改革开放以来西部地区人口分布与城市化的新动向

借助于人口集中指数、K信息量指数和城市化度等指标 ,对西部地区 1982— 2 0 0 0年间的人口分布和收入分布变化与城市化进程进行了定量分析 ,结果显示 :西部地区的城市化进程与人口的地域分布呈现反向变化 ,与人口的经济分布呈现出正相关关系 ;而且 ,通过分析西部地区 15年间的城市化度和城乡收入差距的数据发现 :西部地区的城市化进程更大程度上是受到相对城乡收入差距而非绝对城乡收入差距的影响 ,据此本文提出了通过保持适度城乡收入差距 (城乡收入比在 2 .75至 3.75之间 )来加快西部地区城市化进程的政策建议

The Population Distribution and the Urbanization of China West Areas

With the help of the index of population concentration, of K information volume and the degree of urbanization, this paper makes quantitative analyses of the population distribution and the urbanization of China west areas from 1982 to 2000. The result shows that the change of the west urbanization is contrary to the one of its zone distribution of population, but in accord with its economic distribution of population. Moreover, the fifteen-year data reflect that the west urbanization is more affected by the relative difference of income than the absolute one between urban and rural west. The paper thus proposes that in order to quicken the west urbanization the government hold optimal control over the income difference (at a range from 2.75 to 3.75) between the west urban and rural.
