利用2000年和2005年人口普查数据，分析了1995年以来中国省际人口迁移的流场和区域差异，发现迁移规模扩大，方向从中部省份向东部三大三角洲地区集中，且长三角的移民规模与广东相当。
Inter-provincial migration led by rapid socio-economic development and more seriously regional unevendevelopment has become more larger.Using the data of the 1 percent census in 2005 and 10 percent census in 2000,this paper analyzes the flow field and its regional differentiation of inter-provincial migration in China since 1995.It is found that migration has reached a new scale.It remains the same,even stronger trend with migration direction from mid-belt including Sichuan,Hunan,Jiangxi,Henan and Anhui to east developed belt especially including the Peal River Delta,Yangtze River Delta and Jingjintang Delta.Rapid economic development in Yangtze River Delta has lead to large scale of immigration with gross amount similar to that in Guangdong.But in Guangdong,with large increasing amount of immigration,the amount of emigration to neighbor provinces is also increasing significantly.
