基于城市中心性的广东省域内经济关联强度分析

为提高广东省各城市均衡发展状况,运用城市中心性及经济关联强度对广东省21个地级市进行综合测度,构建城市中心性指标体系,计算广东省各城市综合得分,确定中心性城市,并引入引力模型,以广州市为辐射源,测算省域内各城市与其之间的经济关联强度。结果表明:中心性城市同其他各城市间的经济关联强度差异明显,受城市的经济发展水平及相对位置关系影响较大,并基于此提出增强城市经济关联强度的对策建议。

Analysis of Economic Correlation Strength in Guangdong Province Based on Urban Centrality

To improve the balanced development of cities in Guangdong Province. Comprehensive measurement of 21 prefecture-level cities in Guangdong Province using urban centrality and economic intensity. Construct a city-wide index system, calculate the comprehensive scores of cities in Guangdong Province, and determine the central cities. Gravity model is introduced and Guangzhou City is used as the radiation source to measure the economic correlation intensity between cities in the province. The results show that the intensity of economic correlation between central cities and other cities is obviously different, which is greatly influenced by the level of economic development and relative position of cities. Based on this, the countermeasures and suggestions for enhancing the intensity of urban economic association are proposed.
