Abstract:

With the development of economic integration,the economic links between cities had been increasing,it would inevitably lead to the logistics demand increased between cities.By drawing on the application of the gravity model in economy,the economic linkages were analyzed among cities in Jiangsu coastal areas.The results showed that the strength of economic ties became weak as the distance increasing;regarding the regional central cities as center,radial circle construction and three levels was present;competition to economic hinterland became more obvious among the regional central cities.Based on the network principle of transportation geography,the economical relation characteristics were further investigated from flow rate and direction of passenger,cargo and information.The results indicated that the cargo flow of LianyungangNantong played a major role;passenger flow of LianyungangNantong was more than the others;inconvenient information transmission and weak information flow was dominant.According to the spatial characteristics of economic contact and logistic flow,some suggestions for strengthening region economic cooperation were put forward
