Research on the linkage mechanism and influencing factors of Jiangsu inland shipping and regional economic system

Abstract

In order to cater to the new development paradigm, it is increasingly important of inland shipping system to expand domestic demand. Based on the linkage mechanism between inland shipping and regional economy, the index system of coordinated development is constructed, then the coupling coordination degree model of each index weight determined by entropy weighting method is calculated, the coupling correlation degree and coupling coordination scheduling between Jiangsu inland shipping system and regional economy system from 2009 to 2019 are enumerated, the key factors causing coupling effect in the two systems are analyzed by grey correlation analysis at the last. The result shows that the coupling between inland shipping and regional economy in Jiangsu Province has been at a high level for a long time, and the coupling coordination level has experienced a change from maladjustment to benign coupling, showing a trend of steady progress. Container throughput, cargo throughput, iron ore throughput, coal and its products throughput, GDP and per capita GDP are the key factors of the interaction between inland shipping and regional economy in Jiangsu Province. By revealing the linkage mechanism between inland shipping system and regional economic system, some suggestions to promote the coordinated development of regional systems can be put forward.
