Abstract
Given the rapid development of the industrial economy, the environmental problems caused by water resource pollution have increased in severity. Thus, the optimal use of various natural resources and the reduction of water environmental pollution are important to promote the healthy development of the social economy and the environment. In this paper, the 2001-2013 time series data of discharged volumes of industrial wastewater, industrial chemical oxygen demand, and GDP are employed to analyse the relationship between the water environmental pollution and economic growth of Beijing, Tianjin and Zhengzhou. First, two models are established for the F test and T test on the relationship between GDP per capita and water pollutant discharge. A complete decomposition model is then adopted to analyse the effects of economic scale, industrial structure, and technological progress on water environmental pollution. Investigation results indicate that the relationships between the industrial wastewater discharge and economic growth of Beijing, Tianjin and Zhengzhou show reverse N-shaped curves instead of reverse U-shaped curves. At present, higher economic growth leads to more industrial water pollution. Economic scale and technological progress are the major influencing factors of water pollutant discharge. Therefore, the overall regional water environmental quality can be substantially improved only by enhancing the cooperation between Beijing, Tianjin and Zhengzhou to improve the capacity and efficiency of regional pollution control.
