摘　　要：在理论分析的基础上,从数字基础设施、数字经济普及程度、网络信息资源和数字经济环境与效果四个维度构建衡量数字经济发展的综合指标体系,采用时序全局主成分分析法对2006—2019年中国省际数字经济发展水平进行测算,并运用两阶段最小二乘法和面板门槛模型等多种计量方法考察了数字经济对绿色全要素生产率(TFP)的影响。研究发现:数字经济显著促进了中国绿色TFP的提升,从而从绿色生产率的视角验证了数字经济完全可以成为支撑新发展阶段下中国绿色TFP提升的新力量,这一研究结论在经过一系列稳健性检验后依然成立;作用机制发现,数字经济可以通过激励企业增加研发投入和促进产业结构的优化升级等渠道来促进绿色TFP的提升;在数字经济发展水平较高、地区知识产权保护强度较高的情况下,数字经济的绿色生产率增长效应更为突出;进一步研究发现,与东部地区相比,中西部地区数字经济发展水平的提高对绿色TFP具有更为明显的积极影响。这一研究不仅为评估数字经济的影响效果提供了实证依据,也为依托数字经济推动国内绿色转型发展提供了有益借鉴。Based on theoretical analysis,this paper constructs a comprehensive index system to measure the development of digital economy from four dimensions:digital infrastructure,digital economy penetration,network information resources,and digital economy environment and effects,and uses the time-serial generalization principal component analysis method to measure the provincial digital economy development level index of China from 2006 to 2019,and establishes two-stage least squares method and panel threshold model to analyze the relationship between digital economy and green total factor productivity.The study finds that the digital economy significantly promoted to the improvement of China s green TFP,become a new driving force to support China s green TFP improvement in the new development stage,and this research conclusion is still robust after a series of robustness tests.The mechanism of action finds that the digital economy can promote to green TFP growth by stimulating enterprises to increase R&D investment and promoting the optimization and upgrading of industrial structure.The green productivity growth effect of the digital economy is further enhanced by the higher level of digital economy development and the higher intensity of regional IPR.Compared with the eastern region,the increase in the level of digital economy development in the central and western regions has a more obvious positive impact on green TFP.Our research not only provides an empirical basis for assessing the impact of the digital economy,but also theoretical references for promoting the development of domestic green transformation through the digital economy.
