Abstract: Accelerate the digitization process of manufacturing industry, help enterprises with green transformation and development, and bring new opportunities for realizing the win-win goal of "golden mountain and silver mountain" and "green water and green mountain". This paper theoretically analyzes the theoretical mechanism of input digitization on enterprise green transformation production, and empirically tests the impact characteristics and mechanism of input digitization on enterprise pollution emission intensity and green growth efficiency combined with wiod input-output database, China industrial enterprise database and China industrial enterprise pollution emission and governance micro database. The results show that input digitization has a significant "emission reduction and efficiency enhancement" effect, and plays a role through the channels of technological innovation and production flexibility. The expansibility test shows that the "emission reduction and efficiency enhancement " effect of input digitization shows the characteristics of high energy consumption industry is greater than low energy consumption industry, capital intensive industry is greater than technology intensive and labor-intensive industry; Input digitization has stronger "emission reduction" effect on old industrial bases and resource-based cities, and stronger "efficiency enhancemen" effect on non resource-based cities and non old industrial bases.In addition, the high skilled labor factors of enterprises and the technology application and transformation ability of each province have a positive regulatory effect on the "emission reduction and efficiency enhancement" effect of input digitization. The research conclusions provide micro evidence and decision-making basis for accelerating the digital process and building an environment-friendly, optimized and efficient manufacturing development model.
