This study shows how price limit rules, intended to stabilize markets, inadvertently distort price dynamics by fostering strategic speculation. Through a dynamic rational expectations model, we demonstrate that price limits induce post limit-up price jumps by impeding full information incorporation, enabling speculators to artificially push prices to upper bounds and exploit uninformed traders. The model predicts two distinct patterns: (1) stocks closing at price limits exhibit positive overnight returns followed by long-term reversals, and (2) stocks retreating from upper bounds suffer sharp reversals with partial recovery. Empirical analysis confirms these predictions. A natural experiment from China’s 2020 GEM reform —- which widened the price limit -— further provides causal evidence that relaxed limits mitigate speculative distortions.

Exploiting a unique market-oriented media reform initiated in 1996 in China, we investigate the role of media environment in affecting firm behaviour. We find robust evidence that market-oriented media environment is conductive to firm innovation, with the reform promoting patent quantity and quality substantially. The effect is more pronounced for firms with higher information asymmetry. Matching firm data with 1.3 million news reports, we find the market-oriented media reform significantly improves the criticalness and unbiasedness of news coverage and shapes an innovation-friendly environment. Our findings highlight economic outcomes of relaxing media control and underline substantial gains from deepening the reform.

Under the guidance of the dual-carbon target, the development of the carbon financial system is of great significance to compensate for the gap between green and low-carbon investment. Considering the current state of the development of carbon financial system, China has initially formed a carbon financial system, including participants, carbon financial products and macro and micro operation structures, but the system is still in the initial development stage. Given the current restrictions on the development of carbon finance, it can be seen that there are still problems such as unreasonable economic structure, insufficient market construction, single product category, low utilization rate and urgent construction of relevant judicial guarantee system. Therefore, the system should be improved at the economic level and the legal level. The economic level includes adjusting the layout of economic development structure, strengthening the construction of market infrastructure, encouraging the diversification of carbon financial products and strengthening publicity and education promotion strategies. The legal level includes improving the top-level design, formulating judicial interpretation to promote carbon financial trading, promoting commercial law amendment, and promoting the linkage mechanism between specialized environmental justice and carbon finance and other safeguard measures. Finally, improving the carbon finance system is required to promote and protect the orderly development of carbon finance. To promote the reform of the pattern of economic development, the concept of ecological and environmental protection in the financial sector needs to be implemented to form an overall pattern of pollution reduction, carbon reduction and synergistic efficiency improvement.

Despite nearly twenty years of privatization, mixed-ownership reform has been the mainstay of SOE reform in China in recent years. This raises the question of whether the financial performance of mixed-ownership firms (Mixed firms) is better than private-owned enterprises (POEs). Although Mixed firms suffer more from government intervention, unclear property rights, and interest conflicts between state shareholders and private shareholders, they can also benefit from the external resources controlled by the state. Therefore, the performance of Mixed firms is still unclear. Collecting data from the Chinese A-share listed market, we divide the firms into POEs, Mixed firms controlled by the state (MixedSOEs), and Mixed firms controlled by the private sectors (MixedPOEs). Measuring profitability using ROA and ROE, we find that on average, POEs perform better than Mixed firms, and MixedPOEs have a higher profitability than MixedSOEs. Within Mixed firms, more state shares are related to lower profitability, and more private shares are related to higher profitability. Using the NBS survey data, we further find that on average, SOEs exhibit the lowest profitability, with MixedSOEs and MixedPOEs in the middle, and POEs have the highest profitability. We try to address the endogeneity challenge in several ways and get similar results. Overall, our analysis provides new evidence on the financial performance of mixed-ownership firms.

Does large-scale privatization increase income inequality? To answer this question, we analyze the impact of China’s reform of state-owned enterprises on labor market outcomes in urban areas from 1992 to 2004, exploiting cross-prefecture variation in reform exposure stemming from initial differences in the employment shares of urban collective enterprises and state-owned enterprises. Our analysis reveals that workers in prefectures with higher exposure to the reform experienced a more rapid decline in employment and a slower increase in income, compared to those in less exposed areas. Further analysis shows that individuals with lower income and those with lower educational attainment experienced greater losses. A back-of-the-envelope analysis indicates that the reform contributed to more than 40% of the study period’s increase in income inequality.

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.

We examine the impact of bankruptcy court establishment (BCE) on corporate acquisition activities using hand-collected data of city-level BCE in China from 2008 to 2020. The results show that BCE promotes corporate acquisition activities largely due to mitigated information asymmetry and decreased deal inefficiency. Our results highlight the important role of judiciary reform in corporate acquisition decisions in emerging markets.

It remains unclear whether state shareholding (SS) truly enhances firms’ fulfillment of their corporate social responsibility (CSR) or merely motivates them to strategically release “enhanced” CSR reports. Utilizing the reform that permits state–owned equity to participate in privately–owned enterprises (POEs) in China, we find that the participation of SS enhances POEs’ access to resources and alleviates their needs for legitimacy, leading to disparities in CSR disclosure and substantive CSR activities for POEs, consistent with the notion of greenwashing. The greenwashing behavior is particularly pronounced in the presence of large state-owned shareholder and when CSR disclosure is compulsory.
