Based on the panel data of 17 subdivision industries of high-tech industry in China between 1999 and 2011, the paper calculates integrative TFP and R&D innovation TFP respectively and analyzed the causes of the differences between them by the method of Malmquist index of DEA model. The results show that the integrative TFP of each subdivision industry of high-tech industry mostly presents a trend of growth, and the growth mainly results from the joint improvement of both technical efficiency and technical progress. Moreover, the technical efficiency played a negative role on the growth of integrative TFP, the improvement and reduction of TFP has a certain difference between subdivision industries. The R&D innovation TFP of each subdivision industry of high-tech industry in China has been in low efficiency all the time, it is mainly due to appearing a negative growth in technical progress. The reasons to difference are analyzed. |
