Shaanxi Highway Transportation Industry-Regional Economies-Ecological Environment Coordinated Developmental Research Based On Coupling Theory

The ecological environment is the foundation for the development of regional economies and highway transportation industry.As the artery of social and economic development,highway transportation industry connects all the economic bodies,improves the efficiency of circulation within the economy,but aggravates the ecological environment burden in the period of construction and operation.The rapidly developing economy provides support for improving the ecological environment and strengthening the construction of highway transportation industry.Similarly,a weak economy constrains the development of the ecological environment and the highway transportation industry.Studying coupling coordination of highway transportation industry-regional economies-ecological environment and its influencing factors will help to provide reference and reference for government departments to formulate relevant policies and measures,thus promoting the coordination and sustainable development of highway transportation industry-regional economies-ecological environment in Shaanxi province.This paper studies the coupling system of three subsystems of highway transportation industry,regional economies and ecological environment in Shaanxi Province,focusing on the coupling mechanism,coupling coordination and their influencing factors.This paper defines the concept of coupling theory,expounds the application of system theory,sustainable development theory and transport theory in this paper,and analyzes the coupling mechanism of these three subsystems.Empirical aspects: first,establish the evaluation index system of three subsystems,use the price reduction model and the max-min function function to preprocess data.Then,the entropy method and the weighted arithmetic mean method are used to calculate the order parameters of these three subsystems,and the coupling coordination degree model is used to solve the coupling degree,coordination degree and coupling coordination of these three subsystems.Besides,according to the relative size of the coordination grade and the order parameters of these three subsystems,the coordination grade and the coupling type are determined.Finally,the grey correlation degree analysis method is used to study the grey relation degree of the coupling coordination degree of these three subsystems and its influencing factors.The main conclusions of this paper are as follows:(1)From 2004 to 2016,the coupling coordination degree of highway transportation industry-regional economies-ecological environment in Shaanxi province increased overall.The current stage(from 2011 to 2016)fluctuates steadyly between intermediate coordination and good coordination;(2)In 2004-2016,The coupling type of these three subsystems is dominated by the ecological environment,leading to the highway transportation industry,and leading to the regional economies in Shaanxi province.(3)In the factors affecting the coupling coordination degree of these three subsystems in Shaanxi Province,its gray correlation degree is the highway freight volume and the turnover volume of highway freight,the ratio of the second industry to the first industry and the foreign investment.The number of funded enterprises,the amount of water resources per capita and pollution control have been completed.According to the research conclusion,this paper puts forward countermeasures for reference and reference for relevant government departments.
