Abstract:

This article focuses on the differences of regional development and the changes of spatial structure resulted in the introduction of some new factors. Based on the data of road efficient, ordinary train, CRH and information network of 13 cities in Jiangsu Province, we analyses characteristics of provincial spatial structure and judge the development trend from the viewpoint of space of flows. The results are as follows: 1) The road and ordinary train network shows a relative disordered spatial structure and its impact scope is also limited. The CRH network highlights the important position of the developed areas and expands the effective range of the city along the Beijing Shanghai High-speed Rail greatly. The information network reflects a more complete, orderly and coordinated spatial structure, which also represent the future of the comprehensive linkage network in Jiangsu Province. 2) Under the impact of CRH and information network, the factors which dominates the regional spatial structure is not the space of places but the space of flows. So some new features and trends which are different from the traditional ones are found, such as connecting with non-adjacent cities and the tendency of “hierarchy+network”. 3) Different from the traditional judgments of spatial structure in Jiangsu Province, this paper which is based on the comprehensive linkage network of traffic and information flow presents the obvious pattern of "core-periphery". The regional connection density declines from HuNing line to the coastal line and the calculation of SSI also supports this assertion. 4) The new element flows generate positive and negative influence to the efficiency and justice of changes of the spatial pattern in Jiangsu province. The former reflects in the improvement of regional accessibility and promotes the development of regional economy and the latter reflects in the huge "siphon effect” in the core cities. But with the improvement of regional comprehensive connecting network and the strengthening of radiation in Shanghai-Nanjing axis, the cities in Middle-Jiangsu and North-Jiangsu will function more as the central cities and transfer stations on the other hand, which can also help the Yangtze River Delta to step into the era of network and polycentricity.
