| 摘 要： | 为探究中国沿海港口经济发展过程，运用动态熵权TOPSIS法和GIS研究2000—2018年港口经济发展的演变特征，并采用Jenks自然断裂法进行空间层次划分。结果表明：不同时期各港口经济发展差异显著，近年来环渤海港口发展减缓，东南和西南沿海港口发展良好，呈南强北弱特征；港口经济发展在空间上呈整体分散、局部连片集中的分布格局，港口群内核心港口发展放缓，边缘港口发展势头强劲。根据港口经济发展综合值和指标体系各子系统对港口发展的贡献度值，将港口划分为5个层次和5种类型；将两种划分方式加以组合来识别各港口所属的层级地位和最优发展类型。

| Abstract: | In order to explore the economic development process of Chinese coastal ports, the dynamic entropy TOPSIS method and GIS are used to study the evolution characteristics of the port economic development in 2000 2018, and the Jenks natural fracture method is used to divide the spatial hierarchy.The results show as follows.There are significant differences in port developmentin different periods. In recent years, the development of the ports around Bohai Sea slows down, and the southeast and southwest coastal ports develop well, showing a south strong and north weak characteristic. In space, the development of port economy is scattered overall and concentrated locally, the development of core ports in a port group slows down, and the development of marginal ports is strong.According to the comprehensive value of port economy development and the contribution of each subsystem to port development in the index system, the ports are divided into five spatial levels and five types. The two division methods are combined to identify the hierarchical status and the optimal development type of each port. |
