<p>This study uses the carbon emissions trading schemes (ETS) as a quasi-natural experiment to investigate how market-based environmental regulation influences technology cooperation.

摘要

This study uses the carbon emissions trading schemes (ETS) as a quasi-natural experiment to investigate how market-based environmental regulation influences technology cooperation. Analyzing a dataset from 2008 to 2021, our findings reveal that the carbon ETS policy significantly boosts the strength of intercity technology cooperation. We ensure the robustness of these results through placebo tests, PSM-DID, and by changing the dependent variable. Additionally, the carbon ETS encourages the formation of more technology cooperation partnerships between cities. Notably, when cooperation involves universities and research institutes (URI), the effects are particularly strong in both strength and partnerships. Furthermore, we find that the policy enhances technology cooperation by promoting environmental subsidies, environmental investment, and reducing institutional distance. The impact of carbon ETS is significant within a 250 km range, with URI cooperation strength remaining significant even beyond this distance. The effects of the carbon ETS on technology cooperation also vary depending on the type of city pair involved.
