摘要
基于构建的非线性R&D活动投入产出弹性模型,以2007年《中国工业企业数据库》中35 369个企业样本的截面数据为研究对象,分析了企业创新能力与企业规模之间的关系特征。研究发现:在不同的企业规模定义下,R&D活动产出效率与企业规模之间呈现不同的关系,这一结论与已有研究不同。将企业分为高技术企业和中低技术企业之后,发现技术水平因素并不影响R&D活动产出效率与企业规模之间的关系。
By building a nonlinear R＆D activities input-output elasticity model, based on the sample of 35369 enterprises in the Chinese industrial enterprises database in 2007 for the study, this paper analyzed the relationship between the characteristics of the innovation capability of enterprises and enterprise scale. The empirical results show that, by different definition of firm size, R＆D activities show a different relationship between the output efficiency with the scale, and this conclusion is different from the existing research. Further divided into the high-tech sector and the low-skilled sector, the technical level factors do not affect the relationship between the output efficiency of R＆D activities and the scale.
