在总结城市规模效益相关理论的基础上,提出了研究的基本理论假设。然后从城市经济效益、社会效益、环境效益三方面构建城市规模效益指标体系,运用修正后的灰色关联综合比较法对江苏省13个地级市2001-2005年的城市规模效益与城市规模进行相关分析,并讨论了5年内城市规模效益与城市规模时空演变关系,为城市达到最佳规模效益提供参考。
Basic theory hypothesis in research was put forward on the basis of summarizing relative theory of city scale efficiency. Then the index system of city scale efficiency was constructed from three aspects including economic benefit, social benefit and environmental benefit. The gray relevance total analysis was used to analyze the city scale efficiency and city scale of 13 cities in Jiangsu Province during 2001 to 2005. Relationships of spatio -temporal evolution between city scale efficiency and city scale were discussed, which offered references for cities to achieve the optimal scale benefit.
