A new model concerning the relationship between industrial wastewater generation, abatement rate, discharge and economy in China

An empirical model was developed to investigate the long-debated relationship between industrial wastewater and economic development. Special attention was directly towards the connection between pollution characteristics (including generation, abatement, and discharge of industrial waste water) and rate of economic advancement. The relationship between industrial wastewater characteristics and gross domestic product (GDP) was examined using regression analysis by observed data in China from 1985 to 2006. The results show that the distribution of the observed data is in high accordance with that of the data calculated from the model. The relationships between GDP with industrial wastewater generation (IWWG), abatement rate (TR) and industrial wastewater discharge (IWWD), and demonstrate V-shaped, double connected inverse S-shaped, and reduced curves, respectively. IWWD conforms to the Environmental Kuznets Curve (EKC) at the situation of the rising left leg of the unobserved curve.
