Research On The Influence Of Economic Development On Regional Integrated Transportation Structure

The transportation industry is the foundation and leading industry of the national economy,and it is also a subsystem of the social and national economic system.The social and economic production put forward the transportation demand,while the transportation supply of the transportation industry guarantees the normal running.When the transportation demand supply is compatible,the integrated transportation will positively promote the social and economic development.The social economic operation under different development levels has a large difference in transportation demand,which requires the transportation industry to provide a suitable transportation supply,thus promoting the integrated transportation structure to adapt to the new social and economic development needs.Now China's economy entering a new normal development status,it is necessary to clarify the impact of economic development on the regional integrated transportation structure,analyze the transportation demand generated by economic production,and adjust the development of the integrated transportation system according to the transportation demand,make it achieves the greatest social and economic benefits.First of all,after combing and learning related theories,this paper clarifies the connotation of the integrated transportation structure,sorts out the development model of the integrated transportation system,and clarifies its coupling relationship with the social national economic system.Then,this paper selects the related factors affecting the development of integrated transportation in the region,constructs the transportation-economic Deng's gray correlation model based on the grey system theory;then proposes a method to analyze the relationship between economic growth and transportation growth based on Granger causality test.Based on the econometric model,this paper constructs a regional integrated transportation demand model and proposes a research method to quantitatively analyze the impact of economic development on regional integrated transportation structure.Finally,this paper selects Chongqing as a case,uses the above models and combines the statistical data of various indicators from 1997 to 2017 to analyze the related factors of Chongqing's integrated transportation;analyze the interaction between Chongqing's economic growth and transportation growth;then establishes a integrated transportation demand model based on VAR model in Chongqing,analyze the impact of economic development on the integrated transportation structure of Chongqing,predict the integrated transportation demand structure of Chongqing in 2020,and put forward some suggestions for the future integrated transportation development of Chongqing.
