中文摘要：

将投入产出表与DEA综合使用，构建了基于投入产出表的DEA模型，拓宽了数据包络分析应用范围；针对江西经济发展现状和产业特性，基于投入产出分析技术界定生产性服务业范围：以2007年江西省投入产出表为DEA模型数据基础，构造C2R模型评价生产性服务业各部门效率：最后提出了相应的调整方案。结果表明：江西生产性服务业24个部门中仅4个部门达到技术和规模有效，其余20个部门为非DEA有效，均存在不同程度冗余。

英文摘要：

The method that combined with input- output table and DEA opens up new uses for the input-output table, broadens the scope of application of DEA; Based on the current economic status and industrial characteristics in Jiangxi, this paper defined Jiangxi producer services in the quantitative view, made input-output table in Jiangxi as a data base for DEA, evaluated efficiency of producer services by constructing C2R model, and made recommendations The results show that： only four departments of Jiangxi producer services achieve effective technology and scale, the remaining 20 departments are non - DEA and have input redundancy.
