港口由于地理位置的不可移动性,自然条件决定了其服务范围的大小。其内在的发展主要是依靠腹地经济的发展,即其服务区域的经济发展情况。比如,上海港的腹地就是华东地区以及沿长江流域地区;环渤海港口的腹地则是东北、华北等地区。腹地的产业情况、工业增长和经济发展情况直接关系到了港口货物的来源和吞吐量的增长。 Due to the immigration of the port, natural conditions determine the size of its service area. Its internal development relies mainly on the economic development in the hinterland, that is, the economic development of its service areas. For example, the hinterland of Shanghai Port is the east China and the Yangtze River valley; the hinterland of the Bohai Sea Rim is the northeast and north China. The industrial situation in the hinterland, industrial growth and economic development have a direct bearing on the source and throughput of port goods.
