Research On The Impact Of Infrastructure Construction In The Western Region On Total Factor Production Rate

The report of the Nineteenth National Congress of the Communist Party of China clearly put forward the implementation of a new round of regional coordinated development strategy,and regarded the establishment and improvement of balanced development of infrastructure networks as an important goal of regional development strategies.China’s economic development has changed from simple quantitative growth to the improvement of development quality,forming a reform situation of comprehensive improvement of "quality,efficiency and power",and improving the level of total factor productivity has become the key to achieving high-quality economic and social development in China.In the face of the new pattern and new measures of the third decade of the largescale development of the western region,the construction of open infrastructure channels and the expansion of inter-regional interaction and cooperation have become the focus of development.The regional gap in the development of infrastructure construction in the western region is still relatively prominent,and the important task of coordinated regional development is to rationally lay out the infrastructure network,build regional transportation internal and external connection channels and major urban hubs.How the western region can make use of its vast geographical location,abundant natural resources,and favorable support from state policies to increase investment in infrastructure construction and make effective use of infrastructure resources is of great significance to realizing regional economic integration,narrowing the gap in economic development,and improving total factor productivity.First of all,taking infrastructure construction as the research object,the relevant literature is sorted out and summarized,based on the theory of economic growth and the theory of new economic geography.The impact mechanism of transportation,information and energy on total factor productivity is analyzed.Secondly,the current situation of infrastructure construction in the western region is analyzed from four major sectors and two levels,and the DEA-Malmquist index method is used to measure the changes in the total factor productivity of the western region,the southwest and northwest regions,and the total factor productivity is decomposed into two aspects: technological progress and efficiency improvement.Panel data of 75 prefecture-level cities in the western region from 2001 to 2019 were selected,and a spatial Dubin model was established to empirically analyze the spatial spillover effect of infrastructure construction affecting total factor productivity.Finally,we propose countermeasures to the growth of total factor productivity affected by infrastructure.Conclusions:(1)The infrastructure stock in the western region is at a low level in the country,and the difference between the southwest and northwest regions is quite large.(2)The change in total factor productivity in the western region stems from the contribution of factors of technological progress,while the southwest region is mainly based on the contribution of efficiency improvement,and the northwest region is more balanced.(3)The transportation infrastructure in the western region has a positive role in promoting the growth of total factor productivity,but there is a negative inhibitory effect on neighboring areas;energy infrastructure has a significant negative spatial effect on improving local total factor productivity and a positive spillover effect on neighboring areas.The spatial spillover effect of the information infrastructure did not show significant,and the long-term effect was weaker than the short-term effect after the spatial spillover effect was decomposed.
