中国海洋经济包容性与效率的协同关系

Synergistic Relationship Between Inclusiveness and Efficiency of China's Marine Economy

海洋经济包容性与效率是高质量发展的两个重要特征,二者间关系的探究对促进我国海洋经济高质量发展具有重要意义。利用TOPSIS-VIKOR模型和超效率SBM模型分别对我国沿海省域2008—2020年海洋经济包容性水平及其效率进行量化测度,然后应用哈肯模型探究两者之间的协同关系。结果显示:(1)2008—2020年我国沿海地区海洋经济的包容性水平总体呈波浪式上升的发展态势;(2)海洋经济包容性是主宰海洋系统演化的序参量,其与效率的相互作用具有中等偏强的协同增效应,且经历了从低级到中级再到高级阶段的系统演变;(3)沿海各省域间海洋经济包容性与效率的协同演化存在较大差异性,且根据其协同类型可分为集中型和分散型两大类;(4)面对新冠肺炎疫情的负面冲击,辽宁、江苏和广西三省区的协同水平明显下降且分别成为我国沿海三大区域的薄弱点。

The inclusiveness and efficiency of marine economy are two important characteristics of high-quality development,and the exploration of the relationship between the two is of great significance to promote the high-quality development of China's marine economy.This paper uses the TOPSIS-VIKOR model and the super-efficient SBM model to quantitatively measure the inclusiveness level and efficiency of marine economy in coastal provinces in China from 2008 to 2020,and then applies the Haken model to explore the synergistic relationship between the two.The results show that:1)From 2008 to 2020,the inclusive level of marine economy in China's coastal areas generally showed a wave-like upward development trend.2)The inclusiveness of the marine economy is the sequential parameter that dominates the evolution of the ocean system,and its interaction with efficiency has a moderately strong synergistic effect,and it has experienced the evolution of the system from low stage to intermediate stage to advanced stage.3)There are large differences in the co-evolution of marine economic inclusiveness and efficiency among coastal provinces.According to the synergy type,it can be divided into two major categories:centralized type and decentralized type.4)In the face of the negative impact of the COVID-19,the synergy level among Liaoning,Jiangsu and Guangxi provinces has significant declined and become the weak points of the three major regions on the eastern coast of China,respectively.The results of this study can provide a reference for promoting the steady improvement of the quality and reasonable growth of China's marine economy.
