摘　　要：如何缩小地区间收入差距备受学界和政策制定者的关注。尽管多中心被规划者视为缩小地区收入差距的灵丹妙药,然而支持这一观点的实证研究较少。基于LandScan人口数据和夜间灯光数据,以全球132个国家为研究对象,采用面板固定效应模型和两阶段最小二乘法探讨城市规模分布对地区收入差距的影响。结果显示,城市规模分布多中心并不能缩小地区收入差距,反而会导致区域差距扩大。单中心缩小区域收入差距意味着单中心促进小城市人均收入增加要大于大城市,这是非均衡发展过程的空间表达,显示出经济会在集聚中走向平衡。未来应适度放松对大城市人口流动的限制,引导城市规模合理分布。How to reduce regional income disparities has long been the focus of geographers,economists and policymakers.Although polycentricity is regarded by planners as a panacea for narrowing regional income disparities,there are few empirical studies supporting this view so far.Based on Landscan population data and night lighting data for 132 countries around the world,using panel fixed-effects model and two-stage least squares method,this paper explores the effect of city size distribution on regional income disparities in a cross-country perspective.The study finds that polycentricity does not reduce regional income disparities,but rather leads to an increase in regional disparities.Monocentre reduces regional disparities mainly by promoting faster growth of per capita income in smaller cities than in larger ones.This is the spatial expression of non-balanced development,which shows that the economy will move towards equilibrium through agglomeration.In the future,restrictions on the movement of people in large cities should be relaxed to a reasonable extent to guide the rational distribution of urban size.
