对中国不同区域大中小城市真实收入的比较

Real Income Comparison of Big,Medium and Small Cities in the Different Regions of China

城市规模与城市真实人均收入水平呈"倒U"关系,"倒U"曲线的顶点对应的才是最优城市规模和最大真实人均收入水平。本文通过对我国东中西部大中小城市经生活成本调整后的真实收入水平比较后发现,一方面,东部大型城市的真实收入水平已经低于部分东部中小城市和中西部核心城市;另一方面,仍存在许多内陆中小城市的真实收入水平低于东部大型城市,这将会成为吸引人口继续流入大城市的重要因素,未来大型城市仍将面临较大的人口压力。

It is recognized that the city size and its real average income show an inverted U-shaped relationship,and corresponding to the vertices of the curve are the optimal city size and maximum level of real average income. By compare the eastern,central and western cities' real income,adjusted for cost of living,this paper found the following results. On the one hand,the real incomes in eastern big cities have below that of part eastern middle and small cities and even central and western core cities. While on the other hand,many inland medium and small cities' real average income still have below the eastern big cities,which will have been becoming the important factor in attracting people to flow into big cities. It is predicted that large cities will still face enormous pressure from large population in the feature.
