Zipf定律在划定经济区域内的实证研究——以长江三角洲经济区为例

Empirical research of Zipf's law in the delimited economic area—A case study of the Yangtze River Delta

国外关于Zipf定律的实证研究的区域空间多采用国家层次,而国内关于Zipf定律的实证研究则涉及国家、跨省的经济区及行政省的不同层次,于是这就有可能存在经济区域空间划定是否合理的问题。现以长江三角洲地区为例,通过修正的引力模型计算城市之间的经济联系强度及潜能,以此进行长江三角洲经济区域的空间划定,并在划定的经济区域内进行Zipf定律的实证研究,以验证经济区域空间划定是否合理。研究结果显示了经济区域空间划定的合理性。

The foreign positive researches of Zipf＇s law are often related to country-level,but domestic ones are involved different levels of country,economic area surpassing several provinces and provinces.This brought the doubt if the delimitation of economic area was feasible.Taking the Yangtze River Delta for an example,the author computed the economic relation intensity and the potential to delimit the economic area of the Yangtze River Delta through the modified gravity model,and studied the Zipf＇s law in the determined economic area to test the reasonableness of the delimitation.The result revealed the reasonableness of the delimitation.
