Application of principle component analysis to build provincial eco efficiency index for Binh Duong province from 2001-2012

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. | Journal of Science and Technology 54 (2A) (2016) 251-258 APPLICATION OF PRINCIPLE COMPONENT ANALYSIS TO BUILD PROVINCIAL ECO-EFFICIENCY INDEX FOR BINH DUONG PROVINCE FROM 2001-2012 Doan Ngoc Nhu Tam1, *, Che Dinh Ly2 1 Institute for Computational Science and Technology, Ho Chi Minh City, Vietnam Faculty of Environment, University of Science, Vietnam National University Ho Chi Minh City, 227 Nguyen Van Cu, District 5, Ho Chi Minh City, Vietnam 3 Center of Water Management and Climate Change, Ho Chi Minh City, Vietnam 2 * Email: tamdnn@tdmu.edu.vn Received: 5 May 2016; Accepted for publication: 26 June 2016 ABSTRACT 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. Keywords: Regional Eco-Efficiency, Eco-efficiency Synthetic Index, Socioeconomic development index (SDI), Resource consumption index (RCI), Environmental Pressure index (EprI), Principle component analysis (PCA). 1. INTRODUCTION “Eco-efficiency” is built by the World Business Council for Sustainable Development (WBSCD) in the early 1990s. Eco-efficiency is a useful tool for managing and evaluating the effectiveness between economic income and resource consumption and .
