Research on the Nonlinear Impact of Digital Economy on Green Innovation Efficiency in Chinese Provinces
The development of digital economy relies on digital information technology,and with the con-tinuous expansion of its application depth and coverage,it promotes the transformation of various production factors into data resources,effectively reducing production costs and production pollution,and has an in-creasing impact on China's green innovation ability.Based on the GML index of EBM model,this paper cal-culates the green innovation efficiency of various regions in China,and uses panel Tobit model,threshold re-gression model and LightGBM model to explore the impact of digital economy on green innovation effi-ciency.The results show that:the digital economy empowers green innovation efficiency,and both China's digital economy and green innovation efficiency are steadily growing.The digital economy has non-linear ef-fects and single threshold effects on green innovation efficiency.Therefore,it is necessary to strengthen the top-level design of digital economy,optimize the development environment of digital industry,strengthen the security of data elements,and build a reasonable digital governance system.
