Abstract: Previous research on the evaluation of production efficiency cannot effectively respond influences caused by environmental effect and random error. Specifically, most of electric power companies in China suffer from low production efficiency and ineffective evaluation models. However, with the adoption of the proposed three-stage data envelop analysis (DEA) model, reasonable judgments on the investment decision and management level can be reached. Practical investigation has proved that it can help power companies make more objective judgment which would then bring about continuous improvement.

Abstract: Petrochemical industry produces long-lasting industrial waste gas, waste water and waste residues which affect ecological environment in our country seriously. The eco-efficiency rate is a significant indicator in evaluation industrial sustainable development, which represents the efficiency of alleviation pressure on the environment using natural resources in the economic growth. In this paper, we used three-stage DEA model to evaluate the eco-efficiency of the petrochemical industry. The empirical analysis shows that it is feasible to use the three-stage DEA model on evaluation the eco-efficiency of the petrochemical industry. The conclusion is has a practical and theoretical significance to promote sustainable development level of petroleum enterprise.

Abstract: As a main industry of our national economy, petrochemical industry produces long-lasting industrial waste gas, waste water and waste residues which affect ecological environment in our country seriously. The eco-efficiency rate is a significant indicator in evaluation industrial sustainable development, which represents the efficiency of alleviation pressure on the environment using natural resources in the economic growth. So, in this paper, we used three-stage DEA model to evaluate the eco-efficiency of the petrochemical industry. The empirical analysis shows that it is feasible to use the three-stage DEA model on evaluation the eco-efficiency of the petrochemical industry.
