广西北部湾海洋经济、社会与生态系统耦合协调度研究

Study on the Coupling Coordination Degree of Marine Economy,Society and Ecosystem in Beibu Gulf of Guangxi

近年来,广西加速发展海洋经济,不断推动海洋社会发展,同时又要保护海洋生态环境。因此,研究广西海洋经济、社会与生态系统耦合协调发展具有重要的现实意义。本文基于2005~2021年广西北部湾经济区北海、钦州、防城港的海洋经济、社会和生态环境相关面板数据,首先,构建了广西海洋经济、社会和生态环境三系统的综合评价指标体系,采用熵值法和TOPSIS法得到其综合评价指数。在此基础上,利用耦合协调度模型对广西北部湾海洋经济、社会和生态系统的耦合协调发展进行实证研究。结果发现:广西北部湾海洋经济、社会与生态系统综合评价指数总体上逐年增加,广西北部湾海洋经济、社会和生态系统两两之间及三者之间耦合协调水平均由低中度协调发展为良好协调。最后,提出了一些政策性建议。

In recent years,Guangxi has accelerated the development of marine economy,constantly pro-moted the development of marine society,and at the same time protected the marine ecological environment.Therefore,it is of great practical significance to study the coupling and coordinated development of marine economy,society and ecosystem in Guangxi.Based on the panel data re-lated to marine economy,society and ecological environment of Beihai,Qinzhou and Fangcheng-gang in Guangxi Beibu Gulf Economic Zone from 2005 to 2021,this paper firstly constructs a com-prehensive evaluation index system of marine economy,society and ecological environment of Guangxi,and adopts entropy method and TOPSIS method to obtain its comprehensive evaluation index.On this basis,the coupling coordination degree model is used to study the coupling and coordination development of marine economy,society and ecosystem in Beibu Gulf of Guangxi.The results showed that the comprehensive evaluation index of marine economy,society and eco-system in Guangxi Beibu Gulf increased year by year,and the coupling coordination level between the two and the three developed from low to moderate coordination to good coordination.Finally,some policy suggestions are put forward.
