Study on the innovation efficiency of China's high-tech industry considering the enterprise nature

摘要

This paper applies the DEA model to measure the innovation efficiency of the regional high-tech industry, domestic, Hong Kong, Macao and Taiwan and foreign-invested enterprises in China between 2008 and 2014. The results show that: (i) from the whole, if the differences in enterprise nature is not considered, the average innovation efficiency of China's high-tech industry is 0.748, and the pure technical efficiency and scale efficiency have some space to improve. The industry efficiencies in central and western provinces are low. (ii) The average efficiency of China's domestic, Hong Kong, Macao and Taiwan and foreign-invested enterprises are 0.476, 0.529 and 0.525 respectively, which are lower than traditional DEA efficiency significantly, the efficiency of domestic enterprises was the lowest, and it showed a slight increase during the examination period. There are some differences in the root causes of efficiency loss in each province. For example, domestic enterprises' innovation efficiency in Beijing is low, et al.
