用能权交易制度是中国基于源头控制而实施的市场型环境规制政策,引入用能权交易制度对于促进能源技术知识的流动和实现能耗总量与强度“双控”目标具有重要意义。文章以用能权交易试点作为切入点,基于2006~2019年全国256个地级市的面板数据,以专利信息反映能源技术知识流动,采用双重差分法实证检验用能权交易制度对能源技术知识流动的效果及影响因素。研究发现:用能权交易制度能够在总体上有效促进能源技术知识流动。进一步的分析发现,试点城市更高水平的人力资本有助于强化城市试点政策的促进作用。且在东中部地区、一、二线和非资源型城市,政策效果更加明显。The energy rights trading system is a market-based environmental regulation policy implemented by China to control energy consumption at the source. Introducing this system is significant for promoting the flow of energy technology knowledge and achieving the dual control targets of total energy consumption and intensity. This paper uses the energy trading pilot as a starting point, based on panel data from 256 prefecture-level cities across China from 2006 to 2019. It uses patent information to reflect the flow of energy technology knowledge and employs the difference-in-differences method to empirically test the effects and influencing factors of the energy rights trading system on the flow of energy technology knowledge. The study finds that the energy rights trading system effectively promotes the flow of energy technology knowledge overall. Further analysis reveals that higher levels of human capital in pilot cities help strengthen the policy’s promoting effect. The policy effects are more significant in the eastern and central regions, first- and second-tier cities, and non-resource-based cities.
