摘要： 在理论评述基础上, 构建了城市规模经济内涵的概念框架, 进一步应用计量分析方法, 探讨城市人口规模效益与经济规模效益。研究发现:现阶段我国的城市空间规模扩张整体呈现以人口增长为主要推动力;100～200万人口规模的城市每单位人口占用的空间规模相对较小, 从吸纳人口的角度应优先发展;200万以上人口规模的城市每单位人口占用的空间规模相对较大, 但每单位经济规模的空间占用较少, 从发展经济、增强区域竞争力的角度应适度发展;土地的集约利用可通过发展不同规模和类型的城市, 进而构建合理的城镇体系这一区域规划途径缓解或解决。最后, 本文从土地集约利用的角度, 针对目前的城市与区域规划实践提出了建议。

Abstract: Based on the review of the related literature, this paper builds a conceptual model to describe the meaning of urban economies of scale.On this basis, it uses the quantitative analysis to explore the relationship of urban scale economy, urban population size and urban spatial scale.The results are shown as follows.1)Nowadays, the main driving force of scale expansion of urban space is population growth.2)In the cities with a population of 10-20 million, the space occupied by per unit population growth is relatively large, which should be given priority to the development.3)In the cities with a population of over 20 million, the space occupied by per unit economic growth is relatively large, which should be developed on a moderate scale, and in regional development, one of the fundamental tasks is to build a rational urban system.Based on theoretical analysis, this study puts forward some proposals for the urban and regional planning.

Key words: population size, economies of scale, spatial scale, intensive land-use
