An Empirical Analysis on Technical Efficiency of China Hi-Tech Industry ——A Nonparametric Malmquist Index Approach

Ye Zhen

Abstract

Based on panel data of industry from 1995 to 2005 and theory of efficiency, this paper analyzes the technical efficiency and TFP change of hi-tech industry by using the nonparametric Malmquist index approach. The results show: it is the improvement of technical progress rather than technical efficiency promote TFP growth rate of hi-tech industry, in addition, TFP and technological change are slow gradually with time varying, and technical efficiency, TFP and technological change are exist obvious differences between every industriy.
