Abstract: In recent years, a pressing global challenge has been that increasingly stringent environmental regulations have failed to prevent global climate change. In this context, exploring the synergistic effects of a policy mix approach has emerged as a promising strategy to turn the tide. Given that companies are the primary sources of carbon emissions, this study adopts a novel micro-level perspective. It employs the difference-in-differences method and establishes a two-way fixed effects model to empirically examine the interactive effects of the Low-Carbon City Pilot (LCCP) and the Carbon Emissions Trading Pilot (CETP) on corporate low-carbon development. Based on data availability and relevance, it uses a sample of Chinese listed industrial companies in 2007–2020. The findings indicate that the CETP enhances corporate carbon performance, whereas the LCCP has no significant impact on its own. However, the combined implementation of the two policies has resulted in a synergistic effect, with green innovation playing a mediating role in this process. The study also identifies the presence of a “green paradox” under heavily polluting industries and a weakening of the policies’ effectiveness in Western China and among non-high-tech firms. For emerging countries undergoing low-carbon transitions, it is essential to design context-specific policy combinations that maximize the effectiveness of environmental regulations.
