摘　　要： 文章引入"生态位"概念,通过构造地区人口生态位指标体系,对我国地区人口生态位进行综合评价,并分析了地区人口生态位与地区人口流入、流出和净流入的关系。人口生态位综合评价结果表明,我国省际人口生态位差异大,北京、上海和天津等沿海发达省市人口生态位较内陆省市高很多,人口由生态位低的地区向生态位高的地区流动;分地区偏最小二乘回归模型则表明人口跨地区流动的影响因素存在差异,经济和知识技能子生态位仍是引起人口流动的最主要原因,但并不能很好解释所有地区,说明人口与经济、社会、资源和环境等人口生态之间是复杂动态系统关系,且影响人口流动的因素也因地区和时间而不同。 The article introduces the concept of ＂niche＂, and from the perspective of niche studies the deep-seated reasons of the population flow and the possible development trend, and constructs the index system of regional population niche,and evaluates China＇s inter-provincial niche, and then analyzes the relationship of the regional population niche and inflow,outflow and net inflow of the regional population. The results of empirical study show that China＇s population niche differences. The population niche of the coastal developed provinces and cities as Beijing, Shanghai and Tianjin are much higher than the inland provinces and cities. The population flow from areas of low niche to areas of high niche. The economy and environment are the main factors to attract the population inflow,while knowledge skills and traffic conditions are not the important limiting factors of the population outflow.
