Research On The Impact Of "New Infrastructure" On Total Factor Carbon Productivity

Under the "double carbon" goal,the proposal of new infrastructure provides a new path for economic,efficient,green and low-carbon development.In response to the call of the "Fourteenth Five Year Plan",to strengthen the construction of new infrastructure and accelerate the realization of the "double carbon" goal,research was carried out around the theme of the impact of new infrastructure on total factor carbon productivity.First of all,the relevant literature on new infrastructure and carbon total factor productivity is summarized and reviewed,and the issues to be studied are proposed.Secondly,it defines the concepts related to new infrastructure and total carbon factor productivity,and analyzes the impact of new infrastructure on total carbon factor productivity and possible mechanisms.Based on the provincial panel data of China from 2006 to 2020,the nonperiodic output super efficiency SBM model combined with the global GML(Globe Malmquist Lounberger)index is used to measure the growth rate of carbon total factor productivity,and it is decomposed into technical progress and technical efficiency indexes.According to the results obtained,the spatial-temporal evolution of total factor productivity of carbon is analyzed from multiple perspectives.Based on the theory,a panel double fixed model is constructed to empirically analyze the impact of new infrastructure on total factor carbon productivity.Further,from three aspects of information infrastructure,innovation infrastructure and integration infrastructure,analyze the impact intensity of different types of new infrastructure on total factor carbon productivity,and analyze the regional heterogeneity of the model.In the mechanism analysis,industrial upgrading,technological innovation and resource allocation are used as intermediary variables to explore the impact path of new infrastructure on total carbon factor productivity.Through robustness and endogenous tests,further verify the impact of new infrastructure on total factor carbon productivity.Based on the above research,feasible suggestions are put forward.The following conclusions are drawn:(1)The overall level of total carbon factor productivity across the country is rising,and the growth rate of technological progress is faster than that of total carbon factor productivity,which is the main source of carbon total factor productivity;There are differences in total carbon factor productivity between the eastern region and the central and western regions,and the differences are increasing.(2)The new infrastructure can promote the improvement of total carbon factor productivity,which can not only promote technological progress,but also improve technical efficiency,and double drive the improvement of total carbon factor productivity;The impact of information infrastructure,innovation infrastructure and integration infrastructure on total factor carbon productivity has shown a significant role in promoting.(3)The new infrastructure in the eastern region has a significant role in promoting total factor carbon productivity,while the new infrastructure in the central and western regions has no significant impact on carbon productivity.(4)New infrastructure can improve carbon total factor productivity through three paths: industrial structure upgrading,technological innovation,and resource allocation efficiency optimization;The promotion effect of industrial structure upgrading on carbon total factor productivity mainly depends on technological progress,while technological innovation and resource allocation efficiency are reflected in the improvement of technological efficiency in promoting carbon total factor productivity.
