This study aims to deeply analyze the mechanism by which the issuance of green bonds affects the ESG evaluation of enterprises. Using the sample of Chinese A-share listed companies from 2014 to 2023, the dual difference method was employed to empirically analyze the impact of green bond issuance on the ESG performance of companies and its mechanism. The study found: Firstly, compared with enterprises that issue ordinary bonds, the issuance of green bonds significantly improved the ESG rating of enterprises. This conclusion remained robust even after controlling for endogeneity issues and replacing variables. Secondly, the mechanism test indicated that green bonds indirectly improved the ESG performance of enterprises through three paths: enhancing information disclosure transparency, reducing agency costs, and promoting green innovation. Thirdly, the heterogeneity analysis showed that the promotion effect of green bonds on ESG was more significant in non-state-owned enterprises, heavy-polluting industries, and enterprises in the eastern region. This study not only enriches the theoretical system of green finance and enterprise sustainable development, but also provides empirical evidence for policy makers to guide enterprises to optimize ESG practices through green bond financing.

This paper explores how regional innovation ecosystems support the growth of technology startups, using Hangzhou's "Six Little Dragons" as a case study. Drawing on innovation ecosystem theory, regional innovation systems, and new trade theory, the study analyzes how talent, capital, and industrial coordination jointly shape firm development. The paper identifies three key mechanisms: sustained talent attraction and knowledge spillovers anchored in universities and research institutions; a full-lifecycle financial support system characterized by a "patient government" and patient capital that mitigates early-stage market failures; and industrial chain coordination combined with scenario-based innovation that accelerates technology validation and market entry. The findings suggest that the success of Hangzhou's technology firms stems from systematic ecosystem interactions rather than isolated firm-level advantages, offering policy-relevant insights for enhancing regional innovation capacity in other cities.

This study empirically analyzes the impact of supply chain digitalization on the total factor productivity of enterprises. Research has found that the digitalization of the supply chain has enhanced the total factor productivity of enterprises and has undergone a series of robustness tests. Mechanism analysis indicates that the efficiency of enterprise resource allocation and enterprise innovation input can further positively regulate the promoting effect of supply chain digitalization on the total factor productivity of enterprises. Heterogeneity analysis indicates that for private enterprises and those without significant deficiencies, the positive impact of supply chain digitalization on the total factor productivity of enterprises is more significant, while for state-owned enterprises and those with significant deficiencies, this impact effect is not significant.
