Major crises such as greenhouse effect and resource depletion remind people that environmental protection is imminent. However, the economic growth is always accompanied by the destruction of the environment, so the development of green industry economy is very necessary for the balance between the two. However, many of today’s green industry economic development is still in the theoretical stage, and there are no substantive measures. Therefore, this paper aims to build a reasonable development evaluation model for the green industry economy, and use the results of the model to explore the sustainable development of the green industry economy. In view of this, in the stage of proposing the model, this paper refers to a large number of literature and field investigation, and selects 30 suitable evaluation indexes. The experimental results of the green industrial economy in Sichuan Province with the designed model show that the comprehensive evaluation index of green economic development has increased steadily. It reached 0.8255 in 2016, which is in line with the actual situation. This shows that the model in this paper has a good fitting effect, and can provide guidance for the economic development model and effective path of green industry.
