Study on the Coupling Coordination Degree of Marine Economy and Regional Economy in Zhejiang Province

Abstract

Based on the existing research results, the evaluation index system of marine economy and regional economic development of Zhejiang Province was established. The relevant data of marine economy and regional economy of Zhejiang Province from 2011 to 2020 were taken as the research objects, and the comprehensive weight and comprehensive evaluation score were calculated using AHP and entropy method. The degree of coordination between marine economy and regional economy development and the main limiting factors were analyzed by coupling coordination degree model and obstacle degree model. The results show that the overall change trend of the comprehensive evaluation scores of marine economy and regional economy subsystems is consistent, and the comprehensive development level of marine economy is better than that of regional economy. The coupling level between subsystems is generally high, and the coordination level is constantly improved, but the coordination degree is not high. The key factors affecting the coordinated development of marine economy and regional economic system are the proportion of marine research and development (R&D) expenditure to the gross marine product, the proportion of R&D expenditure in GDP, the proportion of marine tertiary industry to marine secondary industry, the proportion of regional GDP to national GDP, the number of patents granted and the growth rate of added value of marine tertiary industry. Based on this, relevant policy suggestions are put forward to provide guidance for the high-quality marine economy of Zhejiang Province to promote regional development.
