摘要
装备制造业在技术层面上决定了众多产业的竞争力和发展水平,而大企业又是装备制造业技术创新的主导力量。本文利用1995—2008年我国装备制造业14个3位数产业的面板数据,分别考察了技术创新投入、技术创新产出与企业规模之间的关系,主要结论为:(1)R&D经费支出、研发人员全时当量与企业规模之间表现为显著的倒U型关系;(2)新产品销售收入与企业规模之间呈现显著的倒U型关系,而以专利度量的创新产出与企业规模之间的关系并不明显;(3)市场结构对技术创新投入的影响并不明显,而市场结构与技术创新产出之间表现为显著的倒U型关系;(4)不论是对技术创新投入还是产出,国有企业比重都表现出显著的正效应。
Equipment manufacturing determines the competitiveness and levels of the developing of many industries on the technical level, and the large companies are the dominant forces in equipment manufacturing technological innovation. Based on the 14 3-digit industries＇ panel data of equipment manufacturing in China from 1995 to 2008, this paper investigates the relationships between technological innovation inputs, innovation output and finn size. The main conclusions are： （1） The relationship between R＆D expenditures, R＆D full-time equivalent and firm size are significantly inverted U-shaped; （2） The relationship between new product sales and firm size is significantly inverted U-shaped, while the relationship between the output of innovation measured by patent and firm size is not obvious; （3） The impact of market structure influences on the technological innovation input is not obvious, and the relationship between market structure and technological innovation output is significantly inverted U-shaped; （4） The proportion of state-owned enterprises have shown a significant positive effect on the technology innovation input and output.
