The Evaluation of Beijing Sustainable Development Based on DEA Model
基于DEA 方法的北京可持续发展能力评价

Whether the development of Beijing at high speed is sustainable or not is a pivotal problem,so we use the DEA(data envelopment analysis) model to evaluate the sustainability of Beijing based on the input output matrix and the index of sustainable development.We know Beijing has the potential of sustainable development,but we need to improve the utility of manpower,material,and resource,and we must pay attention to the scale benefit,the technology availability and the environment protection,and it is necessary to advance the recycling economy for Beijing's sustainable development.
