摘　　要： 提供一种基于知识积累的解释,将知识积累区分为两种方式:“干中学”和“R&D学习”,并将其引入总产出方程。通过对模型的分析,认为较低的知识弹性系数、较低的“R&D学习”效率、较大的物质和劳动物理形态产出弹性系数和“干中学”学习效率,是导致我国科技投入强度偏低的重要原因。并对我国产出较低的知识弹性系数、较低的“R&D学习”效率的原因给出了自己的思考。 In this paper, the authors try to provide an explanation based on knowledge accumulation which is classified into 'learning by doing and learning by R&D and included into the aggregate output equation. By analyzing the model, the authors conclude that small coefficient of knowledge elasticity, low efficiency of learning by R&D , large coefficient of material-and-labor-physics-formed output elasticity, and high efficiency of learning by doing are the important factors which lead to small R&D expenditure intensity. We also put forward some explanations to the reason for small coefficient of knowledge elasticity and low study efficiency of R&D in China.
