After the pandemic, education will not go back to a 100% offline mode since the application of e-learning technologies (ELTs) cannot be avoided. Therefore, their impact should be studied for future education development. Most future entrepreneurs are attending school today. Therefore, universities need to supply necessary education to encourage students to cope with future conditions and development. At the same time, due to the increasing attention being paid to the harmony between ecology and prosperity, the sustainability aspect of entrepreneurship education needs to be emphasized as well. This study investigates the impact of ELTs on entrepreneurial education performance (including personal skills, product skills, and business skills), sustainability efficacy, and their impact on sustainability awareness. Data were collected from a master’s degree class on entrepreneurship at a Hong Kong university and SmartPLS was used to analyze the data. It was found that ELTs have a significant relationship with entrepreneurial performance and sustainability efficacy. Meanwhile, sustainability efficacy also has a significant relationship with sustainability awareness. However, no significant relationship between entrepreneurial skills and sustainability awareness was identified. The results indicate that ELTs can improve students’ entrepreneurial skills and sustainability awareness, which proves the effectiveness of ELTs and provides support for their application in future entrepreneurship education.
