In order to meet the urgent need of international engineering talents for the development of Chinese transportation construction enterprises going abroad, Chongqing Jiaotong University has carried out 10 years of exploration and practice of university-enterprise cooperative training mode with industrial enterprises. Based on the three dimensions of "engineering knowledge, engineering practice and engineering management" of international engineering talents, the university has built "Overseas Class", "International Engineering Class" and "Cross-border Composite Experimental Class", which are customized in short term, systematic in long term. Diversified school-enterprise education modes such as "Overseas Class" for short term customization, "International Engineering Class" for long term system and "Cross-border Compound Experimental Class" have been built for flexible setting. Through cooperatively recruiting?students, designing course program, presenting courses or lectures, organizing academic?competitions, guiding graduation practice and evaluating training quality, the mutual benefit and win-win cooperative education long-acting mechanism has been built. More than 3500 graduates have been supplied to CCCC ( China Communications Construction Company ), CREC (China Railway Engineering Corporation ) and CRCC (?China Railway Construction Corporation) to meet the needs of the internationalized, diversified and high-quality talents for “one belt and one road” traffic construction projects.
