In this VUCA era, investigating the impact of supply chain concentration on enterprise resilience holds significant theoretical and practical value. Using panel data from Chinese A-share listed companies (2012–2024), we find that high supply chain concentration significantly undermines enterprise resilience, and the conclusion remains robust after a series of robustness tests and endogeneity treatments. Mechanism analysis shows that financing constraints, innovation capability, and risk-taking act as important mediating channels. Furthermore, nonlinear analysis identifies structural dual-threshold effects associated with industry competition intensity and business environment quality, suggesting that the adverse effect of supply chain concentration on enterprise resilience varies across different threshold intervals. Heterogeneity analysis further shows that this negative impact is more pronounced in enterprises with weak internal management, low levels of digitalization, or excessive ESG greenwashing, as well as in external contexts such as less-developed regions, low regional data factorization levels, or non-high-tech industries. This study provides micro-level empirical evidence for understanding the strategic trade-off between supply chain structure and enterprise resilience and provides a reference for policy makers to improve the resilience and security of industrial chains.

Macroprudential policy, as an important instrument for counter-cyclical regulation, plays a crucial role in enhancing urban economic resilience. Based on this, this paper empirically examines the influence of macroprudential policy on urban economic resilience and its optimization paths using data from 284 prefecture-level cities in China from 2011 to 2023. The research findings indicate that macroprudential policy significantly enhances urban economic resilience, and the conclusion still holds after various robustness tests. Further analysis reveals that the main transmission channels include stimulating digital finance development, promoting industrial structure upgrading, and deepening regional integration. Notably, this effect is particularly pronounced in smart cities, big data pilot zones, and cities with less fiscal pressure. Additionally, the test results of spatial spillover effects show that the direct effect of macroprudential policy on the economic resilience of cities is relatively significant, while the indirect effect is relatively weak. Finally, empirical tests have proved that the improvement of urban economic resilience can further drive regional innovation capability. This study provides empirical support and theoretical references for improving China’s “dual-pillar” regulatory framework and enhancing urban economic resilience.

In order to clarify the evolution characteristics and direction of urban energy performance concepts, reveal the research dimensions, determine the performance results and differences, and clarify the reference benchmark, this study depicts the main systems involved in the process of urban energy utilization, demonstrates their relevance guided by the system view, and proposes the measurement indicators in the economic, environmental, and well-being dimensions. The measurement model of each dimension is constructed using the corresponding models of Data Envelopment Analysis. Taking 142 prefecture level cities in China as examples, the energy performance in different dimensions is measured and compared. The energy performance levels are close in the economic and environmental dimensions. However, the results of the well-being dimension are different from these first two dimensions, and the performance levels among cities differ more. In the economic, environmental, and well-being dimension, 22, 28 and 16 cities have reached the effective frontier, respectively, and the performance benchmark cities of 15, 15 and 5 provinces are non-provincial capital cities, respectively. Based on the above analysis, the “chain” framework evolution direction of concept and measurement is proposed, and this study provides benchmarks and policy suggestions to improve energy performance.

As an important part of improving the socialist market economic system, the social credit system focuses on the market’s micro behavior, which emphasizes the credit self-discipline of enterprises in financial management and checks the orientation for enterprises’ investment decisions. This study selected Shanghai and Shenzhen A-share listed companies for 2012–2023 as samples and used the pilot reform of China’s social credit system as a quasi-natural experiment to test the impact and mechanisms of the construction of the social credit system on enterprises’ overinvestment. The main findings show that the social credit system construction alleviates enterprises’ overinvestment behaviors, realized by the inhibiting effect of internal controls, the reverse effect of risk monitoring, and the guiding effect of business environment optimization. Heterogeneity analyses illustrate that the social credit system construction has a more obvious inhibitory effect on overinvestment for enterprises that are less subject to financing constraints, have higher internet penetration, have better financial development levels, are eastern, non-manufacturing, and large-scale. The conclusions provide new perspectives and references for the government and enterprises to re-examine the economic effects of the social credit system construction, which can promote capital usage efficiency and guide enterprises toward rational management.
