摘　　要：以中国31个省级行政单位为研究对象,运用社会网络分析方法,探讨了1996-2020年中国省际人口流动的网络演变、作用机制与城镇化效应.结果表明:①省际人口流动网络的网络结构呈现持续加强的"小世界"特征;空间结构同时呈现东部集聚效应和中西部回流效应,反映了人口流动的路径依赖性和地理临近性;组织结构中各省份的网络地位呈现层级化分布特征,反映了人口流动的不均衡性和非对称性.②省际人口流动的驱动力源于流出地与流入地在经济发展、就业机会、社会保障、城市综合实力等方面的势能差,制约力源于流出地的地方依恋和激励效应以及流入地的制度性、经济性和技能性门槛,社会网络关系则强化了人口流动的路径依赖效应.③省级人口流动对全国和各省份城镇化水平的提升作用持续加强,其中,省内流动人口是推动城镇化水平提升的主要驱动力,跨省流入人口和跨省流出人口则共同构成了次要驱动力.This study takes China's 3l provincial-level administrative units as the research object,and uses social network analysis methods to explore the network evolution,mechanism and urbanization effect of China's inter-provincial population flow from 1996 to 2020.The results show that:The network structure of the inter-provincial population flow network shows the"small world"characteristics that continue to strengthen;the spatial structure shows both the eastern agglomeration effect and the central and western backflow effect,reflecting the path dependence and geographical proximity of population flow;the organizational structure The network status of each province in China shows hierarchical distribution characteristics,reflecting the uneven and asymmetric nature of population flow.The driving force of inter-provincial population flow comes from the potential energy diference between the outlow place and the inflow place in terms of economic development,employment opportunities,social security,urban comprehensive strength,etc.The restrictive force comes from the local attachment and incentive effects of the outflow place and the inflow place.institutional,economic and skill thresholds,and social network relationships strengthen the path-dependent effect of population flow.The role of provincial population flow in promoting the urbanization level of the whole country and provinces has been continuously strengthened.Among them,the floating population in the province is the main driving force to promote the urbanization level,and the inter-provincial inflow population and the inter-provincial outflow population together constitute the secondary driving force.
