Study On Identification Of Comprehensive Transport Corridor And Impact On Economy In Urban Agglomeration

The comprehensive transport corridor is a transport route composed of sections between cities in the urban agglomeration area.Each transport route is composed of a variety of transport modes.The transport resources on the transport corridor are concentrated,and the traffic volume of the section is obviously higher than that of the surrounding sections.The business investment,human resources,tourism consumption and production materials are attracted to this area by characteristics of fast and large traffic volume of comprehensive transportation corridor.Therefore,comprehensive transport eorridor is very important for regional economic development.After the planning stage,the comprehensive transport corridor needs to be optimized and adjusted with the change of economic and social environment.It is necessary to analyze the transport eorridor from three aspects.First.the identification of comprehensive transport corridors;second,the impact of the layout of comprehensive transport corridors on regional economic development;third,the internal resource allocation of comprehensive transport corridors.Through these three aspects of work,we can grasp the change and development law of comprehensive transport corridor,improve the role of channel layout adjustment in promoting regional economic development,and provide operational decision-making basis for transport enterprises in the corridor.This paper comprehensively studies the identification and impact analysis of regional comprehensive transport corridors by using the relevant theories of transportation planning,transportation economy and statistical analysis.The main work of this paper is as follows:Based on the analysis of comprehensive transport network system,the formation mechanism of comprehensive transport corridor is analyzed,the application of equilibrium model and ant colony algorithm in quantitative identification of comprehensive transport eorridor is studied,the applieation of point-axis theory and dual-core structure in qualitative identification of comprehensive transport corridor is studied,and the identification method of comprehensive transport corridor based on quantitative model analysis and qualitative model selection is constructed.Based on the empirical analysis in Western Hunan,it is proved that the three stages of the evolution of comprehensive transport corridor and the feasibility of the quantitative and qualitative identification method of comprehensive transport corridor are feasible.Based on the spatial autocorrelation and spatial effect model,the impact of local comprehensive transport corridors on regional economic development is analyzed when connecting different regions with different levels of economic development.It is proved that when the economic development level of the comprehensive transport corridor connecting area is equal,the resource input of the local comprehensive transport corridor can promote the development of regional economy;when the regional economic development level of the comprehensive transport corridor connecting area is different,the resource input of the loeal comprehensive transport corridor can promote the development of regional economy with lower economic development level.The promotion effect of exhibition is small,even will inhibit the economic development of the region.The non-cooperative game equilibrium problem is introduced into the study of transport capacity input of enterprises in supply equilibrium state of each mode of transport,and the utility function of each mode of transport based on the demand side is constructed.The proportion of each mode of transport in the comprehensive transport corridor under the balance state of demand side and supply side is obtained.Through the empirical analysis of supply side and demand side,the question of supply-demand equilibrium is found.For this reason,the bi-level programming models of section layout and section transport structure optimization are constructed respectively,and the optimization suggestions of section selection for comprehensive transport corridor construction are put forward from the perspective of the government.From the perspective of transport enter:prises,this paper puts forward some optimization suggestions on service mode,transport means and information platform construction.
