Abstract: The eight cities along the Yangtze River in Jiangsu province are important transportation nodes in the Yangtze River Delta, and their port efficiency has important research significance. According to the port background and data statistics, the factor analysis method was used to obtain three input indicators, including economic input, infrastructure construction and intermodal facility construction. And then the DEA game cross efficiency model was used to measure the port efficiency and analyze its space-time characteristics. Finally, spatial Durbin model (SDM) was used to furtherly analyze the spatial effect between port efficiency and influencing factors. The efficiency measurement research results show that the efficiency values of the eight ports along the Yangtze River in Jiangsu province from 2012 to 2019 fluctuate in time, with an overall upward trend; spatially, they are high in the middle and low on both sides. Global spatial autocorrelation analysis shows that the port efficiency has a significantly negative spatial correlation. The SDM analysis results show that the port efficiency of the eight cities along the river is positively correlated with the input of economic resources and the construction of intermodal facilities, and negatively correlated with the port infrastructure and the efficiency of surrounding ports.
