摘要:

首先从人口、经济、用地3个维度综合考察武汉市增长与收缩的全貌,并采用县区及街道2个尺度的数据定量描述了武汉市增长与收缩的特征与空间格局,发现武汉市下辖青山区、硚口区、汉阳区和蔡甸区存在局部较严重的收缩现象,空间上形成集聚,形态上呈“穿孔式”。进一步以青山区为案例,着重从资本视角探讨发生局部收缩的内在机制,发现其存在老龄化、少子化趋势,但局部收缩的主因是资本从产业部门的“逃逸”。

Abstract:

Unlike large-scale shrinkage that prevails in an economic recession, “shrinkage under growth” is a new phenomenon in China’s urban development in recent years. Since 2000, Wuhan has shown a pattern of co-occurrence of growth and shrinkage in population and is regarded as a good sample for investigation. Thus, this paper first comprehensively examines the whole picture of growth and shrinkage in Wuhan from three dimensions: population, economy, and land use; then, it quantitatively describes its features and spatial patterns by using data from the county and street levels. The paper finds that 1) from 2000 to 2016, 116 of the 156 streets with complete data statistics showed growth in their population, among which 64 streets grew by more than 30%. Forty of the 156 streets showed a decline in population, and 29 have decreased by more than 10%. 2) The streets with rapid population growth were concentrated in the boundary areas between the inner city and the new city, where new urban residential land was supplied in large quantities. 3) The local shrinkage that was observed in the four areas-Qingshan District, Qiaokou District, Hanyang District, and Caidian District-was agglomerated in space and morphologically “perforated.” Using Qingshan District as a case study, it was found that the area presented a spatial pattern of [growth in the east, shrinkage in the central region, and parallelism in the west]. The paper then explored the internal mechanism of the local shrinkage from the perspective of “capital.” It is believed that there is a trend of aging and minority birth, but the main cause of local shrinkage is the “escape” of capital from the industrial sector. Subsequent research can focus on the following three aspects: the identification of “shrinkage under growth”; the in-depth discussion of the internal mechanism of “shrinkage under growth”; and judgments on whether shrinkage was a short-term phenomenon or a long-term trend.
