Empirical Research on Technical Efficiency of High-tech Industry Based on Factor Analysis and Data Envelopment Analysis——Taking Beijing as an Example

Problems of conversion efficiency of high investment and sources of total factor productivity are urgent for Beijing high- tech industry's development. Based on factor analysis and data envelopment analysis,technology efficiency of Beijing high- tech industry from 1996 to 2010 is empirically studied; index systems are established through methods of literature research and factor analysis firstly; technology efficiency is measured based on data envelopment analysis on Malmquist productivity index and C2R model respectively. The results show that the combination method of factor analysis and data envelopment analysis is feasible,and the technical efficiency of Beijing has reached efficiency since 1999 in the sample of nationwide high- tech industry and increased by an average of 0. 2%,and main source of total factor productivity is technology progress. In addition,the cause of inefficiency of eastern region is also analyzed,and some proposals are put forward to upgrade technology efficiency of Beijing high- tech industry.
