Abstract: Based on financial input and output data of research and development (R&D) from years 1995 to 2008, we analyze the effectiveness of R&D activities using the Cobb - Douglas production function model in this paper. Some interesting conclusions have been obtained as: Overall, China should increase R&D expenditures. However, the allocation of R&D funding should be inclined to increase the strength of support if we pay more attention to the quality of our R&D results. The allocation of R&D funding should be inclined to support more R&D personnel to do R&D activities if we pay more attention to the quantity of R&D results. Meanwhile, in the long term, R&D expenditure should be increased in order to achieve optimal scale for R&D activities whether the quality or quantity is taken as the measure for R&D activities.
