| 摘 要： | 以70家制造业上市公司为研究样本,对公司规模与R&D投入的关系进行了实证检验。研究结果表明,我国制造业上市公司R&D费用强度和R&D人员强度与企业规模都显著负相关,而R&D投入绝对额与企业规模显著正相关;我国制造业上市公司R&D费用强度平均达到了国际上公认的维持生存的水平(2%),但分布不均,低投入状况与高投入状况并存;但从R&D人员投入来看比较理想,大多数公司的R&D人员强度达到了发达国家10%的水平。 ?

| Abstract: | Based on 70 manufacturing firms data,this paper investigates the relationship between firm size and R&D input.The results indicate that R&D expenditure intensity and R&D employee intensity with firm size present significantly negative correlation and the amount of R&D expenditure with firm size presents significantly positive correlation.The results also suggest that the average R&D expenditure intensity of manufacturing firms in China achieves survival level(2%),but the distribution of it is not uniformity... |
