Comprehensive Evaluation of Environmental Policies for Sustainable Development in Jiaxing

Recently, various environmental problems have been generated with the rapid economic development in China. The reason is that China currently over-emphasizes economic development beyond environmental issues; therefore, now it is important to enforce optimal environmental policies in order to achieve economic development as well as environmental improvement. In this study, we selected Jiaxing city as research area for the pollution problem has become more and more prominent with economic high growth, and we constructed environmental system model and social economic model to establish the scenarios. Through computer simulation, we can evaluate the efficiency of the comprehensive environmental policies from the aspects of both environmental preservation and social economic development. While the socioeconomic activities, such as production, finance and budget, are endogenous in the social-economic model, the environmental system model shows the water pollutants and the greenhouse gas reduction in the region. Based on the environmental and socio-economic system model above, the dynamic optimization simulation is accomplished. In view of the restriction on water pollutants, greenhouse gas emissions, and economic growth, the model simulation can provide optimal policies which can achieve the best economic and environmental improvement in Jiaxing City, China
