文章基于中国第五、六次人口普查与2005年1%人口普查数据资料,采用流数据分析方法,运用GIS空间分析技术,选用省际人口迁移的最大联系线、最大迁出流、最大迁入流、期望线、迁移效率、粗迁移率等方法系统地研究了我国1995—2010年间省际迁移的时空动态特点及其区际联系。结果表明:全国省际人口迁移的流动性不断增强,东部地区更明显;省际最大人口迁出与迁入流反映了中国省际区域间空间相互作用整体框架,全国大致可以分为3个人口吸引片区和5个辐射片区;省际最大净迁移流主要分布在东南沿海地区,中、西部地区分布较少,其空间分布与各省的MEI(i)指数密切相关。
Based on two rounds of the population censuses in 2000 and 2010, and 1 % sample population survey in 1995 respectively, the paper analyzed the spatial and temporal changes in China's interprovincial migration flows between 1995 and 2010 by the methods of the largest interprovincial migration flows, the largest interprovincial immigration flows, the largest interprovincial emigration flows, the desire line of migration, the crude migration probability and the migration effectiveness index. The results of the analysis revealed the following characteristics of China's interprovincial migration flows. Firstly, China has experienced a dramatic increase in interprovincial migration in 1995—2010 and the main part of it is provincial migration. The interprovincial migration population in China was increasing a lot in 1995—2010, especially in the eastern part of it. The coastal regions such as South China, East China have increasingly benefited from inflows of migration, and the gap of net migration balances between the coastal regions and the interior has been widening. Net migration has become an increasingly effective factor for population redistribution. Secondly, the largest interprovincial immigration and emigration flows revealed the spatial framework of regional interaction in China, which can be divided into three attraction and radiation zones respectively. The total number of migration, immigration and emigration, the relative proportion of interprovincial and provincial migration have been positively correlated to the regional economic development level. Thirdly, the distribution of the largest interprovincial immigration flows is related to the migration effectiveness index, which mainly distributed in the southeast coastal area and rarely in the western region.
