Research on the Coordinated Development of Coastal Port Logistics and International Trade: Based on Six Coastal Provinces of China

As an important channel for international trade cargo transportation, the logistics development level of coastal ports is a key factor to promote the growth of international trade. Strengthening the coordinated development of coastal port logistics and international trade will help promote the sustainable development process of countries (regions). Based on this, this paper explores the sustainable development of coastal port logistics and international trade. Taking six coastal provinces (cities) in China as samples, by analyzing the index data of each subsystem from 2016 to 2020, the entropy weight method is used to calculate the weight of each index, and the coupling coordination model of coastal port logistics development and international trade is constructed to explore the coordinated development degree. Through empirical analysis, it is proposed to strengthen the infrastructure construction of coastal ports, promote low-carbon operations, improve the optimal allocation of resources, and deepen the development of cooperation with coastal ports in importing and exporting countries. The results show that the coordination degree of China's coastal port logistics and international trade development has great regional differences. Shanghai and Zhejiang Province have been at a good level of coordinated development in recent years, while the coordinated development degree of Liaoning Province and Tianjin is in the reciprocal position.
