Evaluation of logistics and port connectivity in the Yangtze River Economic Belt of China

The very uneven development of ports along the Yangtze River Economic Belt in China makes ports a specific case study of a general phenomenon in the analysis of inter-port connectivity. This study evaluates the actual connectivity of ports and logistics in the Yangtze River Economic Belt of China by developing a comprehensive model with an integrated index. This comprehensive model uses an improved gravity model to develop and extend from the analysis of port-water transport network connectivity to the port-inland hinterland logistics connectivity, and unearths the key factors that affect the port-water and port-hinterland connectivity. The results show that the port connectivity in the lower reaches of the Yangtze River is generally better than that of the middle and upper reaches, whether port-water or port-inland hinterland. Port connectivity has core-periphery characteristics, but Chongqing port is an exception in the results of port-water transport network connectivity. Because Chongqing port is in a leading position in the comprehensive development strength and hinterland economic development of ports in the upper reaches of the Yangtze River, but its water transport network connectivity is not the best. In the final analysis of the research results, this study presents some corresponding policy recommendations.
