UNCTAD框架下的长江经济带港口代际识别与战略响应

阐释了长江经济带港口代际识别的意义和UNCTAD框架下港口代际识别的标准。运用模糊模式识别的方法对长江经济带主要港口进行代际识别测度,并对初步识别结果做进一步分析和修正。研究表明:①长江经济带港口代际等级总体上较低,大多数处于UNCTAD框架下的第一代港和第二代港水平;②不同代际港口在空间上呈现出明显的东西分异特征,港口代际等级和港口分布密度由东向西均表现出显著的下降趋势;③从局部空间看,不同等级的港口在地理分布上呈现出一定的"省域化"特征,即在省域范围内形成以一两个高等级港为中心、其他低等级港为支线港、喂给港的港口群形态。根据研究结论,提出长江经济带建设下的港口战略转向:充分认识港口在长江综合运输体系中的作用;有序推进长江经济带港口代际更替;以港口群的形式推进港口建设和适时推进长江沿岸自贸区建设。

RECOGNIZING PORT GENERATIONS IN YANGTZE RIVER ECONOMIC ZONE AND ITS STRATEGIC TRANSFORMATION UNDER THE FRAMEWORK OF UNCTAD

The paper defined the significance of recognizing port generations in Yangtze River Economic Zone and illustrates the criterion of recognizing port generations under the framework of UNCTAD. Then, the article studied the port generations in Yangtze River Economic Zone (YREZ) based on the method of fuzzy pattern recognition. The results showed as follows. ①The generational grade are low on the whole, and most ports in YREZ belong to the first or second generation port. ②Both of the generation grade and the distribution density of ports present a trend of decreasing from east to west. ③From the perspective of local space, different types of ports show provincial character in the geographical distribution. That is, port cluster consisting of 1 or 2 high-grade ports and several low-grade ports as lateral ports or feeder ports are appearing within the scope of province. According to the research conclusion, we propound the new strategic transformation on port development under the construction of YREZ: fully realizing the important function of ports in the Yangtze River comprehensive transportation system, orderly prompting the upgrade of port generation, propelling the advancement of port cluster and impelling the construction of free trade area in due time.
