Abstract:

The relationship between transportation infrastructure construction and economic growth has become a research hotspot at home and abroad, but there are few studies about the spatial structure of the relationship between comprehensive transportation accessibility and the level of economic growth at county level. Comprehensive transportation system is firstly mentioned in the 1950s, it refers to the comprehensive, dynamic, and complex system which is composed of five transportation modes including railway, highway, waterway, airway and pipeline. At present, foreign transportation industry is well known as the "fourth industry". Under the background of global economic integration, the transportation from the original production conditions evolving into national economic growth point and driving force, and expansion of space force contribution to regional economic development is rapidly increasing. In recent years, China has invested large amounts of funds in transportation infrastructure construction, the rapid development of highway, railway, civil aviation and other transport modes, and high-speed rail and other new traffic tools deeply influenced regional economic spatial pattern, such systemic problems need to have further research. There is need for keeping up with the changes, in order to maintain coordination between transportation and regional economy, but it is rare about three-dimensional, multi-dimensional, and high co-integration research at home and abroad. We need the corresponding research results to guide and support under the rapid development of economy and transportation industry. Based on existing achievements and 91 counties in Shandong Province, based traffic statistics in 2009 and the 2011 economic statistics in Shandong Province, the authors build a model of comprehensive transportation accessibility indexes which include center city location index, county road links degree and opening accessibility, analyze the characteristics of spatial structure of the relationship between comprehensive transportation accessibility and the level of economic growth, and build 16 combination types. Those conclusions are achieved: 1) The regional differences is huge about comprehensive transportation accessibility and the level of economic growth, coefficients of variation are 0.690 and 0.349; 2) Combination types include 12 types which are maily identified as coordination type, advanced type; 3) Coastal economic zone, Jinan metropolitan area, areas along the Jiaozhou-Jinan railway has a good advantage in comprehensive transportation accessibility and the level of economic growth which is at a high level of coordination, but there is existing opposite situation in the western Shandong. The study about to the relationship between comprehensive transportation accessibility and the level of economic growth will help to realize high level of coordination between transportation and regional economic development.
