The results show that teachers’ industry development has a significant direct effect on vocation teachers’ teaching  pro-industry demand, and pro-industry self-efficacy has a significant effect on  pro-industry teaching demand through industry development. The influence pattern and empirical data of pro-industry self-efficacy and industry development on  pro-industry teaching demand has a good fit.
