Abstract : *(250~1000 words)

Multimodal transportation is one of the ways to improve logistics efficiency. Compared with water-highway combined transportation, water-rail combined transportation can reduce carbon emission largely .In this paper, we focus on ways to promote water-railway combined transport’s development.Port scale efficiency is one of the main factors affecting the development of water-railway combined transport. Domestic scholars put forward solutions such as building regional multimodal transport service platform and integrating port resources, but there are still problems such as excess capacity of adjacent ports and poor coordination of port and railway. In order to solve these problems, firstly this paper selects the port data of 31 cities in the middle reaches of the Yangtze River from 2012 to 2021. Based on the Moran's I index to test the spatial correlation, this paper constructs the Spatial Dubin Model(SDM) to analyze the spillover effect of port aggregation on Port scale efficiency ,and finds that the port spatial relationship in this region is relatively stable and  port scale efficiency’s significant role in improving the efficiency of multimodal transport. Besides, through investigating multimodal transport information service platform as well as Railway network and port distribution in the middle reaches of Yangtze River , the interaction information occlusion , low degree of docking between railway and port and other problems are found. In the following , corresponding suggestions on the above conclusions and problems are listed. This paper, based on the above research results, is expected to improve port scale efficiency thus to accelerate water-railway combined transport development.
