中文摘要：

港口后勤区域是港口功能的重要拓展空间，已成为影响港口物流运营效率的重要因素。运用ARCVIEW网络分析模块，从交通运输成本的角度，通过分析港口后勤区域候选点到直接腹地、间接腹地的运输成本，以及各候选点的综合运输成本进而对外高桥港口后勤区域区位进行研究。研究表明：外高桥保税物流园区至港区的运输成本系数为0．3814、0．2759、0．3195和0．21i8，整体处于较高水平；到直接腹地的运输成本系数分别为1．10793、1．13649、1．08524和1．10976，处于偏低水平；到间接腹地的运输成本系数分别为0．8745、0．935、0．8254和0．874，整体处于中等水平；到腹地的运输成本系数分别为0．9445、0．9954、0．9034和0．9447，整体处于中等偏弱地位。外高桥保税物流园区到港区和腹地的综合运输成本系数分别为0．663、0．6357、0．6114和0．5782，综合区位条件较好。今后，随着外高桥港区货运量的增加，保税物流园区应该向东南方向拓展。

英文摘要：

With the process of globalization, the competition among the ports, shipping lines and terminal operators to get more container traffic has been intense. To get more container traffic, some ports have been making a great effort to be a logistic hub to increase their competitive advantage. The port authorities have implemented various efforts, such as building logistic centers, expanding port backup areas, cooperation between port authorities in the same areas and advancing information technology systems. Meanwhile, among the factors yielding on a port competitiveness, performance or efficiency is considered as one of the most influential elements. The port backup areas advances their port competitiveness and increases their profit through improving port productivity and advancing value-added logistics. Under the circumstances, port backup area has attracted much attention in recent years as an important function area. From the per- spective of transportation costs, the article analyzes the transportation cost from the candidate points of port backup area to the direct hinterland and indirect hinterland, as well as the comprehensive transportation cost among the various candidate points,and makes further research on the location of Waigaoqiao port back-up area by use of the ARCVIEW network analysis module. The results show that the transportation cost from Waigaoqiao bonded logistics zone to the port is at a high level as a whole with the coefficient of 0. 381 4,0. 275 9,0. 319 5 and 0. 211 8 respectively;the transportation cost to direct hinterland is at a low level with the coefficient of 1. 107 93,1. 136 49,1. 085 24 and 1. 109 76 respectively; the transportation cost to indirect hinterland is at the central level as a whole with the coefficient of 0. 874 5,0. 935,0. 825 4 and 0. 874 respectively;the transportation cost to hinterland is overall below the average level with the coefficient of 0. 944 5,0. 995 4,0. 903 4 and 0. 944 7 respectively. Meanwhile, the comprehensive transportation cost from Waigaoqiao bo
