Research On The Space Network Over The Process Of Integration In The Yangtze River Delta

Under the background of globalization, it is being obvious that regional integration. Urban agglomeration is an important form of region, and urban agglomerations in the world have been the cores who take part in the international competition. In China, urban agglomerations are the main forms what the urbanization with Chinese characteristics is looking for. And it is a principal strategy of region development that the development of urban agglomeration. Yangtze River Delta Urban Agglomeration is one of the most important urban agglomerations in China. It is mostly possible that it will be World-class City Groups, and there are many achievements about regional integration.The research of regional integration mostly depends on the measure of urban relation intensity, such as economy, traffic, and so on. There are some deficiencies in the space perspective about regional integration. Because of the limitation of administrative region economy and space limitation, regional spatial structure has obvious characteristics. Therefore, in order to improve the level of integration, it is necessary to analysis the spatial structure of Yangtze River Delta Urban Agglomeration and the relationship between cities.This paper includes the contents of three respects mainly. The first part of the paper introduces correlation theory and Research Summary. The second part of the paper is Empirical Study. This part firstly describes the integration development of Yangtze River Delta Urban Agglomeration, such as economic development, the Construction of Common Market, Cooperation Mechanism. To analysis the network space of Yangtze River Delta Urban Agglomeration and the network relationship between cities by using social network analysis. Concretely speaking, this paper describes three networks about traffic, economy and social, by using the data of passenger traffic flow, firm network and Baidu search index. The flight times of automobile and train between cities are used as the traffic flow between cities. Research shows that the network space of Yangtze River Delta Urban Agglomeration presents imbalanced spatial variation. Shanghai is the core of the traffic network. The level of network in Jiangsu province is higher than Zhejiang province. The connection between Jiangsu and Zhejiang province is low.The distribution of subsidiary companies what the parent companies are top of 500 enterprises in China stand for the contact of economy. Research shows that cities in Jiangsu province connect closely with Shanghai. The level of connection between cities in Jiangsu province is low. The cities in Zhejiang province connect closely with Shanghai and Hangzhou. The connection between cities in different provinces is low.The Baidu search index stands for the attention-degree between cities. Research shows that the level of social network is highest. But it is also obvious that the regional difference. Cities connect closely with the provincial capital city. The last part is conclusion and prospect. And according to the trend from these results, put forward related suggestions about Yangtze River Delta Urban Agglomeration.
