Efficiency Evaluation of Chinese Provincial Industrial System Based on Network DEA Method
نویسندگان
چکیده
The operation process of the Chinese provincial industrial system consists four stages, namely production (P) stage, wastewater treatment (WWT) solid waste (SWT) and sulfur dioxide (SDT) stage. Based on this structure, a four-stage data envelopment analysis (DEA) model is developed to evaluate eco-efficiency, efficiency, efficiency systems in China, considering undesirable output variable returns scale (VRS). objective from 2011 2015, following conclusions are drawn: Firstly, eco-efficiency has not been significantly improved during study period, average score low, only 0.3805. Secondly, reasons for low different Eastern, Central, Western, Northeastern regions. Thirdly, compared with P WWT SWT SDT stage still relatively weak.
