Empirical Analysis of Total Factor Productivity of R&D in High-tech Industry——Based on Malmquist Index Method of DEA Model

By using panel data related to high-tech industry from 2000-2009,we build DEA model based on Malmquist productivity index and its decomposition index,which contains technical progress efficiency and comprehensive efficiency changes index,and therefore make empirical analysis on the development of productivity of RD in high-tech industry.The results show that the development of high-tech industry is not balanced in all industries,the development of productivity in some parts of industries are volatile,while the other parts are relatively stable.Overall,all the index of high-tech industry productivity show very stable performance,we also find that from 2000 to 2004 the main motive force which promotes the development of total factor productivity is the improvement of comprehensive management level,and from 2005 to 2009 the main motive force is technical progress.The main supporting force of the average growth rate of total factor productivity is derived from the technical progress efficiency.
