运用柯布-道格拉斯生产函数模型分析研发活动的成效

Research of Effectiveness of R&D Activities Based on Cobb-Douglas Production Function Model

本文采用柯布-道格拉斯生产函数模型,基于1995-2008年研发资金的投入和产出相关数据,对我国研发活动的成效进行了分析。总体而言,我国应该加大研发经费的支出。但如果我们更注重研发成果的质量,则研发资金的分配应该倾向于加大支持的强度;如果我们更注重研发成果的数量,则研发资金的分配应该倾向于支持更多的研发人员从事研发活动。同时,从长期来看,无论是以研发活动的质量还是数量为衡量标准,都应该增加对研发活动的投入,以实现研发活动的最佳规模。

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.
