长三角城市群金融资源空间流动研究

Research on the Spatial Flow of Financial Resources under the Background of Urban Financial Integration in the Yangtze River Delta

该文利用2003-2013年长三角城市群各县市金融资源数据,采用社会网络分析方法对金融资源空间流动的网络特征进行研究。研究发现:第一,城市群内的金融资金关联系数呈现出稳定的上升趋势,从2003年的277个上升到2013年的596个,整体网络密度由2003年的0.054上升到2013年的0.117。第二,地级市在长三角城市群中处于金融核心地位,在金融资金地域流动中发挥着组织、集散和传输的枢纽功能。县市类城市与其他城市之间的关联程度最低,在城市群中处于金融腹地地位。第三,根据金融资金的流动特征可以将各城市划分为四种类型:"主溢出板块"、"主受益板块"、"净受益板块"以及"孤立板块",其中"主溢出板块"的城市主要位于沪宁经济走廊上,且以地级市中心城市和县级市为主,而"孤立板块"为城市群东南部位置较为偏远的一些县市。因此决策者应该高度重视这些偏远地区的县市,应加强这些地区和其他地区之间的金融联系,使其也参与到城市群一体化的建设中来。

Using the financial resources data of the Yangtze River Delta from 2003 to 2013,this paper analyzes the network characteristics of the spatial flow of financial resources.The study finds that,firstly,the financial capital correlation among the city group is on the steady rise.The cities of prefecture level play a key role in the organization,distribution and transmission for regional flows of financial capital.Secondly,the cities of county level are at the position of financial hinterland with the lowest degree of correlation with other cities.Thirdly,the cities can be divided into four types,＂main overflow plate＂,＂main inflow plate＂,＂net inflow plate＂and ＂isolated plate＂according to the characteristics of the flow of financial capital.The cities of the ＂main overflow plate＂are mainly located along the line between Shanghai and Nanjing,while the＂isolated plate＂is located in the southeast of the city group.Therefore,it is suggested to attach importance to remote counties and cities and strengthen the financial links between these regions and other regions,in order to impel the urban integration.
