碳交易政策对高耗能企业绿色创新影响研究

With the intensification of global warming trends, carbon trading policies, as a key market-based tool for addressing climate change, play a significant role in advancing China\'s "dual carbon" goals. Energy-intensive enterprises, being the primary emitters of carbon, have their green innovation capabilities serving as crucial evaluation metrics for policy effectiveness. Current research has focused on the macroeconomic regulatory and industrial restructuring impacts of carbon trading policies at the macro level, as well as the influence of cost changes on corporate performance. By reviewing relevant literature and integrating the theoretical foundations of carbon trading policies and green innovation in energy-intensive enterprises, this study aims to provide a comprehensive background and theoretical support for further in-depth research, thereby contributing to policy refinement and corporate sustainable development.To investigate the impact of carbon trading policies on green innovation in energy-intensive enterprises, this study employs a combination of theoretical analysis and empirical testing. Data from 271 energy-intensive enterprises spanning 2000-2023 were selected for analysis using a difference-in-differences model. The results indicate that carbon trading policies significantly promote green innovation in these enterprises, with a notable increase in green patent applications. Factors such as firm size and asset-liability ratios moderate the policy effects, with larger enterprises benefiting more substantially. Regional disparities also play a role, as enterprises in key import-export provinces and municipalities are more significantly influenced by carbon trading policies.
