Students form six competing simulation enterprises, which operate for 5-6 years. Through the participation of students-> Sand table carrier->; Simulation management-> Confrontation drill->; Lecturer comments-> A series of experimental links, such as students' perception, and the design ideas of combining theory with practice and role-playing with post experience, enable students to understand scientific management rules, cultivate team spirit and comprehensively improve management ability in a series of activities such as analyzing the market, formulating strategies, marketing planning, organizing production and financial management.
