摘要
基于2011—2020年中国地级市面板数据,运用多种计量方法探究了数字经济对绿色全要素生产率具的影响及作用机制。研究发现,数字经济对绿色全要素生产率具有显著正向影响,主要推动绿色技术进步。产业结构升级和要素配置扭曲缓解在其中发挥中介作用。数字经济是资源型城市打破“资源诅咒”的关键因素,但数字经济发展不均衡会导致中心城市与外围城市存在“数字鸿沟”。从时间效应来看,产业数字化和数字产业化等数字经济细分维度的发展是绿色全要素生产率提升的持久动力。最后,基于DID模型评估政策效应表明,数字化经济政策也有利于提升绿色全要素生产率。
Based on the panel data of prefecture-level cities in China from 2011 to 2020,this paper uses various measurement methods to explore the impact and mechanism of the digital economy on green total factor productivity. Result finds that the digital economy has a significant positive impact on green total factor productivity, mainly promoting green technology progress. The upgrading of industrial structure and the alleviation of element misallocation play a mediating role. The digital economy is a key factor in breaking the “resource curse” in resource-based cities, but the uneven development of the digital economy can lead to a “digital divide” between central and peripheral cities. From the perspective of time effect, the development of digital economy segmentation dimensions such as industrial digitization and digital industrialization is a lasting driving force for the improvement of green total factor productivity. Finally, the evaluation of policy effects based on the DID model indicates that digital economic policies are also conducive to improving green total factor productivity.
