摘　　要：本文利用超越对数生产函数的随机前沿模型,基于经过普查修订的历史数据,对改革开放以来中国服务业TFP增长率进行详细分解,发现其效率演进过程存在阶段性特征,1992年为分界点,其中技术效率改进是主导TFP变化的核心因素,而个体经济粗放经营所导致的规模效率恶化是阻碍TFP增长的消极因素;服务业技术进步及其区域差距分别经历了"U"型和"倒U"型的演变过程;配置效率的持续改进出现在1992年之后。Based on the revised historical data according to the first economic census, this paper uses the stochastic frontier model of translog production function to decompose the growth of TFP of service industry since China＇s reform and opening up, and finds finding the feature of stage in efficiency evolution process with 1992 being the turning point the composition of TFP growth in the service sec- tor, technical efficiency change is the core elements leading to the change of TFP, scale inefficiency led by extensive operasrion is the negative factor hampering the growth of TFP. The technological progress and its regional disparities were respectively experiencing a ＂U＂ -type and an inverted ＂U＂ -type process of evolution.
