| In the new era,China has paid more attention to environmental issues while pursuing economic development,and adhered to the new road of industrial development.We should not only pursue high-quality development of industrial economy,but also pursue green and sustainable development mode,and reduce new industrial pollution and ecological damage as far as possible.In recent years,China has vigorously developed the new generation of digital technology and actively promoted the reform of industrial digitalization,making the digitalization is gradually penetrating all walks of life and become the main driving force of economic development.Digital transformation can make full use of effective data connection across industry physical world and digital world,through huge amounts of data to build digital twin system,forming digital assets,through change innovation paradigm,reshape the production process,improve production efficiency to optimize the allocation of resources and industrial structure change,in promoting industrial structure upgrading,production mode innovation and energy conservation and emissions reduction has wide application potential.However,it is urgent to further study and analyze whether the digital transformation can effectively improve the industrial green total factor productivity in China,and what mechanism and path to promote the green total factor productivity of industrial industry.This paper first combs the literature and summarizes the academic literature on digital transformation and green total factor productivity.Secondly,the relevant concepts of digital transformation and green total factor productivity are defined,and on the theoretical basis of this paper,the influence mechanism of digital transformation on industrial green total factor productivity is studied.Thirdly,the evaluation index system of industrial green total factor productivity is constructed,and the DDF-GML index is used for calculation.Finally,empirical test and the following conclusions are drawn: First,the overall mean and ranking of industrial green total factor productivity at the provincial level show the characteristics of the eastern coastal areas far ahead of the central and western regions.Due to geographical location,initial endowment and other reasons,the average annual growth trend of industrial green total factor productivity in different regions is also uneven,and the development is uneven.Second,there is a linear impact between regional digital transformation and industrial green total factor productivity.The improvement of the degree and speed of regional digital transformation can effectively promote the improvement of industrial green total factor productivity.Among them,the innovation of regional production mode is an important transmission mechanism,while the upgrading of industrial structure has a covering effect in the transmission.At the same time,there is sub-dimensional heterogeneity,period heterogeneity on industrial green total factor productivity and regional heterogeneity.Third,the regional digital transformation has a nonlinear impact on the industrial green total factor productivity in different scenarios.Financial development has shown a regulatory effect in the process of digital transformation affecting industrial green total factor productivity.Under different agglomeration of producer services,different human capital levels and different marketization levels,there is a threshold effect of digital transformation on industrial green total factor productivity.Fourth,there is a spatial spillover effect of the degree of regional digital transformation on the improvement of industrial green total factor productivity. |
