在RCI指数的基础上,采用综合指标构建模型,并对我国长江中游沿岸重要港口城市近十年的发展态势进行了印证。长江中游沿岸港口城市岳阳市、武汉市和安庆市为城市发展水平略高于港口发展水平的临江城市,荆州市、宜昌市、芜湖市和马鞍山市为港城关系相对平衡的典型港城,黄石市、九江市、池州市和铜陵市为港口特征明显的门户城市。近10年间,岳阳市由典型港城转变为临江城市,黄石市和九江市由典型港城转变为门户城市,其他各市类型不变。
Based on the RCI index, a comprehensive index is used to build the model and the development trend of the past ten years in major port cities along the middle reaches of the Yangtze River in China is confirmed. Yueyang City, Wuhan City and Anqing City, which are the port cities along the middle reaches of the Yangtze River, are the cities of Linjiang City whose development level is slightly higher than the port level. Jingzhou City, Yichang City, Wuhu City and Ma'anshan City are typical port cities with relatively balanced relationship between them. Huangshi City, Jiujiang City, Chizhou City and Tongling City, port features obvious port city. In the past 10 years, Yueyang City has been transformed from a typical Hong Kong city into a city of Linjiang. Huangshi City and Jiujiang City have been transformed into port city from a typical Hong Kong city, while other cities and cities have remained unchanged.
