Abstract

The coordinated development of coastal ports and urban economy has great significance to realize the high-quality development of marine economy. Under the requirements of high-quality development, this article theoretically analyzes the interactive relationship between port economics and urban economics, then based on the data envelopment analysis (DEA), static coordination degree model, and dynamic coordination degree model, constructs the vertical evaluation index system and evaluation model to evaluate the coordinated development level of port economics and urban economics, and evaluates the actual situation of the three coastal cities of Jiangsu province as an example. The results show that the average effectiveness ranking of the coastal ports to urban economics is the same as that of urban economics to coastal ports, but the degree of impact varies from region to region, and the degree of coordination follows a phenomenon of Lianyungang >Nantong >Yancheng. Finally, the article gives strategic suggestions to promote the high-quality development of the three coastal cities in Jiangsu Province.
