中国海洋经济高质量发展水平测度与差异分析

Measurement and difference analysis of high-quality development level of ocean economy of China

本文基于2011—2020年我国沿海11省(直辖市)的面板数据,从经济综合实力、科技创新程度、协调发展水平、可持续发展能力、对外开放水平和改善民生状况六个维度构建海洋经济高质量发展水平评价指标体系,运用AHP-熵权TOPSIS模型计算海洋经济高质量发展水平指数,探讨我国海洋经济高质量发展现状,并在此基础上采用泰尔指数和莫兰指数讨论海洋经济高质量发展水平的区域差异和空间相关性。结果表明:我国海洋经济高质量发展水平呈现波动上升趋势;海洋经济高质量发展水平总体差异的主要来源是区域内差异,其中南部海洋经济圈差异最为显著;我国海洋经济高质量发展水平存在显著的空间正相关性,高质量发展水平相当的省市在空间上呈现一定程度的集聚性。

Based on the panel data of ll coastal provinces(municipalities directly under the governance of central government)in China from 201l to 2020,we constructed an indicator system for high-quality development of ocean economy from six dimensions including comprehensive economic strength,degree of scientific and technological innovation,level of coordinated development,capacity for sustainable development,level of opening to the outside world and improvement of people's livelihood.We used the AHP-entropy weight TOPSIS method to calculate the high-quality development level index of the ocean economy,and discussed the current situation of the high-quality development of the marine economy of China.On this basis,the Theil index and Moran index were used to discuss the regional differences and spatial correlations of high-quality development of the ocean economy.We found that the high-quality development level of the ocean economy of China shows a fluctuating upward trend.The main source of the overall difference in the high-quality development of ocean economy was the regional difference,of which the difference in the southern ocean economic circle was the most significant.There was a significant spatial positive correlation between the high-quality development level of the ocean economy of China,and the provinces and cities with the same high-quality development level showed a certain degree of agglomeration in space.
