皖北地区人口省内异地城镇化特征及影响因素

The Characteristics and Influencing Factors of Trans-regional Urbanization of Northern Anhui Population in Other Places of the Province

基于皖北六个地级市(阜阳市、淮北市、宿州市、淮南市、蚌埠市、亳州市)2007—2017年统计年鉴上人口流动的数据,通过异地城镇化率公式以及迁移选择指数计算皖北各市的人口省内异地城镇化率,分析其时空变化特征以及影响因素.结果表明:(1)从时间维度来看,皖北人口省内异地城镇化率整体呈上升趋势,阶段性特征明显;城市间城镇化率虽然存在差异,但总体变化趋势较为一致;(2)从空间维度上看,合肥市是皖北地区人口省内异地城镇化的首选城市;皖南的芜湖市和马鞍山市次之;受空间临近性的影响,皖北内部城市间异地城镇化现象也较为普遍;(3)皖北的社会经济发展水平、各市的地理区位、省内社会经济发展的空间差异都是影响皖北地区人口异地城镇化的重要因素.

Based on the migration data of six cities(Fuyang,Huaibei,Suzhou,Huainan,Bengbu and Bozhou)in 2007-2017 statistical yearbook,this study examined the trans-regional urbanization rate of Northern Anhui population in other cities of the Province,and its spatial and temporal variation characteristics and influencing factors,using the selection index and urbanization rate formula.The results show that(1)From the perspective of time,the Northern Anhui people’s urbanization rate in other cities within the province is on the rise as a whole,with distinct staged characteristics;Although there are differences in urbanization rates between cities,the overall trend of change is relatively consistent.(2)From the perspective of spatial dimension,Hefei city is the first choice for the urbanization of Northern Anhui population.Wuhu city and Maanshan city came second;Due to the influence of spatial proximity,the urbanization phenomenon between different cities in northern Anhui is also common.(3)Social and economic development level of northern Anhui,geographical location of every city and spatial difference of social and economic development within the province are all important factors affecting Northern Anhui people’s trans-regional urbanization in other cities in the province.
