Research on Combined Optimization of Intercontinental Intermodal Transport Scheme by Railway Network and Double Difference Model

Abstract

The China-EU freight train is a physical link connecting the Eurasian continent in the new era and a new bridge for expanding China-EU economic and trade cooperation. Since its opening in 2011, China-EU freight trains have developed rapidly. Since 2015, it has been normalized and fixed, and now it has entered a stage of steady growth. Based on the trade gravity model, this paper calculates the trade gravity coefficients between China and the rest of the world in 2015 and 2019, and then establishes the analysis and construction of China-EU freight trains and cross-border transport models. The combined optimization of intercontinental transport scheme and regional transport scheme is constructed, which is composed of tractor, semi-trailer and intercontinental railway intermodal transport. The transport network of this model consists of two types of nodes: multimodal transport station and highway transport station. Based on the double difference regression analysis of gravity coefficient, it is concluded that the central attractiveness of trade between China and the rest of the world is relatively low in the past, but under the overall downward trend of trade attractiveness between China and the rest of the world, the China-EU train has significantly promoted the growth of trade in recent years, which is attractive.
