| 摘 要： | 归纳了中心地模式和网络化模式两种空间组织模式的基本特征,即前者以向心型的垂直联系为表征,而后者以跨越腹地边界的多向联系为表征,并在此基础上研究了网络交互作用下长三角区域空间结构的演化趋势.首先以企业联系为分析视角,研究了不同强度、不同方向的网络"流量"变化趋势;其次,选择社会经济变量,通过主因子分析对地域类型进行划分,...

| Abstract: | This paper summarizes the basic characteristics of spatial organization of two models, Center Place Model and Network Model. The former is featured by centripetal vertical links, while the latter by multiple links across the border of hinterland. On this basis, the research focuses on the evolution of spatial structure in the Yangtze River Delta under network interaction. Firstly, with the analysis object of the connection among firms, this paper studies the evolution of the network connection of the region and makes a comparison of different flows, which include intensity and directions of network in the network connection within each region and among regions. Secondly, this paper applies the factor analysis technology to group the regional socio-economic types and analyzes the spatial structure evolution of the Yangtze River Delta. Thirdly, through the comparison between network interaction and changes of the areal type, the trend of polycentric networking and regionalization of the cities in the Yangtze River Delta is concluded as the Center Place Model still in dominance is weakening, while the Network Model is strengthening. Finally, the paper tries to explore the mechanism of the evolution from the increasing or decreasing returns of economic scale, which caused centralization or diffusion respectively. |
