Yang Qing-fen

Abstract

This paper evaluates the technical efficiency of high-tech industry by using DEA analysis method.The empirical results show that the technical efficiency of high-tech industry is generally low at current stage,which is mainly caused by the lower pure technical efficiency.The increasing trend of scale returns appears on the whole in China at present.By using projection analysis,the region resources investment can be adjusted,and then DEA efficiency is achieved.
