济南都市圈交通可达性与经济发展水平测度及空间格局研究

The Study about Measuring of the Relationship between Transportation Accessibility and the Level of Economic Growth and Spatial Structure at County Level

区域交通可达性与经济发展水平之间的关系历来是国内外学术研究的热点。以县域尺度为视角构建济南都市圈交通可达性测度指数和县域经济综合发展水平指数,以济南都市圈34个县市为例,构建11种交通可达性和经济发展水平组合类型,得出以下结论:①济南都市圈交通可达性区域差异较大,以低可达性和较高可达性为主,县域经济发展水平区域差异较小,以低经济发展水平和较低经济发展水平为主;②34个县市的交通经济组合类型分为11类,以交通可达性与经济发展水平协调型为主;③低可达性低经济发展水平类型县市数量最多,主要分布在德州、聊城、滨州等地市。研究济南都市圈县域尺度交通可达性与经济发展水平的测度及其空间格局能够为区域协调均衡发展提供较好的理论和实践指导。

The relationship between transportation infrastructure construction and economic growth has become a research hot spot at home and abroad, build 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 about Jinan metropolitan area 34 county-level cities, and build the 11 kinds of combination of the two types. We find those conclusion： （1） the traffic accessibility have large regional differences, the number of lowest reachability and higher teachability is most, the economic development have smaller regional differences, the number of the lowest economic level and lower economic level is most; （2） Combination types include 11 types which are maily identified as coordination type; （3） The types counties of most lowest traffic accessibility and lowest level economic development is most, primarily locate in Taian, Liaocheng, Binzhou City. 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.
