淮海经济区中心城市辐射效应综合测度与提升路径研究

Comprehensive Measurement and Promotion Path of Radiation Effect in Central City of Huaihai Economic Zone

本文以淮海经济区10个地级市作为基本研究单元,选取济南、合肥、南京和郑州四大省会城市作为辐射源城市进行对比分析。通过构建城市辐射力综合评价指标体系,采用熵值法计算城市辐射能力。对传统引力模型内的城市质量、距离等指标进行改进,探析城市辐射能力水平、格局。

In this paper,10 prefecture-level cities in Huaihai Economic Zone were taken as the basic research units,and four provincial capitals,including Jinan,Hefei,Nanjing and Zhengzhou,were selected as radiation source cities for comparative analysis.By constructing the comprehensive evaluation index system of urban radiation capacity,entropy method was used to calculate the effect of urban radiation capacity.on the urban quality in the traditional gravity model.The indexes of city quality and distance in the traditional gravity model were improved,so as to analyze the level and pattern of city radiation capacity.
