基于四阶段DEA和Bootstrap—DEA模型对中国城市公共支出效率进行比较分析，结果表明：传统DEA方法测算的城市公共支出效率值被明显低估；城市产业结构、政府对城市环保的重视程度对中国城市公共支出效率具有显著的影响；基于绿色发展的中国城市公共支出效率差异明显，东部城市的综合效率明显好于中部和西部，而西部城市的规模效率较好，中部城市作为夹心层，各项效率均较低。

英文摘要：

A comparative analysis is made on the urban public expenditure efficiency in China based on the four - stage DEA and Bootstrap - DEA model, and the results show that traditional DEA method significantly underestimated the value of urban public expenditure efficiency; urban industrial structure, and the degree of government concern on urban environmental protection has significant influence on China＇s urban public expenditure efficiency; public expenditure efficiency based on green development in different cities is clearly different, with the comprehensive efficien- cy of eastern cities better than those in the central and western regions. However, the scale effi-ciency in western cities is comparatively better. As a sandwich layer, the efficiency values of the central region are relatively lower.
