Under the framework of the coordinated strategy, the research on the efficiency of industrial and ecological expenditures is gradually deepened. This paper uses DEA-Malmquist model to calculate the expenditure and effect of industrial optimization and ecological development policies in 16 districts of Beijing from 2010 to 2020. It focuses on the changes of overall efficiency and decomposition efficiency. Results show that: First, the overall efficiency of expenditure shows a fluctuating trend, the effectiveness of expenditure efficiency level varies greatly in different regions. The efficiency of the upper central city is low, while that of the marginal city is high. Second, technological progress and scale efficiency are the main factors that cause the overall efficiency to decrease. The pure technical efficiency is the key to promote the industrial structure and urban ecological optimization expenditure efficiency. Third, the change of technological progress efficiency is related to the cyclical change of technology. The characteristics of effect have changed from a large change range and a short change time in the early stage to a small change range and a long change time.
