中国服务业技术效率在时间和空间上不断发生变化，并导致区域之间的差异。本文运用随机前沿分析方法和马尔可夫转换模型测度分析了30余年来（1978～2012）各省区服务业技术效率值，从时间和空间两个角度定量化研究了其演变特征与规律。结果表明：（1）服务业的技术效率在时间和空间两个维度变化，服务业技术效率整体有很大提高。当前东部地区服务业技术效率主要居于较高水平，内部服务业技术效率差异较大；中部地区主要居于较高水平；西部地区内部差异较小，都居于较高水平。（2）各地区服务业技术效率水平越低，变化的幅度和速度越大；水平越高，变化的幅度和速度越小。%The technical efficiency of Chinese service industry continuously changes in time and space . And this lead to regional differences . In this paper , using the stochastic frontier analysis method and Markov transformation model to measure and analyze the tech-nical efficiency of service industry of more than 30 years (1978-2012) in different provinces , and to study quantitatively the characteris-tics and laws of evolution of this from two angles of time and space . The results show that :the first , the technical efficiency of service in-dustry in two dimensions of time and space changes . And it is great to improve the technical efficiency of service industry as a whole . The efficiency of service industry in the eastern region is mainly at the higher level , and regional internal difference of technical efficiency is big . And internal difference of service industry in the central region is at a higher level . The internal differences in the western region is at a higher level . Second , the lower level of technical efficiency of regional service industry , the greater magnitude speed of change . The higher the level is the scale and speed of change is smaller .
