Abstract:

The construction of SuzhouNantong Cross Yangtze Bridge and ShanghaiChongmingNantong Cross Yangtze Passage will lead to the evolution of the regional transport network pattern,which will deeply impact on the development of correlative region.As for as Nantong,the relative backward area in this region,the construction of the cross Yangtze passage is not only an opportunity but also a challenge to its development:(1) The accessibility of Nantong will be markedly improved after the construction,which makes Nantong convenient to connect the core areas in the Yangtze Delta,and the decrease of transport costs will accelerate the production factors agglomeration,but at the same time,the high quality factors are confronted with the potential drain risk.(2) The industrial scale will expand rapidly,but the lowerclass industry are dominant in this process,which increase the stress of industrial structure improvement,and the blind outspread and dispersed layout of construction land deteriorate the outoforder pattern of spatial exploitation.(3) With entering the compact circle of Shanghai Metropolitan Coordinating Area,Nantong is hopeful to establish the second tier cities in the north of the Yangtze Delta,but the competition stress will synchronously increases.For the sustainable development,some regionally efficient policies should be constituted on promoting city construction,agglomerating factors and the reasonably utilizing of spatial resources.
