行为金融学的发展离不开各种心理学理论。大量的心理学研究成果显示，人们在进行实际的投资决策时，其信念的形成并不遵循贝叶斯理性，其选择的偏好也并非满足“理性”的假设，而是存在种种“非理性”的局限。事实上，这种“非理性”成为人们在实际生活中的一种普遍的思维和决策模式，对其决策行为和结果产生总体的和长远的影响，典型的如代表性思维、经验法则、锚定与调整效应、框定依赖偏差、首因效应和近因效应、证实偏差等。本文在介绍这些经典金融心理学理论的同时，予以借鉴并对我国A股市场上发生的投资者心理就行了分析，本文成果对于研究我国证券市场投资者的心理状态具有较强的启迪与借鉴意义。

This work explored the changes in production decision-making trends of Chinese steel enterprises under the influence of the carbon border adjustment mechanism. First, using evolutionary game theory, the interactive mechanism of complex production strategies among steel enterprises considering the carbon border adjustment mechanism was studied, including the impact of government subsidy coefficients, additional profits and carbon tax prices on enterprise decisionmaking.Second, the influence of key parameters on the dynamic evolutionary process was analysed. On this basis, the empirical simulation method was used to verify the game model and the main conclusions. Finally, the sensitivity analysis of the selected parameters was determined using Matlab software. The results showed that additional profits from green investment, government subsidy coefficients, input-output values and carbon tax prices had a higher impact on the evolution of enterprise production strategies. The results of this study provide a decision-making basis for the selection of future production methods for steel enterprises.

Using the firm-level data of the Chinese industrial sector from 1998 to 2010, this study investigates the impact of the previous environmental protection experience of prefecture-level Communist Party secretaries on the COD regulation within the secretaries’ respective jurisdictions. The study finds that the secretaries’ previous environmental protection experience has reduced the COD discharge intensity. The duration of the previous environmental protection experience is selected as an instrumental variable and the endogeneity is further addressed; the research conclusion remains unchanged. However, this negative impact only lasts for two years and presents an unclear long-term impact. The negative effect on COD discharge intensity caused by the previous environmental protection experience is affected by the mandatory regulation pressure from the central government and the overall polluting density of the sub-sectors. Secretaries with previous environmental protection experience do not reduce the COD discharge intensity by using the punishment mechanism of increasing sewage charges. The secretaries, instead, encourage enterprises to use clean production technology, save water resources, and reduce the produced COD level. Also, the secretaries place an emphasis on the treatment of wastewater pollutants, thus reducing the COD discharge intensity. The conclusions of this study can provide decisionmaking reference for the selection and training of local officials, with the goal of environmental regulation.

Overseas compliance management is crucial for multinationals to operate with high character, but existing research has paid little attention to emerging multinationals’ overseas misconduct. Focusing on different directions and the interaction of the institutional gap and aspiration gap, we conducted an empirical analysis of a sample of Chinese multinationals who engaged in outward direct investment from 2009 to 2021 and found that in the case of a negative institutional gap, there is a positive linear correlation between a positive/negative aspiration gap and overseas misconduct. In the case of apositive institutional gap, there is a U-shaped relationship between a positive aspiration gap and overseas misconduct, and an inverted U-shaped relationship between a negative aspiration gap and overseas misconduct. Research conclusions bridge the divergence of the institutional paradox and aspiration paradox, provide a nuanced understanding on overseas misconduct, and distinguish different situations to guide emerging multinationals to operate in compliance overseas.

We examine communication of political connections in corporate China, and show that politically inclined positive words—words in connotation of political sentiment—serve as a distinct and effective signaling device for corporate political connections. Using a large sample of corporate news, we find that news’ political sentiment, instead of orthodox political measures such as occurrences of political nouns and political entities, reflects executives’ political connections for private enterprises, and is related to rent-seeking benefits in government subsidy, tax refund, financing constraints and political risk. Our results demonstrate that political sentiment is an effective way to decode subtle corporate political connections in modern China’s “Mind Politics” environment that infiltrates into private corporations.

Using sample of Chinese listed firms from Q1 2017 to Q4 2022, this article examines the impact of economic policy uncertainty on share repurchases. We find that economic policy uncertainty significantly increases the probability and scale of open market share repurchases. Private enterprises, government-supported enterprises, innovative enterprises, and investment hotspot enterprises repurchased more shares during periods of high economic policy uncertainty. Additionally, the market value of repurchase programs issued during periods of high economic policy uncertainty is larger. We also discover that economic policy uncertainty substantially influences the characteristics, timing, and outcomes of the repurchase programs. Lastly, this article confirms that share repurchase behavior has a similar effect to voluntary disclosures and can alleviate the information asymmetry triggered by economic policy uncertainty. In summary, Chinese listed firms have resorted to more share repurchases during periods of high economic policy uncertainty to convey their actual value and boost investor confidence, aligning with the signaling motive. Open market share repurchases surface as an efficacious instrument to cope with the risk from economic policy uncertainty.

The caliber of export products is a microcosmic reffection of economic development quality. This study seeks to elucidate the inffuence of environmental regulation on product quality, integrating the role of the skill premium as shaped by environmental regulation within a Dixit-Stiglitz CES production function model. Additionally, we empirically scrutinize the interplay between environmental regulation, skill premium, and product quality, utilizing Chinese customs export data in conjunction with data from listed companies spanning 2003-2015. The conclusions drawn from our theoretical analysis and empirical veriffcation reveal an inverted U-shaped relationship between environmental regulation and product quality, which is tempered by the skill premium. Moreover, a signiffcant positive correlation exists between environmental regulation and the skill premium. Similarly, the relationship between the skill premium and product quality manifests an inverted U-shape. Notably, an elevated skill premium markedly bolsters the enhancement of product quality through green innovation. These insights underscore the need for balanced environmental regulations and strategic investment in skilled labor to augment product quality. This serves as a valuable compass for policymakers and businesses endeavoring for green innovation and high-quality, sustainable economic growth.

Based on the matching data of China’s industrial enterprise database and enterprise patent database, this study investigates the effect and mechanism of government subsidy policy on the innovation performance of Chinese enterprises using the panel data matching and multi-period difference-in-difference model. Results show that the incentive effect of government subsidy policy on enterprises’ innovation performance is dominant, thus improving the innovation performance of Chinese manufacturing enterprises. However, the promotion effect on lowquality innovation is greater than that on high-quality innovation. Moreover, the government subsidy policy affects the innovation performance of enterprises by stimulating enterprises to increase their R&D investment, increasing the spending on rent-seeking and taking on more social responsibility. The government subsidy policy significantly affects the innovation performance of non-state-owned enterprises, small and medium-sized enterprises, and technology-intensive industries. The impact of government subsidizing policies varies regionally. The policy effect on enterprise innovation performance is significant in the eastern and central regions but not in the western and northeast regions.

In the process of green transformation of China's economy, it is of great practical significance to study the impact of green finance in supporting the development of the real economy, especially the impact of green credit on enterprise innovation, in order to promote the green transformation of enterprises, industrial structure upgrading and sustainable economic development. This paper takes green credit as a perspective and introduces it into the analytical framework of the impact of environmental regulation on corporate green innovation, through theoretical mechanism analysis and empirical testing, in order to reveal the impact and mechanism of green credit on corporate green innovation. It is found that green credit can effectively promote green innovation in heavy polluting enterprises, and it is mainly reflected in the increase of green utility model patent applications with a low degree of inventiveness. The promotion effect of green credit on green innovation is more obvious in regions with lower levels of economic development. Further mechanism analysis shows that green credit policy promotes green innovation of heavy polluting enterprises mainly through the incentive effect brought by changing financing environment and the pressure effect brought by increasing market competition. The findings of this paper can provide references for policy-making departments, banks and enterprises.

In recent years, the attempt to curb state-owned enterprises (SOEs) has resulted in dedicated rules in trade agreements. This paper reveals significant paradigm shifts in cross-border SOE regulation by exploring the emerging SOE rules and contrasting them with SOE disciplines in WTO agreements. First, the emerging SOE rules shift the emphasis from regulating trade measures to the competitive behaviour of SOEs. More importantly, the emerging SOE rules are characterized by excessive focus on behaviour analysis and a per se approach. Under a per se approach, a violation of the emerging SOE rules could be established regardless of whether the behaviour of an SOE caused a harmful trade or competition effect. Finally, in light of SOE reform in China, the article contends that the emerging SOE rules’ behaviour analysis deviate cross-border SOE regulation from its primary goal of levelling the playing field.
