摘  要: 基于空间视角,利用2008—2019年中国278个地级市的面板数据,运用空间杜宾模型和面板门槛模型,实证检验技术创新对能源效率的直接效应、间接效应及门槛效应。研究表明:技术创新不仅有利于提升本城市的能源利用效率,还会通过溢出效应提升邻近城市的能源利用效率,存在显著的空间溢出效应,并且技术创新对能源利用效率的影响因城市区位和技术创新水平不同而存在异质性。绿色技术进步和产业结构升级在技术创新提升能源利用效率中发挥中介作用,技术创新通过提高绿色技术进步和促进产业结构升级来提升能源利用效率。当经济发展水平较低时,技术创新对能源利用效率有明显的抑制作用;当经济发展水平越过一定临界值后,技术创新能显著提升能源利用效率。

Abstract: Based on the spatial perspective, using the panel data of 278 prefecture-level cities in China from 2008 to 2019, and adopting the spatial Durbin model and panel threshold model, the article empirically tests the direct, indirect and threshold effects of technological innovation on energy efficiency. The research shows that technological innovation is not only conducive to improving the energy use efficiency of the local city, but also improves the energy use efficiency of neighboring cities through spillover effect with spatial spillover effect. It also finds that there exists significant spatial spillover effect, and that the impact of technological innovation on energy use efficiency is heterogeneous due to different urban locations and technological innovation levels. Green technology progress and industrial structure upgrading play an intermediary role in technological innovation to improve energy use efficiency, and technological innovation improves energy use efficiency by improving green technology progress and promoting industrial structure upgrading. When the level of economic development is low, technological innovation has an obvious inhibitory effect on energy utilization efficiency. When the level of economic development exceeds a certain critical value, technological innovation can significantly improve energy utilization efficiency.
 
Key words: technological innovation; energy efficiency; economic development level; spatial Durbin model
