江苏省城市化与海洋经济耦合协调发展研究

The Coupling and Coordinated Development of Urbanization and Marine Economy in Jiangsu Province

城市化与海洋经济相互作用和相互影响,二者的协调发展对于促进社会经济可持续发展具有重要意义。文章在阐述耦合作用机制的基础上,构建江苏省城市化和海洋经济系统综合评价指标体系,利用变异系数法、综合评价函数和耦合协调度模型对二者的综合发展水平和耦合协调度进行实证分析,并提出发展建议。研究结果表明:科技发展水平、就业结构、交通运输能力、居民消费水平以及投资规模和经济发展水平是影响城市化发展的重要因素,海洋生态环境对海洋经济发展的影响较大;2006-2019年江苏省城市化和海洋经济的综合发展水平和耦合协调度均有所提升,耦合协调发展从濒临失调逐渐转为良好协调,但海洋经济综合发展水平仍较低且严重滞后于城市化发展水平;在未来的发展中,应大力推动空间城市化、加快海洋产业结构优化以及发挥陆海产业联动作用。

Urbanization and marine economy interact and influence each other. The coordinated development of the two is of great significance for promoting the sustainable development of social economy. On the basis of expounding the coupling mechanism, this paper constructed a comprehensive evaluation index system of urbanization and marine economic system in Jiangsu Province, and made an empirical analysis of their comprehensive development level and coupling coordination degree by using the variation coefficient method, comprehensive evaluation function and coupling coordination degree model, and put forward development suggestions. The results showed that the development level of science and technology, employment structure, transportation capacity, residents′ consumption level, investment scale and economic development level were important factors affecting the development of urbanization, and the marine ecological environment had a greater impact on the development of marine economy.From 2006 to 2019, the comprehensive development level and coupling coordination degree of urbanization and marine economy in Jiangsu Province had been improved, and the coupling coordination development had gradually changed from being on the verge of imbalance to good coordination, but the comprehensive development level of marine economy was still low and seriously lagged behind the urbanization development level.In the future development, spatial urbanization should be vigorously promoted, the optimization of the marine industrial structure be sped up and should the role of land and sea industries be given play to.
