Evaluating Transportation Routes Between China and Vietnam Based on Delphi–CFPR

China-Vietnam trade significantly grows in the recent decades, and their trade value in 2019 arrives at approx. 117 billion USD. The fast growth trade stimulates the development of the transport infrastructure and new routes between two countries. Currently the China-Vietnam trade is implemented by road, rail, water, air and intermodal transportation. To respond to the strong demand of trade and taking into account the significant role of containerization in international trade, selecting an efficient intermodal route becomes necessary. This study aims to evaluate the competitive routes for 40 ft container transportation between China and Vietnam through an empirical study investigating the routes between Chongqing, China and Haiphong, Vietnam. A hybrid Delphi and CFPR method is applied with the support of quantitative and qualitative data to obtain the goal from logistics service provider and shipper’s perspectives. The results reveal that among the eight main factors, transportation cost is the most important influencing route choice for 40 ft containers. Moreover, the eight multimodal routes from Chongqing to Haiphong are evaluated to have the best route identified as aviation. This research will benefit policymakers and state institutions by the provision of the available routes and their advantages against each key criterion. Furthermore, this research provides useful insights for logistics companies and shippers in transporting cargoes from China and Vietnam.
