高技术产业R&D全要素生产率变动分析-基于DEA模型的Malmquist指数方法

运用2000年至2009年高技术产业相关面板数据,构建了基于DEA模型的Malmquist生产率指数及其分解指数即技术进步指数和综合效率改善指数,并由此对高技术产业R&D的生产率发展状况进行实证分析.结果发现:高技术产业的各行业发展并不均衡,部分行业生产率发展波动较大.而另一部分则相对稳定.整体来看,高技术产业的生产率各指数表现较稳定,同时发现2000- 2004年推动全要素生产率发展的主要动力是综合管理水平的提高,而2005-2009年的主要动力是技术进步.从全要素生产率的平均增长率来看,主要支撑动力是来源于技术进步指数.

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 R&D 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.
