摘要
本文利用社会网络分析法对比探究我国南北方城市经济空间网络的结构特征,并分析不同城市板块的影响作用。研究发现:第一,南方城市之间的经济关联程度更强,经济影响传递效率更高,而北方城市间具有更严格的等级结构,经济空间网络的稳定性更好。第二,在南北方地区,经济发展水平较高的城市具有相对较高的点入度、较低的点出度,而经济发展水平较低的城市具有相对较低的点入度、较高的点出度,两大地区城市呈现出集聚发展的现象。第三,块模型分析中,南方城市多分布在“经纪人”板块及“净受益”板块,北方城市多分布在“双向溢出”板块及“净溢出”板块。相较于北方城市,南方城市具有更加明显的集聚发展趋势。
This paper uses social network analysis to compare and explore the structural characteristics of urban economic spatial networks in northern and southern China,and analyzes the impact of different urban plates.The research finds that:First,the economic correlation between southern cities is stronger,and the transmission efficiency of economic impact is higher,while the northern cities have a more strict hierarchical structure,and the stability of economic spatial network is better.Second,in the southern and northerm regions,cities with higher levels of economic development have relatively high point in and low point out,while cites with lower levels of economice development have relatively low point in and high point out.Cities in the two regions show the phenomenon of agglomeration development.Third,in the block model analysis,southern cities are mostly distributed in the“broker”plate and the“net benefit”plate,while northern cities are mostly distributed in the“two-way spillover”plate and the“net spillover”plate.Compared with the northerm cities,cities in the South have a more obvious trend of agglomeration development.
