Copper resources are widely used in power networks and clean - energy tech like PV panels, wind turbines, and NEVs. Restricted by domestic resources, China's copper supply chain is vulnerable with risks. Based on six supply - chain stages, this paper builds an assessment system for China's copper supply - chain risks. By adopting an improved Benefit of Doubt (BOD) model, this paper has systematically evaluated the risks in the whole copper supply chain, revealing the trends and deep-rooted causes of these risks. The findings of this study reveal that: (1) The supply chain risk of China's copper resources presents a significant upward trend over the past 15 years; (2) The current supply chain risks in copper are mainly concentrated at the stages of import, production, and application; and the recycling risk has a great potential for reducing the copper supply chain risks in the future. Based on these findings, this paper proposes two policy recommendations: (1) Develop diversified channels for importing copper resources and optimize overseas investment patterns and; (2) Improve the domestic supply capacity of secondary copper resources and reduce the risks at the recycling stage.

This paper explores the impact of Confucian culture on the environmental management practices of firms, utilizing data from A-share listed companies in China from 2009 to 2022. The study reveals several significant findings: (1) Firms in regions with a stronger presence of Confucian culture are more likely to adopt environmentally responsible management practices; (2) Confucian culture enhances firms' environmental management through three channels: promoting innovation, easing financing constraints, and reducing managerial myopia, with particular emphasis on alleviating financing constraints; (3) Regional environmental regulations mitigate the positive influence of Confucian culture on firms' environmental management practices. This study contributes to the literature by elucidating the determinants of corporate environmental management and emphasizing the critical role of cultural factors, particularly in overcoming financial barriers, in corporate decision-making.

This paper constructs an evaluation index system for the high-quality development of the marine economy based on the five dimensions of the new development paradigm. It employs entropy method, kernel density analysis, and Dagum Gini coefficient method to analyze the high-quality development level of China's marine economy and its spatial-temporal evolution from 2013 to 2022. The findings reveal that: (1) The comprehensive index for the high-quality development of China's marine economy exhibits an overall fluctuating upward trend; (2) The high-quality development levels of the marine economy in the eastern and southern marine economic circles are both above the national average, while that in the northern marine economic circle is below the national average; (3) The focus of high-quality development in China's marine economy is shifting towards economically developed regions along the southeast coast, demonstrating a trend of "higher in the south and lower in the north." Moreover, the gap in high-quality development of the marine economy among the three major marine economic circles is gradually narrowing, and the high-quality development of regional marine economies tends to become more coordinated.

The disparities in green transition have led to the call for a ‘just transition’. However, the large differences in energy efficiency across different regions have been identified as a primary hazard to the just transition. This study examines whether transferring low-carbon technology can improve the efficiency of energy, enhancing the overall energy efficiency, and marketing a sustainable and equitable energy future. In this paper, we utilize the Undesirable-SE-SBM model to estimate the energy efficiency of China's 30 provinces during 2012 to 2022, and empirically tested the impact of low-carbon technology transfer on the convergence of total-factor energy efficiency by convergence analysis. The results showed that: (1) There is evidence of σ convergence and absolute β convergence in the eastern and western regions, but not in the central region. (2) Low-carbon technology transfer can accelerate the convergence of total factor energy efficiency. Lagging regions that adopt low-carbon technologies can catch up with the advanced regions' level of total-factor energy efficiency. (3) There is regional heterogeneity in the effect of low-carbon technology transfer on the accelerating convergence of total factor energy efficiency. The western region experiences the most significant acceleration, followed by the eastern and central regions.

Trust can be obtained by firm location (endowed trust) or behaviors (earned trust). We are interested in whether firms located in trusted regions are more likely to protect stakeholders’ benefits as a strategy to earn trust. Based on a sample of Chinese firms, we find a significant and positive correlation between regional endowed trust and local firms’ environmental and social commitment. We suggest that endowed trust has two effects: 1) shaping local firms’ legal cognition and thus decreasing misconducts; and 2) providing resources and thus mitigating financial constraints, both of which encourage firms to protect the environment and society. Moreover, the positive effect of high endowed trust is weakened when corporate governance or local legal environment is strong.

The discussion on the innovative effects of intellectual property pledge financing is a mainstream trend. In this context, this study has improved the existing research from several aspects, such as broadening the dimensions of innovation, adding dynamic analysis, refining multidimensional mediation mechanisms, and employing unique samples. Ultimately, we come to the following conclusions: (1) Intellectual property pledge financing suppresses enterprise innovation, especially innovation quality, but this pattern will be broken by raising the threshold of innovation conditions. The reason is that strict innovation conditions can lead to a poor innovation foundation for enterprises, which are rarely affected by the fluctuation of funds obtained from intellectual property pledge financing. (2) Intellectual property pledge financing has a non-linear effect on firm innovation, characterized by an increase followed by a decrease, suggesting that intellectual property pledge financing in current China can only provide a temporary stimulus for firm innovation. (3) The relationship between intellectual property pledge financing and enterprise innovation is strongly moderated by the ownership, type, and size of the enterprise, with the inhibitory effect of intellectual property pledge financing on enterprise innovation occurring mainly in state-owned enterprises, high-tech enterprises, and small enterprises, while its positive effects are more pronounced in private enterprises, non-high-tech enterprises, and medium-sized enterprises. (4) Financing constraints, internal incentives, external supervision, and signaling mechanisms are indeed key pathways through which intellectual property pledge financing affects firm innovation, especially when we analyse these mechanisms using dynamic models.

Based on the sample of Chinese A-listed firms from 2003 to 2020, this paper investigates the effect of common institutional ownership on labor income share. The result shows that common institutional ownership can significantly increase firms’ labor income share. Mechanism tests indicate that common ownership can: 1) alleviate financial constraints by reducing the debt financing costs and increasing the trade credit financing, thus increasing the labor income share; 2) improve corporate innovation and therefore enhances the demand for highly-skilled labor, which eventually boost labor income share. Competitive hypothesis test represents that common institutional ownership can reduce the monopoly power of enterprises and decrease monopoly rent, so as to increase the proportion of labor in the distribution. Further analyses present that the network formed by the common ownership can effectively exert the financing support role of SOEs and the knowledge spillover effect of innovative-advantage firms, which contributes to the labor income share increasing of other related firms in the network connection. This study not only enriches the economic consequences of common institutional ownership, but also provides policy guidance for the government to further optimize the income-distribution pattern by deepening the reform of the financial market.

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.

Using unique account-level data from a leading Chinese fintech platform, we investigate how financial influencers, the key information intermediaries in social finance, attract followers through a process of social transmission bias. We document a robust performance-following pattern wherein retail investors overextrapolate influencers’ past returns rather than rational learning in the social network from their past performance. The transmission bias is amplified by two mechanisms: (1) influencers’ active social engagement and (2) their index fund-heavy portfolios. Evidence further reveals influencers’self-enhancing reporting through selective performance disclosure. Crucially, the dynamics ultimately increase risk exposure and impair returns for follower investors.
