Against the backdrop of systemic financial risk prevention and the pursuit of a virtuous cycle in the real economy, whether Local Government Financing Vehicles (LGFVs) shareholding alleviates maturity mismatch of corporate investment and financing activities is a question of critical importance, not only for the development of individual firms but also for high-quality macroeconomic growth. Using a sample of A-share listed firms in China’s Shanghai and Shenzhen stock exchanges from 2009 to 2021, this paper theoretically analyzes and empirically tests the impact of LGFVs shareholding on corporate maturity mismatch. The empirical results indicate that LGFVs shareholding can significantly alleviate corporate maturity mismatch and the finding is still robust across a series of empirical checks. Mechanism analyses show that LGFVs shareholding improves firms’ long-term financing capacity through a resource provision channel and restrains overinvestment through a governance optimization channel, thereby collectively mitigating corporate maturity mismatch. Further analysis indicates that the mitigating effect of LGFVs shareholding is more pronounced in firms with concentrated LGFVs shareholding, firms controlled by non-state-owned capital and firms under higher economic policy uncertainty. Our findings provide valuable theoretical insights for policy design aimed at optimizing corporate financial behavior and curbing corporate financial risks.

A central premise of mandatory disclosure regulation is that greater transparency reduces information asymmetry and lowers borrowing costs. We challenge this premise by examining industry-level operational disclosure - a regulatory form that reveals horizontally comparable information across peer firms rather than refining individual firm fundamentals. Exploiting the staggered introduction of mandatory industry-specific disclosure guidelines by Chinese stock exchanges between 2013 and 2019, we find that enhanced industry disclosure significantly widens bond credit spreads by approximately 54 basis points - the opposite of what standard disclosure theory predicts. This counterintuitive effect is more pronounced in non-homogeneous industries, among smaller firms, and for bonds restricted to institutional investors. Mechanism tests confirm two opposing channels: disclosure reduces information asymmetry while simultaneously intensifying product market competition by exposing strategically sensitive operational metrics. Our evidence challenges the one-size-fits-all approach to disclosure regulation and highlights that the competitive implications of disclosed information - not merely its quantity - shape credit risk pricing.

This study aims to elucidate the behaviors of the Shanghai and Shenzhen stock exchanges during extreme volatilities—China’s 2015 Stock Market Crash and the 2020 COVID-19 pandemic. Using topological data analysis (TDA), the study identiffes early warning signals within the Shanghai–Hong Kong (SHHK) and Shenzhen–Hong Kong Stock (SZHK) -Stock Connect markets. This timeliness ensures proactive market stabilization and portfolio adjust-ments. The results also reveal that the interconnected market signals are more stable, supporting multidimensional crisis detection and offering valu-able tools for policymakers and investors to effectively mitigate ffnancial risks.

We examine the impact of firm-investor communication on ESG issues through investor interactive platforms in Chinese stock exchanges from 2010 to 2022. Our regression analysis finds that increased ESG-based questions from investors and firms’ responses lead to increased stock liquidity, suggesting that investor-firm dialogues beyond financial aspects to include ESG-related themes contribute to greater information transparency. We posit that investors use such communication as a “voice” strategy, advocating firms for enhanced ESG disclosures and performance. This strategy yields a two-fold benefit: it aligns with investors’ ESG objectives and, alternatively, facilitates their exit through improved stock liquidity. Our robustness tests suggest a probable causal relationship between investor engagement on ESG issues and stock liquidity. Moreover, we find that a positive tone in ESG-based communications strengthens this relationship, prompting managers to enhance ESG disclosure transparency in response to investor pressure.

This study investigates the impact of investor attention on stock market reactions to ChatGPT using dialogues on the Chinese interactive investor platforms (IIPs). We measure investor attention by the number of investors’ questions toward ChatGPT on the IIPs and categorize the firms’ answers as Investing, Speculative, and Absent. The research reveals positive and statistically significant market reactions surrounding the initial questions that occur before firm responses. Positive abnormal returns are also observed around the initial answer dates, with Investing firms evoking the highest market response, followed by Speculative firms, and Absent firms exhibiting the lowest reactions. Furthermore, positive market reactions persist even as firms modify their ChatGPT involvement statements or face stock exchanges inquiries, suggesting that the stock price upswing may primarily be fueled by ChatGPT-related mania. Our findings imply the potential of ChatGPT fervor: collusion caused by investor attention to ChatGPT and firm’s responses catering to investors.

Purpose – The aim of this paper is to examine the effect of information disclosure by unlisted bond issuers on the stock price informativeness of listed firms in the same industry. Design/methodology/approach – This paper takes advantage of information disclosure during the bond issuance and examines the spillover effect of unlisted bond issuers’ information disclosure on listed firms in the stock market. The sample is composed of A-share firms listed on the Shanghai and Shenzhen stock exchanges from 2007 to 2018. All the data are obtained from the China Stock Market and Accounting Research and WIND databases. The impact of bond market information disclosure on price informativeness of listed firms in the same industry is identified through multivariate regression analyses. Findings – Empirical results show that price informativeness of listed firms has a significantly positive association with the information disclosure of same-industry unlisted bond issuers. Further analyses show that the above finding is more significant when information disclosure of bond issuers is a more important channel for acquiring industry information (i.e. when industry is more concentrated, when economic uncertainty is high, and when industry information is less transparent) and understanding the industry competitive landscape (i.e. when bond issuers are relatively large, when bond issuers and listed firms have more direct product competition, when bond issuance firms are large-scale state-owned business groups), and when there are more cross-market information intermediaries (i.e. more cross-market institutional investors and more sellside analysts).This paperindicates that information disclosure of bond issuers has a positive spillover effect on the stock market. Originality/value – The novelty of the research is that the authors examine industry information spillover from unlisted firms to listed firms leveraging on unlisted firms’ information disclosure in bond markets.

This study examines the impact of Shenzhen Stock Exchange’s (SZSE) information disclosure ratings on investment efficiency in China. Based on a sample of Chinese A-share listed companies on the SZSE from 2001 to 2018, we discover that superior information disclosure ratings improve investment efficiency after controlling for various firm- and industry-level variables. Our findings remain valid after various robustness tests and using instrumental variables to address the endogeneity problem. Specifically, we find that improving information disclosure ratings help firms attract more investor attention, which leads to higher investment efficiency. In addition, this information disclosure effect is more pronounced for underinvestment firms and firms on the main board than for smaller firms on SEM (small- and medium-sized enterprise) and GEM (growth enterprise market) boards. Our evidence supports the idea that regulatory activities for information disclosure ratings of companies listed on China’s stock exchanges improve investment efficiency.

We examine an important yet understudied form of reputational sanction in China, namely public criticisms imposed on culpable firms by the Chinese stock exchanges from 2013 to 2018. We find significantly negative cumulative abnormal returns around the announcement date, and they were affected by several factors, including financing propensity, governance mechanism, and equity nature. However, the market reaction is significantly negative only for firms relying on external financing and non-state enterprises, and importantly, becomes insignificant in cases where the firm had self-exposed misconduct before the official announcement of public criticism. Further, we examine other effects of public criticism, finding that public criticism does not improve firms’ long-term values, nor produce strong deterrence to change their behaviour. Overall, the evidence of the effects of public criticism on culpable firms is mixed, suggesting that reputational sanction is a weak, if not ineffective, instrument of market regulation in China.

We document that firms' strategic reactions could hamper the effectiveness of RegTech. Our paper focuses on one RegTech innovation in China—online platforms launched by stock exchanges for investors to communicate with listed companies. We find that firms provide a number of no-answer replies—answers without clear, specific, or useful information—to investors' questions. Consistent with strategic information hoarding, no-answers are shown to be associated with subsequent unfavorable news. Moreover, firms with higher no-answer rates tend to have lower price efficiency, higher return volatility, and higher stock price crash risk. The evidence suggests regulators' objective of enhancing investor protection is not fully fulfilled.

Using a sample of 1250 companies listed in Shanghai or Shenzhen Stock exchanges for the time period from 1999 to 2010, we find that for firms with a higher level of uncertainty, the benefits of the connections and advice provided by directors outweigh the costs of the impairment in decision making related to having a large board size. In particular, the positive incremental effect of board size on Q, for firms with a higher proportion of State shares, suggests that connections provided by directors is crucial for firms to get access to greater resources and it is even more important to Stateowned than to Non-State-owned firms during the economic reform in China. Our results indicate that that both agency theory and resource dependence theory play an important role on board efficient research.
