连云港市的港-城协调发展模式演化及影响要素

港口与城市之间的协调发展是实现港城互动、提升港口城市竞争力的重要途径。以连云港市1989—2009年统计数据为基础,构建了港口与城市协调发展的综合评价指标体系,运用因子分析方法计算出两系统综合发展指数;结合协调度、静态和动态协调发展度,对连云港港口与城市的协调发展模式的演化轨迹进行评价和分析。结果表明:①1989—2009年,连云港市港—城协调发展模式总体上经历了濒临失调模式到勉强协调模式再到基本协调模式的演化过程;②港口与城市基本处在协调发展的轨迹上,动态协调发展度呈逐渐增长的态势。进一步分析认为协调发展模式的演化主要由港口功能的升级、临港产业的壮大、城市发展的支撑等推动以及自然环境和区位因子、腹地的经济水平、周边港口的空间袭夺、港城关系的空间分离等约束要素共同作用。

EVOLUTION OF THE COORDINATED DEVELOPMENT MODE OF PORT-CITY AND ITS IMPACTS IN LIANYUNGANG

Because of the rapid development of the world economic globalization,the situation that global economic barycenter transfers to the coastal port cities is becoming more and more obvious.Coordinated development of port and city is a crucial way to achieve the port-city interaction and enhancing the comprehensive competitiveness of the port city.As a result,to analyze the relationship between the two has been one hot spot of many geographical scholars at home and abroad.Based on the statistical data from 1989 to 2009 of Lianyungang city in Jiangsu province,which is a typical representative of ’Economic depression’ in eastern coastal areas,a comprehensive evaluation index system containing six aspects of port and other ten aspects of city was setting up to estimate the coordinated development of port and city,and then the comprehensive development index of the two systems was calculated with the help of the method of factor analysis.The results show that the general process of coordinated development mode of Lianyungang has experienced three evolutionary processes in the studied period there are near offset mode,barely coordination mode and basic coordination mode.In addition,the degree of dynamic coordinated development between the two is on the rise,and the track of the port and city development wan basically coordination.In the future,the mode will gradually tend to coordinated.Through the further analysis,the paper reveals that the main factors which result in the evolution of Lianyungang’s port-city coordinated development mode are as follows: the international situation,the state and local government policy;port’s own infrastructure construction,locational and natural conditions;port-vicinity industrial development and urban economic support;the economic level of the hinterland and the competition of its surrounding ports,etc.
