Study On The Influence Of High Speed Railway Opened On Energy And Environmental Efficiency In China

Since 2008,high-speed rail has officially entered people’s production and life,opening the era of high-speed rail.With its unique advantages and huge road network scale,high-speed rail affects the regional industrial layout and resource allocation efficiency.Its direct effect and spillover effect significantly promote GDP growth and provide fresh blood for economic development.Although China’s high-speed railway started relatively late,it has realized several major speed increases and has relatively mature R & D technology.At present,China is committed to the construction of "eight vertical and eight horizontal" high-speed railway network,which will certainly bring more remarkable results.However,with the rapid development of economy,many problems have arisen,such as over exploitation of energy,low production efficiency and environmental pollution.Energy and environment efficiency,as a leading indicator to measure the quality of economic development,will directly affect the transformation of regional production mode.Compared with developed countries,China’s energy and environmental efficiency value is lower,which further reflects that enterprises lack certain technology,capital and other production factors.Therefore,how to improve energy and environmental efficiency has become a hot topic discussed by scholars.Through existing research,it can be found that industrial structure and technological innovation are two key factors affecting energy and environmental efficiency,and high-speed rail,as a pillar industry,has a wide impact on industrial structure and technological innovation.Therefore,it is of great theoretical and practical significance to study the impact of high-speed rail on energy and environmental efficiency.This paper builds a theoretical research framework based on the research on the literature and theory related to high-speed rail and energy and environmental efficiency,analyzes the impact mechanism of high-speed rail on energy and environmental efficiency from both direct and indirect aspects,uses DEA model to measure China’s energy and environmental efficiency in provinces and regions,and then uses panel regression model to regression analyze the impact of high-speed rail on energy and environmental efficiency,Then the regional heterogeneity and endogenous test are carried out,the industrial structure and technological innovation are set as threshold variables to analyze the effect.The following conclusions can be drawn from the research: first,according to the data of 263 cities in the country,it is found that the energy and environmental efficiency of each city has a certain volatility.According to the energy and environmental efficiency measurement data of 30 provinces in the country,it is at a relatively low level as a whole.According to the measurement of the three regions,it is found that the energy and environmental efficiency of each region is similar to the overall situation and has the characteristics of volatility;Second,through panel regression analysis,it is found that the opening of high-speed rail has directly promoted energy and environmental efficiency.When each unit of high-speed rail opening value is increased,it will bring 0.0071 unit of energy and environmental efficiency improvement.Through regional heterogeneity analysis,it is found that in the eastern region,the opening of high-speed rail has promoted energy and environmental efficiency;For the central and western regions,high-speed rail has reduced the energy efficiency of the central and western regions;Third,through the threshold effect analysis,it is found that the impact of the opening of high-speed rail on energy and environmental efficiency is constrained by the strength of regional industrial structure.With the change of its strength,the impact shows a significant negative and non-linear law of diminishing marginal efficiency.It is also constrained by the strength of regional technological innovation.With the change of its strength,the impact shows a significant negative and non-linear law of increasing marginal efficiency.
