基于人口经济数据分析我国城市收缩现状

城市收缩作为城镇化进程中的普遍现象受到广泛关注。为了解我国城市收缩的现状,加深对我国城市收缩问题的理解,文章选取329个城市研究其人口变化表现,并从中筛选出64个收缩城市,进一步利用人口和经济两个特征对已识别的收缩城市的本质进行界定。其次分别从绝对收缩和相对收缩两个性质分析收缩城市形成的关键原因,发现绝对收缩城市的形成主要原因在于城市经济结构的瓦解,相对收缩城市的形成原因在于城市劳动力的大量外流。

Urban Shrinkage in China Based on the Data of Population and Economy

As a common phenomenon of urbanization, urban shrinkage has appealed for more and more attention. Urban shrinkage always happened in developed countries, but in recent years, some cities in China are shrinking. Urban shrinkage in China is different from developed countries. In order to find the features, this paper adopted retroduction method to filter 64 shrinking cities from all of 329 cities in China and defined the absolute shrinking city and relative shrinking city. Then, this paper used backtracking method to discuss the key factors caused the absolute and relative shrinking city. It is found that most shrinking cities in China are relative shrinkage, and labor movement pays many contributions to relative shrinking city;the formation of absolute shrinking city is caused by the collapse of the urban economic structure. The results are conducive to deeply understand the phenomenon of urban shrinkage in China and provide reference for policy recommendations.
