长三角县域交通优势度与经济发展关系分析

Relationship Between Transportation Superiority Degree and Economic Development of County Territory in the Yangtze River Delta

基于耦合协调度模型,结合AHP法和模糊隶属度函数,对县域交通优势度与经济发展的协调关系进行了研究.以长三角16个核心城市51个县(市)为研究对象,计算各县(市)的交通优势度评价值、经济发展评价值及两者的耦合协调度,得出31个县(市)处于较高协调等级以上、2个县(市)处于低度协调等级的结论.最后针对不同类型协调等级的县(市)给出了相应建议.

Based on coupling coordination degree model,combining with AHP method and the fuzzy membership functions,the coordination relationship between county transportation superiority degree and county economic development was studied.Taking the 51 counties（cities）of 16 core cities in the Yangtze River Delta as the research objects,the evaluation values of transportation superiority degree and economic development were calculated separately,and the coupling coordination degree was also analyzed.It is concluded that 31 counties（cities）are in the high coordination level and above while 2 counties（cities）are in the low coordination level.Finally,the corresponding suggestions based on different types of coordination level of the county（city）are presented.
