This paper studies how the carbon emission trading system (ETS) pilot policy announced in 2011 affects firm dynamics, including entry, exit, and innovation. Using a difference-in-difference-in-differences empirical strategy, we find that in pilot cities, in targeted sectors, and after the policy is announced, there are significantly less entry and exit, but more patent applications related to energy efficiency. The positive effects on the patent applications are more pronounced in larger and older firms. The effects of the regulation diffuse in the input-output networks, leading to more patent applications in upstream and downstream sectors. These facts can be rationalized by a firm-dynamics model with input-output linkages. We calibrate the model using simulated method of moments (SMM) and conduct a policy experiment. The positive effects of ETS on growth and welfare are amplified in the presence of input-output networks.

Keywords: emission trading system, firm dynamics, energy efficiency, input-output linkages
