Research on City Network of Northeast China Based on Space of Flows

Chen Chen;Xiu Chunliang;School of Geographical Science of Northeast Normal University;  
City system and its spatial organization are concerned greatly by geographers and city planners. As the important nodes of global economic network,there exists cooperative and dynamic network complementary relationship among cities. This article will take fund flow as an example to analysis city network spatial distribution characteristics of northeast China from the perspective of fund flow. Firstly,the spatial distribution characteristics of connection strength between cities will be analyzed. Secondly,starting from the angle of network nodes,this research will discuss the distribution of city importance degree or the city grade system in northeast China. Main conclusions are as follows: 1) From the first grade connection strength to the fifth connection strength,the change process of city network spatial distribution is along the Ha-Da mega-corridor→extending toward northeast→spreading to west→cover the small scale cities of northeast China→integral fund flow network migrating to north. Connection strength of fund flow between cities has highly polarization effect. The general connection strength of fund flow between cities in northeast China is weak. 2) The spatial distribution characteristics of the node of city network are that the higher relative network connection rate of Cities demonstrate"Ding-shaped"space structure. City grade system shows reverse pyramid distribution mode except the the first grade cities which are at the top of the pyramid.3) As the connection strength goes down,the scale of the cities convered by fund flow network become increasingly smaller. 4) The first three levels of relative network connection rate of cities show highly linear correlationship with the occurrence times of every city. And the relative network connection rate and the occurrence times of all cities has strong correlationship with their social and economic development level such as GDP and population size.
