中国沿海省域海洋经济与自由贸易试验区耦合协调发展研究

The Coupling and Coordinated Development of Marine Economy and Pilot Free Trade Zone in China’s Coastal Provinces

中国沿海11个省份既拥有“海洋经济”的区位优势,又具备设立“自由贸易试验区”的体制优势。为深入分析二者相互作用对于区域经济的影响,本文构建了11个省份“海洋经济发展状况”与“自贸试验区发展状况”之间的耦合协调发展模型。研究表明,耦合协调程度越高的地区经济发展水平就越高,论证了协调两大因素对沿海地区经济发展的重大意义。从8年来的模型耦合协调度均值0.7616来看,两者整体尚处于“中度协调发展”的程度,耦合度需进一步增强。同时还发现了较发达地区的海洋经济发展程度与经贸水平不匹配、新设自贸试验区省份的耦合发展水平受疫情冲击较大,以及作为自贸港的海南省耦合协调度处于全国最差水平等实际问题,并针对上述问题提出了政策建议。

China’s 11 coastal provinces have not only the regional advantage of“marine economy”,but also the institutional advantage of“free trade pilot zones”.In order to deeply study the impact of the two advantages’interaction on regional economy,this paper constructs a coupling and coordinated development model between“marine economic development”and“development of free trade pilot zone”in 11 coastal provinces of China.Our research shows that the higher level of coupling and coordination between the two a region has,the better economic development the region will enjoy.This paper demonstrates the great significance of coordinating the two factors to coastal economic development.As the model shows,the coupling and coordination coefficient in the past 8 years averages at 0.7616,which means the two are coupled and coordinated only to a medium extent and need to be improved.At the same time,it is also found that there is strong regional heterogeneity,the degree of marine economic development in more developed areas does not match the economic and trade level,the coupling development level of the newly established pilot free trade zone is greatly impacted by COVID-19,and Hainan free trade port is at the worst level in China.Therefore,this paper puts forward targeted countermeasures and suggestions on the basis of this analysis.
