RELATIONSHIPS BETWEEN QUALTTY OF SUFACE WATER ENVIRONMENT AND GDP PER CAPITA IN BINH DUONG PROVINCE FROM 2000 TO 2011
Che Dmh Ly^
Summary
This paper investigates the relationship between surface water quality and economic growth in Binh Duong province based on the environmental Kuznets curve hypothesis (EKG), using t h e surface water monitored data over 2000-2011. Research data sources from Binh Duong Environmental Monitoring Center from 2000 to 2011 on environmental monitoring data of seven main sfreams and rivers. Economic fector used is gross domestic product per capita by comparative pnce. T h e r e are four of economy-environment relationships in the studied period in Binh Duong: NH3-N, COD, Coliform and Nemerow pollution Indices. Regression method of "Fit Line Plot" procedure h a s been used to fit the data. Linear, quadratic and cubic form were tested and logarithm Neper form has been shown highest relation coefficient T h e results also show that surface water indicator supports EKC good in case of Binh Duong and this province h a s e x p e n e n c e d the polluted peak and surface water quahty gradually improved.
Key word: Kuznet curve, environmental economy, sueface water quality, Binh Dirong, environmental quality.
