摘要

With the data collected from 168 enterprises in Hubei province, innovation efficiency is evaluated and analyzed in terms of efficiency, effectiveness, returns to scale, and projection analysis by using DEA method. The results indicate that only15.48% of the enterprises operate on the best-practice frontier and there exist significant discrepancy between different types of enterprises in terms of innovation efficiency. Increasing returns to scale are found among 46.43% of the enterprises and decreasing returns to scale are found among 35.12% of the enterprises. Scale efficiency is the main factor which leads to low innovation efficiency; and the insufficient input of R&D personnel and the inappropriate allocation between R&D Personnel and R&D expenditure are the fundamental reasons leading enterprises non DEA effective. The empirical results indicate that there is much room for enterprises to improve its innovation efficiency, and specific adjustments are proposed for each type of enterprises on the basis of empirical analysis.
