The construction of ecological civilization and sustainable development has been paid more and more attention by China, and green education (GE) has become an important part of university education. Green development and lifestyle have become an inevitable trend. Strengthening GE for university students and helping them establish green management (GM) awareness have become important measures to implement the national strategy of “ecological priority and green development”. Many Chinese universities are also actively promoting green management education (GME), and these measures of GME influence university students’ awareness of GM and strengthen the action process and mechanism of their green behavior (GB), which need to be further clarified. Therefore, Chinese university students studying at schools of economic and management of agriculture and forestry universities were taken as the research objects, and based on Theory of Planned Behavior (TPB), a model of the effect of GME on university students’ GB is established to deeply explore the path and effect, which provides decision-making reference for universities to carry out GME in depth.
