Using Chinese A-share listed firms from 2007 to 2024, this study examines whether supply chain shareholding (SCS) affects stock price synchronicity. We find that SCS significantly reduces stock price synchronicity. This finding remains robust to a series of robustness and endogeneity tests. Mechanism tests provide evidence consistent with information asymmetry and agency costs as two channels linking SCS to lower stock price synchronicity. Heterogeneity analyses show that the effect is more pronounced among firms with low supply chain concentration and those operating in unfavorable business environments. Overall, these findings identify SCS as a relationship-based governance arrangement that improves capital market information efficiency, particularly where relational governance and informal institutional substitution are more valuable.

This paper examines how potential disruptions from generative artificial intelligence (AI) to firms' core businesses affect their cross-industry acquisition decisions. Using data on Chinese A-share listed firms, we employ a large language model to assess the potential positive and negative effects of generative AI on core businesses and construct a measure of net AI risk exposure. We measure cross-industry M&A using the semantic distance between acquirers' and targets' business descriptions. A difference-in-differences analysis exploiting the commercial diffusion of generative AI shows that more exposed firms acquire more distant targets, with an effect equivalent to 8.2% of the sample mean and robust to alternative specifications. The effect is stronger among firms with narrower innovation boundaries and more concentrated business portfolios, consistent with innovation capability reconfiguration and strategic risk diversification. It is also stronger among firms with smaller market shares, in more competitive industries, and in more marketized regions. Further analyses show that high-exposure firms acquire targets with higher AI patent shares and receive more favorable announcement-day market reactions to distant acquisitions. Our findings suggest that potential AI-related disruptions shape acquisition target selection and firms' business boundaries.

Mergers and acquisitions (M&A) are widely regarded as a critical instrument for industrial consolidation and capacity rationalization. Utilizing a dataset of China’s major national and regional steel enterprises from 1998 to 2013, this study empirically evaluates the efficacy of M&A in resolving over1capacity. We document a striking heterogeneity in outcomes: while M&A generally alleviates overcapacity, this effect is exclusively driven by inter-provincial transactions; intra-provincial mergers show no significant impact. Mechanism analysis reveals that inter-provincial M&A facilitates the transfer of control rights, effectively insulating firms from local government intervention. In contrast, intra-provincial mergers are undermined by local intervention through mechanisms of "internal control" and "external defense." Furthermore, despite the reduction in capacity, we find that inter-provincial mergers suffer from incomplete post-merger integration. There is a persistent lack of governance coordination, and no convergence in capacity management performance is observed between the merging entities over time. These findings offer critical policy implications for mitigating local protectionism and enhancing integration efficiency to resolve industrial overcapacity.

This paper explores the impact of the Integrated Government Service Platform (IGSP) reform, a large-scale digital regulatory initiative in China, on firms’ investment efficiency. Using a firm-level panel dataset of Chinese listed firms, we find that the IGSP reform significantly enhances firms’ investment efficiency. Mechanism analyses indicate that the IGSP enhances firms’ investment efficiency by improving governance service quality and convergence of governance services across cities within a province, thereby reducing economic policy uncertainty and reinforcing market expectations. The heterogeneity analyses reveal that the effect is more pronounced for firms without political connections, those operating in high business volatility and high-tech industries, and regions with stronger informal institutions. Finally, the IGSP encourages firms to expand their investment activities to other cities within the same province. This finding is fully consistent with the underlying mechanisms identified in this study. Our findings provide novel evidence on the economic consequences of digital regulatory integration and offer policy implications for advancing service-oriented and efficiency-driven governance in developing economies.

This paper studies the role of the soft budget constraint in shaping firm dynamics and long-run economic growth. We develop a Schumpeterian model with two sectors: consumption and investment, and two types of firms: state-owned enterprises (SOEs) and privately owned enterprises (POEs). Within this framework, multi-product firms require fixed inputs of investment goods to operate — a resource that is also crucial for firm expansion, and the soft budget constraint allows subsidized firms to continue operating on loss-making product lines. This distortion raises the price of investment goods, suppresses firm dynamics, and dampens aggregate growth. To quantify the mechanism, the model is calibrated using Chinese firm-level data. Our quantitative exercise shows that eliminating the SOE soft budget constraint friction reduces the price of investment goods by 9.82 percent, increases the overall TFP growth rate by 0.12 percentage points, and generates a welfare gain of 4.94 percent.

We study machine-learning forecasts and portfolio allocation for Chinese government bonds. Penalised linear regressions and gradient-boosted trees predict next-month total returns for eight maturity buckets. Their forecasts feed mean–variance, Black–Litterman, and risk-budgeting implementations with weight, duration, and trading-cost controls; convexity, tail-risk, and attribution constraints are analysed separately as theoretical extensions. From January 2019 through December 2025, the three optimised cash portfolios earn net excess-return Sharpe ratios of 1.94–2.26 and maximum drawdowns of 0.18–0.25%. Three long-only bond-selection variants attain Sharpe ratios of 1.39–1.70. A futures-hedged arbitrage variant attains 1.08 under an 80% hedge-P&L scaling and basis-cost assumption. A stylised 10-year futures overlay reduces rather than improves cash-portfolio Sharpe ratios.

Our study examines dynamic innovation through the U.S.-Sino industrial-chain networks and its asset-pricing and financial-fundamental implications amid U.S.-China network disruptions. Innovation synergy captures similarity between firms’ learned innovation processes, in which firm characteristics and network information are used to predict patent output. Using an annually reconstructed joint network of Chinese and U.S. firms, we form peer-return, peer-R&D, and peer-patent measures and estimate their associations separately in the two markets. The annual R&D- and patent-based measures are positively associated with firms' own R&D intensity in both markets, their gross-profitability associations are stronger for large firms, and tangible-asset associations become more positive after 2017. The R&D- and patent-based long–short portfolios have positive Fama–French three-factor alphas in both markets, while the return-based signal is stronger in China than in the United States.

This study investigates how institutional resilience facilitates successful intergenerational succession in Chinese family firms. Drawing on institutional resilience theory and socioemotional wealth (SEW) theory, we employ fuzzy-set qualitative comparative analysis (fsQCA) to explore configurational causal pathways. Based on a sample of 20 Chinese family firms, we identify four core conditions (pre-succession planning, multi-dimensional governance structure, professional tool empowerment, cultural spirit inheritance) and one contextual condition (institutional environment adaptability). Results show that cultural spirit inheritance is the only necessary condition for successful succession, while five equifinal configurations of institutional resilience are sufficient to achieve effective succession. By contrast, weakness in any two core institutional resilience dimensions significantly increases the likelihood of succession failure. This study advances contextualized family business research by unpacking the combinatorial mechanisms of institutional resilience in an emerging market context and provides actionable implications for family firms and policymakers.

We examine whether campaign-based anti-corruption approaches effectively curb corruption in the long term. Our empirical setting exploits a unique anti-corruption campaign in the Chinese football community from 2009 to 2012. With match-fixing measured as abnormal points won in key matches, we find that although an anti-corruption campaign reduces match-fixing during its active phase, its long-term effect fades quickly, and the level of match-fixing significantly rebounds after the campaign ends. Our results indicate that without any institutional changes, combating corruption by launching intermittent campaigns has limited long-term effects.

Enhancing the performance of corporate green supply chain management (GSCM) represents a critical enabler for delivering on the central imperatives of the global low-carbon transition. Using panel data of Chinese listed companies from 2003 to 2022, this study employs a staggered difference-in-differences (DID) approach to examine the impact of the Low-Carbon City Pilot (LCCP) policy on firms' GSCM performance. The results show that the LCCP policy significantly improves firms' GSCM performance, and this effect remains robust across a range of sensitivity tests. Mechanism analyses reveal that the policy operates primarily by stimulating green innovation and increasing investment in environmental protection equipment. Furthermore, financial constraints play a significant moderating role: the positive effect of the policy on GSCM performance is stronger when firms face fewer financing constraints. Heterogeneity analysis indicates that the policy effects are more pronounced among non-heavy-polluting enterprises, those located in resource-dependent cities, and ISO 14001-certified enterprises. This study provides novel micro-level evidence on the environmental governance effects of place-based climate policies, and offers key policy implications for scaling up low-carbon city pilots and promoting corporate supply chain decarbonization.
