| In20Century, China’s railway has entered a period of rapid development, high speed line was born. After recent years of development, our country especially in the southeast coastal area has built a number of high-speed railway passenger dedicated line (PDL)"high-speed rail network has begun to take shape four horizontal". Chengdu to Chongqing PDL as "horizontal" and "Hu-Han-rong channel" an important part, at the same time as an important link between Chengdu and Chongqing two West Center City, is very valuable for its direct impact area in Cheng-Nei-Yu development belt with the economic impact study. The development of PDL and into Cheng-Nei-Yu development belt is mutual benefits, complement each other. PDL can strengthen the contact city and urban and rural areas, promote the role of radiation area center city strong, to promote regional economic development, regional economic development in turn and can drive passenger dedicated line. So, whether from the angle of theory and empirical point of view, are of great significance to study the relationship between the line and the regional economy between the passengers.Papers focus on analyzing the construction of the Chengdu-Chongqing into a passenger line with the Chongqing development impact. Describes the passenger line and regional level, channel level, the basic theory of accessibility, focuses on the construction of the Chengdu-Chongqing Passenger Line motivation, Chengdu-Chongqing PDL development with respect to the economic, social and environmental impact of transportation in three areas. The use of qualitative and quantitative "pre-and post analysis" gravity model empirical analysis and other methods that can directly stimulate passenger line Chengyu regional GDP growth, increase local tax revenues, and promote related industries along the agglomeration and diffusion transfer, promote development along the urban agglomeration stimulate consumption increase employment conducive to environmental protection and traffic safety, improve the structure of a transport channel with the Chongqing development, improve transport efficiency and capacity, accessibility for the region has significantly improved. Finally, the use of input-output method, Sichuan Province and Chongqing Municipality to use two2007input-output table estimates for the construction of the Chengdu-Chongqing PDL with the economic development of Chongqing into the impact of industrial structure and proposed future development characteristics and trends in Cheng-Nei-Yu development belt. |
