【 摘 要 】

Analyze the input and output status of various environmental pollution control projects in Qingdao from 2007 to 2015, and then use the super-efficiency DEA and ML index methods to calculate the comprehensive efficiency. The results show that the comprehensive efficiency of environmental pollution control is increasing year by year, but Compared with advanced cities, there is still a big gap; scale efficiency has not been optimal, and scale returns are diminishing; the efficiency of industrial waste gas, industrial waste water, sewage treatment and greening is relatively low, and the efficiency of waste and waste treatment is relatively high. The input or output scale of pollution control projects should be adjusted, the concentration of treatment should be improved, and the system improvement, technology and management level should be promoted.
