Abstract: Since the reform and opening up, the scale of China's floating population has been increasing, and the proportion of inter-provincial migrants has been also increasing. Although there are many studies on Inter-provincial Migration of floating population, few focus on inter-provincial migration distance. Based on the 2000 and 2010 census data, this paper examines the migration distance per capita and differentials by province. The results show that the migration distance per capita in China kept increasing from 980.51 km in 2000 to 994.82 km in 2010. The provinces with higher migration distances are mainly located in the west, while the provinces with lower migration distances are mainly located in the east. There are gender differences in migration distances per capita, and females are more inclined to close migration. In 2010, the average migration distance of males was 1000.75 km, while that of females was 987.01 km. The gender differences in migration distances are shrinking. At the same time, the paper also discusses the influencing factors of Inter-provincial Migration of migrants from three aspects: economic factors, age structure and migration scale.

摘要： 改革开放以来，中国流动人口规模不断增大，跨省流动人口比重也在不断提升，虽然关于流动人口省际迁移的研究较多，但是针对省际迁移距离的研究则不多见。文章利用2000和2010年人口普查数据考察人均迁移距离及其省际差异，研究发现：2000~2010年我国流动人口省际人均迁移距离有所增加，2000年人均迁移距离为980.51千米，2010年为994.82千米；人均迁移距离变动存在区域差异性，迁移距离增加的省份主要分布在西部，而迁移距离降低的省份主要分布在东部；人均迁移距离存在性别差异性，女性更加倾向于近距离迁移，2010年男性的人均迁移距离为1000.75千米，女性则为987.01千米，迁移距离的性别差异在不断缩小。同时，文章还从经济因素、年龄结构和迁移规模3个方面探讨了流动人口省际迁移距离的影响因素。
