【摘要】：县市是中国新型城镇化发展过程中调控流动人口的重要单元。本文系统梳理了1982年、1990年、2000年、2010年四期人口普查的流动人口统计口径,根据地理流数据的空间尺度转换原则,核算四期人口普查县市尺度的流入人口和流出人口,构建对应的流动人口空间数据库。并提出新的修正复合指标法,划分出6种流动人口地域类型,包括大规模净流入活跃型、小规模净流入活跃型、大规模净流出活跃型、小规模净流出活跃型、平衡活跃型、非活跃型,据此分析中国流动人口地域类型的演化格局。主要结论为:(1)中国流动人口地域类型经历了从不活跃到活跃、从相对均势到高度极化的演化过程,大部分地区逐步转化为净流出活跃型,流动人口向少数净流入活跃型县市集聚,51个大规模净流入活跃型县市集聚了全国55.85%的流入人口。(2)中国流动人口地域类型在空间格局同样呈现高度极化的演化过程,形成长三角地区、珠三角地区2个流入人口高度集聚区,京、津及其他省会或首府等大城市则呈现单核式吸纳流入人口,净流出活跃型在"胡焕庸线"东南侧的"秦岭—淮河"以南地区呈现大面积扩张,成为中国最大的流出人口源区。(3)社会经济因素逐步成为影响流动人口集疏的主导因素,行政等级因素的作用也愈发突出。
[Abstract]:Counties and cities are important units to regulate and control the floating population in the process of new-type urbanization in China. This paper systematically combs the floating population statistics caliber of the four population censuses in 1982, 1990, 2000 and 2010, and calculates the inflow and outflow of population from county and city scale according to the principle of spatial scale conversion of the data of the base area flow, and accounts for the inflow and outflow of population in the county and city scales of the fourth census. The corresponding spatial database of floating population is constructed. A new modified composite index method is proposed to divide six regional types of floating population, including large-scale net inflow active type, small-scale net inflow active type, large-scale net outflow active type, small-scale net outflow active type and balanced active type. According to the non-active type, the evolution pattern of the regional types of floating population in China is analyzed. The main conclusions are as follows: (1) the regional types of floating population in China experienced a process of evolution from non-active to active, from relative equilibrium to high polarization, and most areas gradually transformed into net outflow active type. The floating population converged into a small net inflow of active counties and cities. Fifty-one large-scale net inflow counties and cities gathered 55.85 percent of the country's inflow population. (2) the regional types of floating population in China also showed a highly polarized evolution process in the spatial pattern, forming the Yangtze River Delta region. The two highly populated areas in the Pearl River Delta region, while large cities such as Beijing, Tianjin and other provincial capitals or capitals, have single-core absorptive inflows. The active type of net outflow expanded in a large area south of the Qinling-Huaihe River, southeast of the Hu Huanyong Line, and became the largest source of outflow population in China. (3) socio-economic factors gradually became the leading factors affecting the concentration and distribution of floating population. The role of administrative hierarchy is becoming more and more prominent.
