returns, with its influence most substantial under bullish market regimes or during recovery phases following downturns. Climate policy uncertainty (CPU) exhibits a nonlinear and asymmetric impact, exerting the most significant predictive power and connectedness during both pessimistic and euphoric states. Investor attention (ATT), while more erratic, plays an amplification role under extreme sentiment conditions. The MQQR model reveals that the effects of ESG, CPU, and ATT are not isolated but interactively reinforce or offset each other, depending on the prevailing market state. The QQGC and QQC results validate the robustness of these interdependencies, confirming that dynamic, joint effects of sentiment and policy signals shape the sensitivity of clean energy markets.
本研究使用新颖的非参数计量经济学技术,检验了气候风险和ESG情绪对清洁能源市场表现的预测能力。为了捕捉收益条件分布的依赖结构和不对称性,我们使用了单变量分位数对分位数回归(QQR)、多变量分位数对分位数回归(MQQR)、分位数对分位数格兰杰因果关系(QQGC)和分位数对分位数连通性(QQC)方法,使用了2015年5月至2025年3月的数据。我们的研究结果表明,ESG势头是清洁能源回报的重要预测指标,其影响在看涨市场制度或经济衰退后的复苏阶段最为显著。气候政策不确定性(CPU)表现出非线性和不对称的影响,在悲观和乐观状态下都发挥了最显著的预测能力和连通性。投资者关注(ATT)虽然更加不稳定,但在极端情绪条件下发挥放大作用。MQQR模型表明,ESG、CPU和ATT的影响不是孤立的,而是相互增强或相互抵消的,这取决于当前的市场状态。QQGC和QQC结果验证了这些相互依赖性的稳健性,证实了情绪和政策信号的动态联合效应塑造了清洁能源市场的敏感性。

Local optimistic expectations and corporate capital structure decisions 地方乐观预期与企业资本结构决策
IF 6.9 2区 经济学 Q1 BUSINESS, FINANCE Pub Date : 2026-04-01 Epub Date: 2026-01-13 DOI: 10.1016/j.ribaf.2026.103299

This study investigates the influence of local optimistic expectations on corporate capital structure decisions. Leveraging a sample of Chinese A-share listed firms from 2010 to 2022, we document a robust positive association between regional optimism and corporate leverage ratios. This effect is particularly salient among firms that rely on short-term debt and operate in financially constrained regions. Instrumental variable regressions substantiate a causal interpretation of these findings. The results remain robust across a battery of sensitivity tests, including alternative variable definitions and sample restrictions. Mechanism analysis indicates that optimism shapes capital structure by driving investment expansion and amplifying the transmission of market sentiment. Collectively, our findings underscore the pivotal role of collective sentiment in shaping micro-level financial policies.
本研究探讨了地方乐观预期对公司资本结构决策的影响。利用2010年至2022年中国a股上市公司的样本,我们证明了区域乐观情绪与企业杠杆率之间存在显著的正相关关系。这种影响在依赖短期债务和在财政紧张地区经营的公司中尤为突出。工具变量回归证实了这些发现的因果解释。在一系列敏感性测试中,包括替代变量定义和样本限制,结果仍然是可靠的。机制分析表明,乐观情绪通过驱动投资扩张和放大市场情绪传导来塑造资本结构。总的来说,我们的研究结果强调了集体情绪在制定微观金融政策方面的关键作用。

Connectedness and risk transmission across artificial intelligence industries 人工智能行业之间的连通性和风险传递
IF 6.9 2区 经济学 Q1 BUSINESS, FINANCE Pub Date : 2026-04-01 Epub Date: 2026-02-05 DOI: 10.1016/j.ribaf.2026.103335

Artificial Intelligence (AI) has emerged as a key innovation in the global economy, with AI-related equities becoming major drivers of the recent stock market upswing. Yet, the internal dynamics and heterogeneity within the AI sector remain largely unexplored. We address this gap by analyzing the connectedness and risk transmission among four AI industries: hardware manufacturers, cloud providers, application developers, and AI-intensive BigTech firms, using self-constructed stock market indices for 2023–2025. Adopting an industry-level perspective, we explicitly account for the heterogeneous structure of the AI sector. By capturing both static dependence and dynamic patterns, we assess how intrasectoral relationships evolve over time and under varying market conditions. Results indicate strong positive relationships among the four AI industries, which intensify during periods of market stress. Cross-industry spillovers account for more than half of return variation in the AI sector, though they remain modest under normal conditions. During sharp market swings, particularly downturns, shocks propagate widely across all industries. While AI hardware manufacturers and AI BigTech typically act as net shock transmitters and AI application developers and cloud providers as net receivers, their roles shift over time. Our results emphasize the need for dynamic hedging, as static diversification offers limited protection in stressed markets, and closer monitoring of cross-industry exposures. Given the growing dependence of many sectors on AI infrastructure, disruptions in key AI segments may have wider systemic effects and should be incorporated into macroprudential oversight.
人工智能(AI)已成为全球经济中的一项关键创新,与AI相关的股票成为近期股市上涨的主要推动力。然而,人工智能领域的内部动态和异质性在很大程度上仍未得到探索。我们通过分析四个人工智能行业之间的连通性和风险传递来解决这一差距:硬件制造商、云提供商、应用程序开发商和人工智能密集型大技术公司,使用自建的2023-2025年股票市场指数。采用行业层面的观点,我们明确说明了人工智能部门的异质结构。通过捕获静态依赖和动态模式,我们评估了部门内关系如何随着时间和不同的市场条件而演变。结果表明,四个人工智能行业之间存在很强的正相关关系,这种关系在市场压力期间会加剧。跨行业溢出效应占人工智能行业回报变化的一半以上,尽管在正常情况下仍然不大。在市场剧烈波动期间,尤其是在经济低迷时期,冲击会在所有行业广泛传播。虽然人工智能硬件制造商和人工智能大技术通常是净冲击发射器,人工智能应用程序开发商和云提供商是净接受者,但他们的角色随着时间的推移而变化。我们的研究结果强调了动态对冲的必要性,因为静态多样化在压力市场中提供了有限的保护,并且更密切地监测跨行业风险敞口。鉴于许多行业越来越依赖人工智能基础设施,关键人工智能领域的中断可能会产生更广泛的系统性影响,应将其纳入宏观审慎监管。

Carbon emissions and discontinued operations 碳排放和已停产业务

The Porter Hypothesis argues that pollution is often a sign of resource misallocation and operational inefficiency, and that environmental challenges, rather than acting purely as a cost, can drive firms to improve efficiency, innovate, and restructure. Building on this theoretical framework, we examine whether carbon emissions, as a proxy for environmental inefficiency, are associated with firms’ decisions to discontinue business operations. Using a sample of 33,323 U.S. firm-year observations from 2002 to 2023 and carbon emissions data from Trucost, we find a significant positive relation between emissions and the likelihood of discontinued operations, suggesting that firms with more emissions are more likely to discontinue business operations.
波特假说认为,污染往往是资源配置不当和运营效率低下的标志,环境挑战,而不是纯粹的成本,可以推动企业提高效率,创新和重组。在这一理论框架的基础上,我们考察了碳排放作为环境效率低下的代表,是否与企业停止经营的决定有关。使用33,323个样本 美国从2002年到2023年的企业年度观察和Trucost的碳排放数据来看,我们发现碳排放与停止经营的可能性之间存在显著的正相关关系,这表明碳排放越多的企业越有可能停止经营。

Liquidity creation in dual banking systems: Do insolvency reforms matter? 双重银行体系下的流动性创造:破产改革重要吗?
IF 6.9 2区 经济学 Q1 BUSINESS, FINANCE Pub Date : 2026-04-01 Epub Date: 2026-01-17 DOI: 10.1016/j.ribaf.2026.103312

Although several aspects of liquidity creation have been addressed in the literature, one area that appears to have been largely bypassed is the impact of insolvency reforms. To address this issue, we utilise bank-level data for countries with dual banking systems from 2010 to 2020 and assess its impact. In this regard, we exploit the staggered nature of insolvency reforms across countries and use a difference-in-differences specification to assess their impact. The findings reveal that insolvency reforms reduce banks' liquidity creation by an average of 2.8 per cent, primarily on the asset side.

尽管流动性创造的几个方面已经在文献中得到了解决,但有一个领域似乎在很大程度上被忽略了,那就是破产改革的影响。为了解决这一问题,我们利用2010年至2020年实行双重银行制度的国家的银行层面数据,并评估其影响。在这方面,我们利用各国破产改革的交错性质,并使用差异中之差规范来评估其影响。研究结果显示,破产改革使银行的流动性创造平均减少2.8%,主要是在资产方面。这种影响在传统银行和伊斯兰银行之间是不同的,在资产和负债方面也是不同的。我们认为,这是实行双重银行制度的国家评估破产改革与创造流动性之间关系的一项早期工作。

How Environment, Society and Governance (ESG) affect economic welfare has been widely studied, however, how each pillar influences each other is under-explored. In this study, from a cross-country perspective, we explore how environmental policy influences the country-level social-pillar performance by focusing on the labor employment in the Association of Southeast Asian Nations (ASEAN). Based on multinational data of the ASEAN countries from 2000 to 2021, we find that the implementation of feed-in tariffs (FIT) policy, a key renewable energy promotion policy, significantly reduce unemployment rate in the ASEAN region. The two primary channels include that the renewable energy policy promotes industrial expansion and lowers the energy price. Further, we find that the FIT policy help decrease unemployment rate in countries with better fundamental infrastructure, stable political environment, lower reliance on traditional energy, and more foreign inflows. Moreover, we find that the economic linkages with China amplify the policy effect. This study shows that the environmental policy can help improve social condition in developing countries, and these countries need to upgrade domestic infrastructure and use foreign support to promote the positive effect.
环境、社会和治理(ESG)如何影响经济福利已被广泛研究,然而,各支柱如何相互影响尚未得到充分探讨。本研究以东南亚国家联盟(ASEAN)劳工就业为研究对象,从跨国视角探讨环境政策对国家层面社会支柱绩效的影响。基于2000年至2021年东盟国家的跨国数据,我们发现,可再生能源推广的关键政策——上网电价政策的实施显著降低了东盟地区的失业率。可再生能源政策促进产业扩张和降低能源价格是两个主要渠道。此外,我们发现,在基础设施较好、政治环境稳定、对传统能源依赖程度较低、外资流入较多的国家,上网电价补贴政策有助于降低失业率。此外,我们发现与中国的经济联系放大了政策效应。研究表明,环境政策有助于改善发展中国家的社会状况,这些国家需要升级国内基础设施并利用国外支持来促进其积极作用。

Short debt, long pain: How does accounting supervision amplify Chinese corporate maturity mismatch? 短债长痛:会计监管如何放大中国企业期限错配?
IF 6.9 2区 经济学 Q1 BUSINESS, FINANCE Pub Date : 2026-04-01 Epub Date: 2026-01-16 DOI: 10.1016/j.ribaf.2026.103311

Based on manually collected accounting supervision data from 2006 to 2021, this study examines the impact of the policy on short-term debt for long-term investment (SDLI). Results indicate that firms identified with accounting information quality issues experience an increase in SDLI. Mechanism analysis reveals that these firms face both reputational damage and constrained external financing. Furthermore, heterogeneity analyses indicate that the effect is more pronounced among firms in the growth stage, with less asset reversibility, and with higher risk-taking. The research enriches the literature on government regulation and SDLI, offering valuable insights for policymakers and corporate risk management.
基于2006年至2021年人工收集的会计监管数据,本研究考察了政策对长期投资短期债务(SDLI)的影响。结果表明,认同会计信息质量问题的公司在SDLI方面有所增加。机制分析表明,这些企业既面临声誉受损,又面临外部融资受限。此外,异质性分析表明,在资产可逆性较低、风险承担较高的成长期企业中,这种影响更为明显。该研究丰富了政府监管与SDLI的相关文献,为政策制定者和企业风险管理提供了有价值的见解。
