| Summary: | In order to solve the problems of high energy consumption, low efficiency and serious pollution in petrochemical industry, based on the theory of circular economy, the operation system of circular economy model in petrochemical industry is analysed. Then, the material flow analysis method is introduced, and its meaning and basic framework are explained. Finally, combining with the material flow characteristics of petrochemical industry, the basic framework and specific index content of the circular economy evaluation index system of petrochemical industry are established. It is suggested that petroleum chemical industry should strengthen the development of circular economy. The results show that the evaluation index system of circular economy not only embodies the quantitative index, but also takes into account the efficiency index. Therefore, it is in line with the concept of circular economy.
