Measurement and regional difference research on high-quality development of marine economy in China's three major marine circles
This article constructs a comprehensive evaluation index system for the high-quality development level of marine economy in coastal provinces and cities in China from five dimensions:innovation,coordination,green development,openness,and sharing.Based on panel data from 11 coastal provinces and cities(except for Hong Kong,Macau,and Taiwan,the same applies below)from 2011 to 2020,the Entropy Method is used to measure the comprehensive index and five sub-system indices of the high-quality development level of marine economy in coastal provinces and cities in China.Combined with the Dagum Gini Coefficient,the article further reveals the temporal and spatial differences in the high-quality development level of marine economy in China's 11 coastal provinces and cities.The study finds that,from the perspective of temporal evolution characteristics,the high-quality development level of marine economy in coastal provinces and cities of China,whether in terms of overall scores or sub-scores,shows an upward trend overall.From the perspective of spatial differentiation characteristics,there are significant regional differences in the high-quality development level of marine economy in China,and these differences mainly originate from within-region differences.Specifically,the within-region difference is the largest in the southern marine circle and the smallest in the eastern marine circle.
