Encouraging enterprises to engage in green innovation is a potent strategy for reducing carbon emissions from production. As one of the largest carbon emitters, China has launched a series of policies to achieve carbon peaking and neutrality collectively referred to as China's dual carbon policy. However, existing research on the impact of China's dual carbon policy on green innovation by heavy-polluting enterprises is insufficient. To fill this gap, this study constructed a theoretical model to draw hypotheses about the impact of the dual carbon policy on enterprises' green innovation and verified this impact using a difference-in-differences model to conduct a quasi-natural experiment based on data from 2010 to 2022 from Chinese A-share-listed enterprises. The results indicate that the dual carbon policy had a significantly positive influence on green innovation in heavy-polluting enterprises. Moreover, environmental tax mediated this effect, while enterprises' total costs and subsidies positively moderated it. Additionally, the impact exhibited variations based on several key factors, including green patent type, carbon emissions, enterprise ownership structure, and Environmental, Social, and Governance ratings. This study supplements related research on the effects of environmental policy on green innovation and provides both theoretical and empirical support for adapting subsequent environmental policies. • This study explores the impact of China's dual carbon policies on green innovation by firms. • We create a theoretical model and validate it using data from listed Chinese firms. • The dual carbon policies significantly increase green innovation by firms. • This relationship is mediated by environmental tax and moderated by firm costs and subsidies.

This study examines how urban greening policies affect urban ecological resilience through a quasi-natural experimental analysis of various cities in China. Leveraging the country's large-scale promotion of forest city development, we assess the effectiveness of these policies using differences-in-differences modeling across multiple time periods. The results affirm the positive impact of urban greening on resilience, as designated forest cities demonstrated enhanced resilience levels compared to control cities. Notable disparities were also found among the three major Chinese urban agglomerations - the Yangtze River Delta, Pearl River Delta, and Beijing-Tianjin-Hebei regions - in terms of policy effects. While short-term resilience increased under central government oversight, long-term gains relied more on intercity cooperation within agglomerations. It highlights the limitations inherent within China's "experiment under hierarchy" paradigm but also benefits from regional integration. This study contributes novel insights regarding the dynamic relationship between governance structures and urban ecosystem resilience under authoritarian contexts. Innovatively, we explore how intercity cooperation among urban agglomerations affects the long-term effectiveness of urban ecological governance, thereby contributing to a deeper understanding of the complexities involved in fostering resilient urban ecosystems under such governance models. • An evaluation index for urban ecological resilience (UER) was built based on DPSIR framework. • Multi-period DID model was used to analyze the impact of forest city on UER. • Yangtze River Delta had the highest resilience. • National Forest City Certification significantly improved UER of the three megacity clusters.
