The Yang He reservoir is an important reservoir used for drinking and agricultural water of Qin Huang Dao in He Bei China. Wastewater from starch processing by a starch noodle factory west of Yang He has been an important reason for pollution since about 1998. Other pollutants include agricultural and domestic drainage. Water quality deterioration in the reservoir has had a major influence on the water supply of the city. The purpose of this study was to investigate the management of the environmental conditions of the reservoir and suggest ways to improve the environment by considering economic development, finance and the water quality of the Yang He reservoir. An environmental-social economic model was formulated and a simulation of the model performed to determine ways for improvement of the water quality and promote sustainable development of the Yang He reservoir. In promoting the environmental policy, the water pollution levels in the region were set from 0% reduction to 6% reduction for the study. A feasible solution was simulated by considering the pollutant reduction, GRP and the total budget. As a result, the best adjustment was with the restriction value set at 6% reduction, and the GRP increased 14.3% during the 10th period. In addition, T-N, T-P and T-COD decreased 9.82%, 11.68% and 15.28%, respectively. This method appears to be applicable to developing countries such as China.JEL Classification: Q53, Q58
