题目：Does Environmental Regulation Spur Environment-Friendly Technology Change? Evidence from a Quasi-natural Experiment in China

内容摘要： This paper investigates whether environmental regulation spurs environmental-friendly technology change. To identify the causal effect, we use a difference-in-differences strategy by exploiting a quasi-natural experiment in China, that is, the Two Control Zones (TCZ) policy implemented by the Chinese government in 1998, in which tougher environmental regulations were imposed in TCZ counties than in non-TCZ counties. We find that stringent environmental regulation increases regional green innovation by 18.6%, but does not crowd out other innovation activities. Our instrumental variable estimation confirms that this impact is causal. We further find that this impact is mainly driven by private firms and work through two potential mechanisms -- enterprises’ energy-saving and environment-protecting responses to the regulation.
