财政独立性视角下中国各省城市人口齐普夫(Zipf)指数分布检验

Distribution of urban population Zipf index in China from the perspective of fiscal independence

大城市过大、小城市过小是目前我国城市人口分布的主要特征之一。针对这一现象,综合使用齐普夫(Zipf)指数、城市首位度和人口分布变异系数等指标,测度了各省人口空间分布状态,分析检验了政府财政干预等因素对人口分布离散度的影响方向与力度。分析发现:多数省份人口分布不合理;中央政府和省级政府的财政干预分别与省区城市人口分布的合理程度正相关和负相关。

Big cities too big, small cities too small, which is one of the main characteristics of the population distribution of urban system in today China. To this issue, we use Zipf index、City primacy degree and population distribution variation coefficient,measure the spatial distribution of population in China and the direction and intensity of government financial intervention on population distribution. In conclusion: The distribution of population is not reasonable in most provinces;the financial intervention of the central government is positively related to the distribution of urban population in provinces and autonomous regions;but the provincial government’s financial intervention is negatively related to the distribution of urban population.
