Keywords:Regional Eco-Efficiency, Eco-efficiency Synthetic Index, Socioeconomic development index (SDI), Resource consumption index (RCI), Environmental Pressure index (EprI), Principle component analysis (PCA).
Based on a proposed concept of Regional Eco-Efficiency of Zhou Zhenfeng, a set of indicators for assessing, eco-efficiency of provincial level has been conducted. Set of indicators included 26 indicators, and was divided into 3 groups: Socio-Economic Development Index (SDI) (9 indicators); Resources Consumption Index (RCI) (7 indicators) and Environmental Pressure index (EPrI) (10 indicators). Principle component analysis (PCA) was used to assess Eco-efficiency Synthetic Index (ESI) of Binh Duong province in the 2001-2012. Results shown that the ESI of Binh Duong province has been clearly improving from 2001-2012. RCI and EPrI respectively had a significant correlation with SDI. Results also have been shown that the industrialization generated waste and if the pollution control solution is not effectively so environmental pressure is continuously increase and degrade the environment.
