中国城市规模分布及影响因素实证研究

China's Urban Size Distribution and Effect Factors of Empirical Study

文章应用城市位序—规模法则与分形理论,测算了1999—2008年间分别以城市人口、建成区面积和经济规模表征的中国城市规模分布分维值,对分维值进行了纵向对比分析,并实证分析了影响城市规模的主要因素。研究结果显示:中国城市规模分布具有显著的分形特征,符合城市位序—规模法则;1999—2008年间三种表征的中国城市规模分布分维值均呈现下降趋势;中国城市规模具有明显区域性差异,资本投入、科技水平、产业结构和外资是推动城市规模扩大的重要因素。最后,文章据此提出了发展和完善中国城市规模体系的对策建议。

The application of urban rank-size rule and fractal theory,the calculation of the 1999-2008 years,respectively,the urban population,built up area and the economies of scale characterize the size distribution of Chinese cities fractal dimension,fractal dimension values of a longitudinal comparative analysis And empirical analysis of the main factors affecting the urban scale.The results showed that： the size distribution of Chinese cities has obvious fractal characteristics in accordance with urban rank-size rule;1999-2008 three years,China＇s city-size distribution characterized by the fractal dimension showed a downward trend;China has significant regional differences in city size,Capital investment,technological level,industrial structure and scale of foreign investment is to promote an important factor in the city.Finally,the paper thus proposes the development and improves the system of urban scale countermeasures.
