Abstract: Based on the theory of Environmental Kuznets Curve, we used various models to test if the relationship between environmental wastes and gross domestic product in Inner Mongolia In order to provide suggestions for environmental policy and keep balance between environment protection and economic development, the authors studied the relationship between environment pollution and economic growth in Inner Mongolia. Based on the theory of Environmental Kuznets Curve (EKC), the authors used various models to test if the relationship between environmental wastes and gross domestic product in Inner Mongolia from 1986 to 2009 could fit the Environmental Kuznets Curve model. The authors discussed the relationship between environment quality and economic development of Inner Mongolia and estimated the trend of wastes discharge theoretically. The results showed that: 1) the production of volume of solid waste and industrial emissions in Inner Mongolia increased rapidly as per capita GDP increased, of which the relationship could fit the left part of the inverted ‘U-type’ EKC, the discharge of solid wastes had increased by 105.0832 million tons from 1986 to 2009 with the annual growth rate of 9.17% and the discharge of industrial emissions increased by 228.2836 million tons with the annual growth rate of 11.54%, while the emission of sulfur dioxide was surpassing the turning point of the curve, being in the decreasing phase of the inverted ‘U-type’ EKC. The discharge of liquid waste was in a slow growing phase accompanied by the increase of per capita GDP and the discharge of soot and dust displayed a general downward trend. Meanwhile, using the gray relative analysis method, the authors studied the internal association results, and the results showed the main factors which influenced environmental changes in Inner Mongolia included industrial structure, total gross domestic production, energy consumption in unit GDP and urbanization process. Based on our analysis, it presented a series of policy choices as guidelines for creating a win-win situation for both the economy and the environment.relationship between environment quality and economic development of Inner Mongolia and estimated the trend of wastes discharge theoretically. We concluded that: 1)the production of volume of solid waste and industrial emissions in Inner Mongolia increased rapidly as per capita GDP increased, of which the relationship could fit the left part of the inverted ‘U - type’ EKC， the discharge of solid wastes had increased by 105.0832 million tons from 1986 to 2009 with the annual growth rate of 9.17% and the discharge of industrial emissions increased by 228.2836 million tons with the annual growth rate of 11.54%， while the emission of sulfur dioxide was surpassing the turning point of the curve, being in the decreasing phase of the inverted ‘U - type’ EKC. The discharge of liquid waste was in a slow growing ohase accompanied by the economic development and the discharge of soot and dust displayed a general downward trend. Meanwhile, using the gray relative analysis method, we studied the internal association results showed that : the main factors which influenced environmental changes in Inner Mongolia included industrial structure, total gross domestic production, energy consumption in unit GDP and urbanization process. Based on our analysis we presented a series of policy choices as guidelines for creating a win-win situation for both the economy and the environment.
