Computer Analysis on Network Space Characteristics of Economic Connection in the Yangtze River Delta Urban Agglomeration

Abstract

Networking development of urban agglomeration is one of essential characteristics of the integrative growth in the Yangtze River Delta region. In this paper, social network analysis (SNA) and kernel density estimation are combined through computer gravity model and structural model of urban agglomeration's economic networks is constructed. After an empirical study on 25 cities in the Yangtze River Delta, network density, kernel density distribution and cohesive subgroups of economic network in Yangtze River Delta urban agglomeration are analyzed by software UCINET and ArcGIS, to innovatively research the structure and networking development patterns of urban agglomeration. It is indicated by the results that a relatively mature net association has formed among cities in the Yangtze River Delta, while the centrality between cities in the network is imbalanced, so that relevant suggestions on network optimization of economic relation among Yangtze River Delta urban agglomeration are proposed. Research Background and Definition of Problems The Yangtze River Delta urban agglomeration is the largest urban agglomeration in China, as it is composed of city strip along the river and cities around Hangzhou Bay. With economic globalization and advancing urbanization, metropolitan areas and urban agglomeration network are formed. Regional economy's high-speed development enables the economic relation in urban system to be more active and develop in the unprecedented way, structure, speed and scale, gradually presenting the feature of networking. In this paper, social network analytical method of human geography and computer kernel density method are adopted to analyze network space structure of economic relation in the Yangtze River Delta urban agglomeration; based on related data of 2014, the strength of economic relation among 25 cities in the Yangtze River Delta is measured; network density and kernel density among cities are analyzed, so as to propose feasible suggestions on the development and optimization of the Yangtze River Delta urban agglomeration.
