Environmental pollution is the result of economic and population growth. Recently China hasbecome the second largest economies in the world with an average annual9%increase rate inGDP. However, China’s growth has long been relying on the increase of investment and materialinput. This extensive economic growth mode lead to a series of problems such as air qualitydeclining, river pollution deterioration, the ecology in coastal areas becoming more fragile andliving environment standard declining, which directly affect social economic welfare. China hasbeen increasingly focusing on the problem that how to achieve sustainable growth throughreducing environment pollution. Studying on the relationship between economic growth andenvironmental pollution has strategic value to the goal that guaranteeing economic growth whileachieving environmental protection.This paper focused on the relationship between the index of industrial wastewater emissionsin marine environmental pollutants and economic growth. Based on the China’s provincial paneldata from1992-2010, the existence and inflection point of Environmental Kuznets Curve inChina’s coastal areas were examined. The results show that:(1) there exists β convergence andclub convergence in economic growth of coastal areas. When it achieves its steady-state value,the convergence rate is0.5to0.8and the half-life-circle is about100years;(2)There exists anacademic inverted U-shaped relationship between the amount of industrial wastewaterdischarged into the sea in coastal areas and economic growth. The empirical examining ofenvironmental efficiency and economic growth conducted under the environmental constraintsalso demonstrated the theoretical mode. However, if the COD of industrial wastewaterdischarged into the sea in coastal areas is selected as the index, there exists an N-shaped curve. Itindicates that choosing different index have effects on the consistency of the conclusion. What’smore, the inflection point and maximum are different in different coastal areas. This indicatesthat pollutants emissions scale has certain relationship with economic stages in coastalareas.(3)Except Bohai Sea region, the COD emissions of industrial wastewater actuallydischarged into the sea in other coastal provinces are all smaller than their environmentalconstraints. It is found that the maximum of pollutants emissions don’t surpass environmentalconstraints coastal provinces, except Liaoning province and Hebei province.The innovations of this paper are as follows:(1)As for the theory, Inframarginal and NewClassical Economics analysis frame was used to build the model of negative externality ofenvironmental pollution, which mainly explains the relationship between the effect of negative externality of environmental pollution and maket capacity.(2)This paper reduced the restrictionon assumption of theory, introduced some assuming factors such as environmental constraintsand environmental input efficiency, and extensively analyzed the interrelation of environmentalpollution and economic growth.(3)Environmental constraint was introduced into EnvironmentalKuznets Curve theory, which made up for the deficiency in previous studies that neglectedenvironmental constraint when analyzing environmental pollution and economic growth. Thispaper also combines empirical analysis and empirical test.(4)This paper employed Varargs PanelData Model to conduct an empirical test of relationship between marine environmental pollutionin coastal areas and economic growth, which deal with the problem from two dimensions of timeand space.
