چکیده
The computer industry plays an important role in promoting the development of national economy and national comprehensive power of China. As an important evaluation indicator, the R&D efficiency of computer industry becomes one of the most important research fields currently. According to the shortages of traditional C2R model of DEA, this paper constructs an improved DEA model for measuring the R&D efficiency of computer industry and does an empirical research on R&D efficiency of computer industry in different regions. This research shows that: the improved DEA model overcomes the shortages of traditional C2R model and it is able to reflect the difference of R&D efficiency between different regions more effectively; Compared with efficiency frontier, the R&D efficiency of Chinese computer industry has potentials to improve; The R&D efficiency of Chinese computer industry is influenced by various factors, such as government support capacity, market structure and enterprise scale; Improve the environment of R&D activities is more effectively than increase the input of R&D resources in improving the R&D efficiency of Chinese computer industry.
