Abstract: Represented by the massive open online courses with the convenience of online learning at all times and places, the curriculum selection diversity, the lectures authority, the network course learning mode has attracted more and more attention. In this paper, structural equation model was introduced, according to the characteristics of the research object, to test the model of the determinants of students' participation in network courses. Using STATA12.0, this paper makes an empirical analysis to obtain the path coefficients, which shows that transaction costs, transaction value and transaction risk have significant effects on students' participation in network courses. Finally, some effective measures of improving students' participation in network courses are proposed from the aspects of platform administrators, course providers, government and schools.
