摘要
This study investigates the causal impact of market-based environmental regulation on firm innovation by examining a large-scale market-based regulatory attempt in a developing country, namely, China's sulfur dioxide (SO2) emissions trading program. Based on the panel data of China's publicly traded firms from 2004 to 2015, we adopt the difference-in-differences (DID) model to examine the innovation effects of the SO2 emissions trading pilot policy. The results show that the program leads to a significant increase in patents and environmental patents among regulated firms. And the innovation effects of the policy perform better in areas with a high level of environmental enforcement. In further analysis, we find that the program decreases SO2 emissions and promotes industrial growth in pilot areas. These evidences imply that the market-based emissions trading policy indeed promotes firm innovation and environmental innovation even in the context of a developing country, which is conductive to a win-win situation in both environmental protection and economic growth.
