随着气候变化的加剧,气候政策在中国经济系统中发挥着越来越重要的作用。现有文献已经关注到气候物理风险对企业生产率的影响,但较少考察政策维度的气候风险即气候政策不确定性对企业生产率的影响。基于此,文章构建了公司层面的气候政策不确定性指数,并考察了其对企业全要素生产率的影响效应和作用机理。研究表明,气候政策不确定性会诱发企业升级困境,显著抑制企业全要素生产率提升。气候政策不确定性指数每上升 1 个标准差,全要素生产率下降约5.2% 个标准差。机制分析表明,气候政策不确定性会挤出实体投资和绿色创新投资,挤入金融投资,从而抑制企业全要素生产率提升。异质性分析表明,气候政策不确定性的影响在风险传导较强、风险应对较差以及政策引导比较薄弱的企业中更加显著。经济后果分析表明,气候政策不确定性所导致的企业升级困境会弱化其市场竞争力和价值链话语权。文章研究表明,政府应关注气候政策不确定性问题,通过营造更加稳定的气候政策预期来缓解企业升级困境。

This paper models the effect of corporate information preference on stock return volatility based on optimization problems of information decisions for firms and investors. Our model hypothesizes a positive correlation between corporate information preference and volatility. Utilizing the ideal institutional background of the Chinese stock market, we empirically confirm that corporate information preference has a positive impact on volatility, particularly for firms facing more severe financial distress, limited investor attention, and fewer analyst coverage. Our study provides a new perspective for analyzing the interaction between information supply and asset price dynamics.

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.

Using a comprehensive factor zoo, we document a notable factor MAX premium in the Chinese market. Factors with high maximum daily returns consistently outperform those with low maximum returns by 0.82% per month in the future, on a risk-adjusted basis. This premium remains robust controlling for various factor characteristics, and is not sensitive to the selection of factors. The factor MAX anomaly stands apart from lottery-type stock anomalies and contributes to elucidate most of these anomalies. The factor MAX premium concentrates in high-eigenvalue principal component factors, shedding light on the prevalent lottery preferences for factor investing in China’s A-share market.

为规范证券市场，证监会发布《关于严格执行退市制度的意见》。但退市后如何持续保护中小投资者权益，在具体实践过程中仍存在一些盲点。本文以山东航空股份有限公司修改公司章程为例，探讨上市公司退市后关于规章制度的一些盲点。具体如下：第一，修改公司章程中与大股东的关联交易时，并未明确指出大股东及其关联方是否应该回避表决。实践中，山东航空股份有限公司的控股股东及其关联方并未回避，导致修改公司章程中关联交易议案通过。第二，退市公司关联交易比例并无明确规定，由此可能导致关联交易比例过大。第三，控股股东利用自己绝对控股地位，否决中小股东合理提案。作者认为，针对本文提到的盲点，监管部门必须出台明确规定大股东及关联方在修改公司章程时应回避事项，而且还要明确规定关联交易的上限，持续保护退市后中小投资者权益。

Using official information published by Central Commission for Discipline Inspection (CCDI) of the CPC, we construct a database of officials who have been found guilty of corruption in China in the period 2012-21 with their personal characteristics and the amount of embezzled funds. We use it to investigate the correlates of corruption, estimate the effects of corruption on inequality, and find the expected increase in officials’ income due to corruption and the gain in income distribution ranking. We find that the amount of corruption is positively associated with education, administrative (hierarchical) level of the official, and years of membership in the Communist Party. The sample of corrupt officials belongs to the upper income ranges of Chinese income distribution even without corruption. But corruption is a significant engine of upward mobility. While only one-half of the corrupt official would be in the top 5 percent of urban distribution without illegal incomes, practically all are in the top 5 percent when corrupt income is included.

In the context of promoting high-quality economic development, using digital technology to empower industrial transformation and upgrading, thus driving consumption growth has become a key problem that needs to be solved urgently. By using data at the prefecture-level cities in China from 2011 to 2020, the paper has discussed the influence of the digital economy on residents' consumption and its internal mechanism. Theoretical analysis and empirical test results have shown that first of all, the digital economy has significantly improved residents' consumption, and this conclusion is still valid after the endogenous test and robustness test. Secondly, mechanism analysis has shown that the digital economy can increase residents' consumption by promoting the upgrading of the industrial structure. Thirdly, the promotion effect of the digital economy on residents' consumption is heterogeneous between urban and rural areas and between different regions. Compared with urban, and eastern and central regions, the digital economy has a more significant incentive for residents' consumption in rural areas and western regions, indicating that its development is beneficial to narrowing the gap of consumption between urban and rural areas and between regions. Finally, the improvement effect of the digital economy on residents' consumption has marginal increment nonlinear characteristics, which is continuously strengthened with the upgrading of industrial structure. The above research conclusions can provide a theoretical basis for further improving the infrastructure of the digital economy, accelerating the integration of the digital economy with traditional industries, and building a consumer Internet.

This study documents how the political hierarchy plays a significant role in determining corporate environmental governance. By conducting difference-in-differences analysis to investigate listed firms in China, this study demonstrates that local and central SOEs headquartered in jurisdictions far removed from central government supervision have worse environmental governance than POEs. Verticalization reforms implemented in 2016 enable provincial environmental protection bureaus to direct lower-level bureaus. Local governments cannot control environmental protection bureau leaders for economic development. This study finds that the corporate environmental governance of local SOEs has significantly improved following the reform, as local environmental protection bureaus no longer have conflicts of interest with local governments. However, the reform has not resulted in improvements to corporate environmental governance in central SOEs, whose executives occupy higher status than provincial Environmental Protection Bureau leaders, nor in POEs, which were already managed before the reform. Further evidence indicates that local SOEs experience an increase in abatement investments and relationship building expenses following the reform. Lastly, our study reveals that verticalization reform costs are negligible. Local SOEs have not experienced a decline in financial performance or corporate valuation. This study suggests that policymakers should consider the political ranking of government agencies and enterprises to improve environmental governance.

The study of interconnections between various sectors of the national economy is crucial for understanding the pattern and pace of macroeconomic growth. This paper analyzes the macroeconomic impact of shocks occurring in specific sectors through both supply and demand perspectives and proposes a combination of bottom-up and top-down structural path analysis approaches to trace the transmission path of network spillover effects, where shocks in this paper refer to microeconomic productivity changes and network spillover is defined as the effect on GDP due to the propagation of shocks to other sectors. The research results found that the total spillover effect of primary and secondary industry sectors in China shows an inverted U-shape, and the total spillover effect of tertiary industry sectors shows an upward trend. A large total spillover effect of a sector does not mean that both upward and downward spillover effects are large; for example, the construction industry has high upward spillover effects and low downward spillover effects. The spillover effect of each production layer decreases as the path lengthens, and the distribution is Lshaped.In addition, by identifying the critical paths of spillover effects, we find that the spillover effects of labor-intensive industries, such as wholesale and retail, are decreasing year by year, and the spillover effects of the paths related to the information technology industry are gradually occupying an important position.
