The Eco-Efficiency Evaluation on Petrochemical Industry Based on Three-Stage DEA Model

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.

The emerging ecological cost index (Cagno et al, 2012;Vogtländer et al, 2002) and the sociological method (Mickwitz et al, 2006) were also used in recent years.…”
