We use the event study method to assess the impact of China's National Centralized Drug Procurement (NCDP) policy on the stock price of A-share listed companies in pharmaceutical industry. And the empirical evidence reveals that the policy has a negative effect on the share prices of firms won the bids in the past six centralized procurement. The stock prices of winning bidders were more negatively affected than those of non-winning bidders. If the winning bid price continues to be depressed, we cannot rule out the possibility of a collective abandonment of bidding by quality manufacturers.

本文首次对我国 2019 年新证券法生效前的内幕交易案件进行了一个全面和深入的实证研究，并与境外法域进行比较，揭示我国内幕交易法律的执行情况。我国对内幕交易的打击力度持续加大，案件数量显著增长，以行政处罚为主，但 2008 年后刑事处罚逐渐增加。内幕交易变得更为隐蔽，体现在非传统类型的内幕人增多、内幕信息主要与并购相关、选择只交易且利用他人账户交易等。我国的内幕交易处罚类型与境外法域基本接轨，处罚强度甚至居于前列，其主要的影响因素包括违法所得、社会影响、减轻处罚情节、是否使用他人账户等。基于这些发现，本文评价了 2019 年证券法相关修订，提出了相关完善建议，并指出了需要进一步研究的课题。

This paper empirically evaluates the impact of a Government-Initiated Non-Profit Ecommerce Platform (GNEP) on specialty agricultural sales, focusing specifically on Pu’er tea in China. Using a difference-in-differences methodology and a comprehensive panel dataset that covers over 90% of local tea farmers, we uncover a marked substitution effect. The implementation of GNEP leads to an average decline of 11.22% in offline household sales, while online sales see an uptick of 16.88%. Further analysis confirms a universal channel shift from offline to online sales, irrespective of both production levels and tea quality. Contrary to expectations, the overall tea sales volume remains largely stable post-launch. Additionally, premium-quality teas experience a 2.42% price boost online, while regular teas show a 0.40% decrease compared to offline prices. Mechanism analyses further indicate that the increase in online sales is driven primarily by the intensive margin instead of the extensive margin. Although the platform does not significantly expand the number of farmers engaging in online sales, it succeeds in offering a cost-effective avenue for diversifying product offerings and achieving higher prices for premium-quality products. Our study illuminates the transformative role of e-commerce platforms in rural economic development and provides essential insights for policymakers and practitioners.

How much value has been lost in the Chinese bankruptcy system due to excessive liquidation of companies whose going concern value is greater than the liquidation value? I compile new judiciary bankruptcy auction data covering all bankruptcy asset sales from 2017 to 2022 in China. I estimate the valuation of the asset for both the final buyer and creditor through the revealed preference method using an auction model. On average, excessive liquidation results in a 13.5% welfare loss. However, solely considering the liquidation process, an 8% welfare gain is derived from selling the asset without transferring it to the creditors. Firms that are (1) larger in total asset size, (2) have less information disclosure, (3) have less access to the financial market, and (4) possess a higher fraction of intangible assets are more vulnerable to such welfare loss. Overall, this paper suggests that policies promoting bankruptcy reorganization by introducing distressed investors who target larger bankruptcy firms suffering more from information asymmetry will significantly enhance welfare in the Chinese bankruptcy market.

In this paper, we introduce the first dataset that records the news co-mention relationships in the Chinese A-share market. In total, we collected 1,138,247 pieces of news articles that at least mentioned one listed firm in the A market from major Chinese media and financial websites from September 1999 to December 2022. The development of this dataset could enable data scientists and financial economists to investigate the network of stocks through news co-mention in the Chinese stock market. The dataset could also help to construct novel portfolio strategies like the cross-firm momentum strategy with news-implied links as in Ge et al. (2023).

Efficient enterprise development plays a crucial role in the achievement of economic efficiency, which is reflected in the improvement of total factor productivity (TFP). This study examines the effect of corporate maturity mismatch on TFP and explores whether financialisation influences this relationship. This study uses data from Chinese A-share listed non-financial enterprises from 2007 to 2019. We find that maturity mismatch negatively impacts TFP through performance inhibition, agency costs, and capital allocation efficiency reduction. Additionally, we find that financialisation positively moderates the negative effect of corporate maturity mismatch on TFP, and the effect is more pronounced when a firm has higher risk-bearing capacity and greater governance efficiency. We use two-stage least squares to demonstrate the robustness of our results.

High-bargaining-power (low-bargaining-power) customer (supplier) firms borrow (lend) more trade credit according to the literature. We study whether this bargaining power effect strengthens or weakens when the credit supply tightens. We construct a Nash bargaining model of trade credit and show that the bargaining power effect weakens if their financing costs increase more than that of the customers. We find support for our theory using a unique database of listed firms in China that discloses firms’ transaction information with important customers and suppliers. Interest-rate sensitive suppliers, proxied by a non-state ownership, a high debt rollover risk, and a high financial constraint index, reduce trade credit to their high-bargaining-power customers during credit contractions.

In the international context of the surging tide of anti-globalization, China will raise the establishment of pilot free trade zone as a national strategy, and achieve the goal of promoting highquality economic growth through a series of reform measures, such as promoting investment liberalization and facilitation, improving investment promotion and protection mechanisms, and improving the level of overseas investment cooperation. To study the role of the pilot free trade zones on investment, the panel data of 46 cities from 2005 to 2018 are used to empirically test the investment growth effect and investment spillover effect of the pilot free trade zones by using the Difference-in-Differences Spatial Dubin Model. The results show that the pilot free trade zones can significantly promote investment growth and have a spillover effect on investment in surrounding areas. Through the grouping regression of the eastern, central, and western regions, it is found that the eastern pilot free trade zones have the most obvious investment spillover effect on the surrounding areas, and the central pilot free trade zones have a siphon effect on the investment in the surrounding areas. In addition, different batches of pilot free trade zones or the same batch of pilot free trade zones have different investment spillover effects on surrounding areas at different time points. Finally, policy suggestions are put forward: strengthen the strategic implementation of the pilot free trade zones, improve the spatial radiation mechanism, promote linkage development and differentiated development, and make the pilot free trade zones better promote investment growth and investment spillover.

This study investigates the relationship between ESG (environmental, social, and governance) ratings and labor share at the firm level. Using data from Chinese A-share listed firms from 2011 to 2021, we find a significantly positive relationship between the two. Furthermore, we document that state-owned enterprises do not demonstrate a strong sense of political and social responsibility in their employee recruitment projects, while companies with high ESG ratings in East China could increase their labor share due to less stringent financial constraints. Finally, the employment-creation effect of ESG ratings is one of the important channels for improving labor share. Considering the increasing awareness of ESG concepts and the boom in ESG investing, our findings hold significant relevance for employees, directors, investors, and public policymakers.

This study investigates the effectiveness of the volatility-timing strategy in the Chinese equity market. We find that the volatility-managed portfolio (VMP) consistently outperforms its original counterpart, both in individual factor analysis and mean-variance efficient multifactor assessment, and the results are robust in outof-sample setup. Notably, the outperformance is mostly driven by stocks with high arbitrage risk, short-selling constraints, relatively smaller size, and lottery preferences. Further, the multifactor portfolio constructed from the volatility-managed strategy outperforms other portfolios especially in turmoil periods such as high sentiment and low macroeconomic confidence periods. Our findings suggest that in the Chinese equity market with typical trading frictions, volatility timing strategies consistently gain profitable performance.
