摘　　要：运用2009年海淀区R&D资源清查中671家企业的微观数据,考察了企业规模差异下R&D投入对生产率作用的差别,得到的主要结论如下:R&D投入对大、中、小型企业的生产率都有积极影响,R&D产出弹性按照大、中、小型企业依次递增,并且中小型企业的R&D产出弹性远远高于大型企业。同时,利用全部样本企业的分析结果也显示R&D产出弹性与企业规模存在负向相关关系,这与现有研究结果不同。Using microcosmic data of 671 firms in Haidian District from R＆D resource census in 2009, this paper examines the effect of R＆D input on firm＇s productivity in the case of different firm size, and the main conclusions are as following： R＆D input has positive effect on the productivity of small firms, medium firms and large firms. The R＆D capital output elasticity increases by firm size, and R＆D capital output elasticity of small and medium firms is remarkably larger than the corresponding elasticity of large firms. Meanwhile, we also find that there exists negative relationship between firm size and R＆D capital output elasticity based on the analysis of full sample, which is different from prior studies.
