With the economic and social development and the changes in the demand for talents of employers, some colleges and universities are facing the requirement of transformation. Taking the overall transformation of Northeast Electric Power University’s international economics and trade majors into financial engineering majors as an example, this paper analyzes the main problems faced by the construction of the transformation majors, and puts forward the basic principles and basic ideas that the transformation majors should follow in the construction of the curriculum groups. The basic analysis framework for the construction of the transformation professional curriculum group and the results and effects of the construction of the curriculum group after the transformation of some majors are presented. The research conclusions not only have reference significance for the smooth transformation of the international economics and trade major into the financial engineering major through the construction and transformation of the course group, but also have certain reference value for the construction of the course group of other majors in colleges and universities.
