中文摘要：

运用超越对数生产函数随机前沿模型,在TFP分解下考察1990~2013年服务业内部结构演化及内在机制,并对新常态下服务业可持续发展动力进行分析。结果表明：我国服务业TFP增长核心逐步转变为技术进步,规模效率和配置效率改进整体低下。行业间规模效率改进异质性程度整体浮动较大,配置效率改进差异指数在2012~2013年快速上升,技术进步和技术效率改进整体平稳,TFP差异指数自2005年明显扩大,服务业渐进式改革及信息技术资源配置是其主导因素。

英文摘要：

Based on the decomposition of TFP on service sub-industry by Translog Stochastic Frontier model, the paper investigates the process of internal structural evolution and internal mechanism from 1990 to 2013, and analyzes the momentum of sustainable development of service industry. The result shows that, the dominant factor of service industry TFP growth gradually turns into technical progress, the overall levels of scale efficiency and allocation efficiency change are low. In sub-industry, the heterogeneity degree of scale efficiency change is considerably fluctuant, and the allocation efficiency change＇s difference index meets a rapid upward trend from 2012 to 2013. By contrast, the technical progress and technical efficiency change＇ heterogeneity degree are relatively stable, the TFP＇s difference index shows a further expansion since 2005. The possible reason of sub-industry＇ s heterogeneity evolution can be ascribed to the hetero- geneity effect of service industry＇ s gradual reform and information technology＇ s resource allocation.
