摘要
基于1992—2006年我国民营科技企业时间序列数据,利用协整理论对民营科技企业科技创新绩效及其影响因素进行了实证分析,发现民营科技企业科技创新绩效分别对R&D资本存量、企业规模、科学家与工程师人数和体制的弹性系数依次为0.754、0.334、0.298和0.165,R&D资本存量对科技创新绩效的贡献最大。但是,只有企业规模才是影响民营科技企业科技创新绩效的直接原因,其它因素通过企业规模作为传导变量,形成规模经济来发挥作用,目前民营科技企业的科技创新存在规模收益递增状况。
Using the co-integration method,this paper discuses the dynamic equilibrium relationships between S＆T innovation performance and its influence factors on non-state-owned S＆T enterprises from 1992 to 2006. The result shows that there is a long-term equilibrium relationship between S＆T innovation performance and its influence factors,and the elasticity coefficients of R＆D capital reserve, enterprise scale,the quantity of scientist and engineer, system are 0.754, 0.334, 0.298 and 0.165, R＆D capital reserve is the leading factor. However,R＆D capital reserve,the quantity of scientist and engineer,system play a important role only by enterprise scale, at present,the returns to scale of S＆T innovation of non-state-owned S＆T enterprises is increasing.
