With the growth of the economy, the competition for talents has become the competition of international resources. Moreover, the core of competition is innovative talents, and the main factor of talent competition is the education model. It is well known that higher education is a key stage of talent growth, and its internationalization would become an inevitable trend. The basic theme of current education is to promote the internationalization of education and cultivate innovative talents, so as to realize ecological sustainability. However, the current traditional training model has many shortcomings, especially the talent training system and training objectives, which hinder the internationalization of education. In addition, in the training mode of innovative talents, to a certain extent, the development of the overall quality of talents is limited. Therefore, this paper has studied the importance of sustainable talent cultivation in an ecologically sustainable environment through the establishment of international education and innovative talent cultivation models. The results have shown that under the development of international education, the overall quality of innovative talent training has increased by 3.6% compared with traditional talent training, and the training effect has increased by 5.4%.
