基于港城可达性的辽宁沿海港口腹地市场潜力分析

Analysis of Liaoning Coastal Port Market Potential Based on City and Port Accessibility

基于GIS平台,通过加权平均旅行时间模型测算辽宁省沿海港口的港城可达性。基于港城可达性,对港口的腹地市场潜力进行了相关探讨。结果表明:1六大港口港城可达性呈现"n"型,中部的营口港、盘锦港可达性最高,右翼的大连港、丹东港可达性最低,可达性绝对优势使盘锦港和营口港成为辽宁省大多数城市货物运输的首要选择。2大连港的市场潜力最大,营口港、锦州港次之;大连港的城市本地市场占据主要份额,锦州港、营口港、丹东港内外市场相对均匀,葫芦岛港和盘锦港外部市场份额相对较大。3各港口腹地市场潜力存在明显空间竞争关系,葫芦岛港和锦州港主要市场区域出现重合;营口港和盘锦港竞争区域主要集中在辽中区域,沈阳是六大港口的重要青睐地。

Based on the GIS platform, this paper estimated the reachability that cities in Liaoning Province to the port by modified weighted averge travel time model, and through the establishment of the pert market potential model and the port competitiveness index model to analyze the 6 port aarket potential and competitiveness level. The results showed that：①The level of 6 pert cities accessibility along the Bohai Sea circle clockwise inveted ＂n＂ type,Yingkou port and Panjin pert up to most, Dalian, Dandong port up to weakest.The absolute advantage of accessibility made Panjin and Yingkou port become the primary choice for most city transportation. ②Dalian pert was the largest potential market, Yingkou port, Jinzhou pert, Panjin port times, Dalian port city local market occupyed major share, Jinzhou pert, Yingkou, Dandong port and international market was relatively homogeteous, Huludao pert and Panjin pert external market share was relatively large. ③There was an obvious competition in the pert market, Huludao pert ~nd Jinzhou pert major market areas appeared coincident. Yingkou pert and Panjin port regional competition mainly concentrated Liaozhong area.Coastal cities in Dalian, Yingkou, Panjin internal market port competition was obvious, Shenyang was the important favor of the 6 major ports.
