我国陆海经济耦合协调性的时空格局研究

On China’s Spatial and Temporal Patterns of Land and Marine Economy Coupling Coordination

本文以沿海11个省市为研究对象,基于物理学上耦合的概念,构建海洋经济与陆域经济的耦合协调度模型并对参数进行优化改进,对2006—2016年沿海11个省市的海洋经济发展与陆域经济发展之间的耦合协调度进行测算,进而基于时间和空间双重维度,提取我国陆海经济耦合协调性的时空格局演化特征。结果表明:从全国来看,我国陆海经济系统呈现出从濒临失调衰退到良好耦合协调的一种渐变过程,二者存在良性协同耦合发展关系;不同经济区之间陆海耦合协调度有所不同,其中长江三角洲耦合协调状态最好,珠江三角洲和环北部湾地区相对较弱。

Taking eleven coastal provinces and cities as research objects and based on the concept of coupling in physics,this paper not only builds a model of coupling coordination degree between marine and land economies,but also improves the parameters by means of optimization.Calculating the coupling coordination degree between the developments of marine and land economies of the eleven provinces and cities from 2006 to 2016,and then being based on the dual dimensions of time and space,we have extracted the evolutionary characters of spatial and temporal pattern of China's land-marine economy coupling coordination.The results show that,nationally speaking,China’s land-marine economy system has achieved a gradual process of transition from imbalanced recession to good coupling coordination.There exists a benign and coordinated development relationship between the two.But the coordination degree of land-sea coupling is different in different economic circles,of which the Yangtze River Delta is the best and the Pearl River Delta and the Beibu Gulf Rim are relatively weak in terms of coupling coordination state.
