摘要
基于2017年CMDS数据,运用社会网络分析、地理空间分析方法,解析中国京津冀、长三角、珠三角、成渝、长江中游及哈长城市群的流动人口居留意愿网络空间结构差异,划分其空间模式。研究发现,城市群居留网络整体上呈不同等级的“圈层”结构,距离衰减效应显著。居留网络结构特征迥异,沿海城市群流动人口来源腹地广,京津冀和长三角集聚效应明显,流动人口居留意愿更高;珠三角城市群居留强度低,结构松散。内陆城市群吸引范围有限,居留意愿低,成渝城市群居留联系弱,内外部流动相对均衡,长江中游城市群呈现弱集聚与轻均衡特征,哈长城市群内部结构紧凑,外部联系松散。不同区位、不同规模、不同发展阶段的城市群其居留意愿网络空间格局差异明显,流动人口居留选择具有明晰的地域指向。沿海城市群应加大区域低中心性城市发展,创造更多的就业机会,以吸引人口流入;内陆城市群应优化产业结构布局,平衡人口流出与流入,避免区域人口过度流失。
Identifying the network characteristics of settlement intentions of floating populations in urban agglomerations is of great significance in constructing a reasonable spatial distribution of the population and the urbanization of the floating population.Based on China Migrants Dynamic Survey(CMDS)data from 2017,this study used social network and geospatial analyses to examine the network spatial structure of floating population settlement intentions and identify their spatial model.Six major urban agglomerations were selected as case studies,including three coastal agglomerations—Yangtze River Delta(YRD),Pearl River Delta(PRD),and Beijing-Tianjin-Hebei region(BTH)—and three inlands agglomerations—Middle Yangtze River(MYR),Chengdu-Chongqing region(CC),and Harbin-Changchun region(HC).The results show that the residential network of urban agglomerations presents different levels of"circle layer"structure on the whole,and the intensity of residential contact exhibits a distance attenuation effect.The floating population in coastal urban agglomerations originates from a wide hinterland.The agglomeration effect of BTH and YRD is significant,and compared to the rest of the urban agglomerations its floating population exhibits a higher settlement intention.PRD has a low intensity of residential contact and a loose structure;the scope of attraction of inland urban agglomerations is limited,settlement intention is low,and the network is balanced.CC urban agglomeration exhibits weak residential connection,balanced internal and external flow of urban agglomeration,and a primary equilibrium state of its network.Furthermore,MYR urban agglomeration exhibits relatively low residential connection and weak agglomeration and slight equilibrium of its network structure.Meanwhile,HC exhibits a compact internal structure and scattered external structure.There are clear differences in the spatial patterns of settlement intention in urban agglomerations at different locations,scales,and development stages.The floating population's
