摘要:

随着经济一体化的发展,城市间经济联系日益加强,必然引起城市间物流需求联系的增加。借鉴引力模型在经济联系中的应用,分析了江苏沿海地区城市间经济联系强度。结果表明:城市间经济联系的强度随着空间距离的递增而递减;并以区域中心城市为中心,向外呈辐射状圈层构造,呈现3个层次结构;沿海中心城市对经济联系腹地间的竞争更加明显。立足运输地理学网络分析基本原理, 从客流、货流和信息流等流量,流向等空间属性进一步探讨城市间的经济联系特征,江苏沿海地区市际间货流量连云港南通占主要地位;客流量连云港南通一线最大;城市间信息传递不畅,信息流量较弱。针对城市间经济联系及物流要素流量的空间特征,提出了加强区域经济合作的策略与建议

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
