Software engineering economics is an important professional course of software engineering. This course focuses on improving students' economic ability and awareness of analyzing software projects. However, the current teaching methods of engineering economics are limited to theoretical teaching, lacking experimental links, and failing to achieve the expected teaching effects. In order to meet the needs of the new engineering teaching reform of software engineering major, this paper proposes a teaching framework for the experimental links of software engineering economics, and introduces the experimental teaching reform process of software engineering economics from the experimental items, experimental content and requirements. Practice shows that the combination of theory and experiment can improve students' understanding of teaching content, increase their interest in learning courses, and enhance their ability to use economics to analyze and process software projects.
