创新资金使用结构对创新产出的影响:基于中国区域工业企业的实证研究

Research on the Impact of Innovative Capital Use Structure on Innovation Output:Empirical Study of China's Regional Industrial Enterprises

基于创新价值链理论,将创新产出分为中间产出和最终产出,以2011-2017年我国内地28省份工业企业为研究对象,在控制创新资金规模不变的前提下,运用随机效应模型和门槛回归模型研究创新资金使用结构对创新产出的影响机理。结果发现:自主研发资金比例与专利申请量、新产品销售收入显著正相关,技术引进和技术购买资金比例对专利申请量影响不显著,技术引进和技术购买资金比例与新产品销售收入显著正相关,技术改造资金比例与专利申请量、新产品销售收入负相关;自主研发资金比例在专利申请量、新产品销售收入之间存在显著单一门槛效应,当自主研发资金比例跨越门槛值后,其对专利申请量的促进作用减小,而对新产品销售收入的促进作用增大。该结论从创新要素结构视角拓展区域创新理论,对提升区域工业企业创新产出水平具有一定借鉴作用。

Based on the theory of innovation value chain,innovation output is divided into intermediate output and final output.The industrial enterprises in 28 provinces of China from 2011 to 2017 are taken as the research objects,this paper explore the impact of innovation capital use structure on innovation output by using the random effect model and threshold regression model on the premise that the scale of innovation capital remains unchanged.The results of this research show that the proportion of independent research and development funds is significantly positively correlated with the number of patent applications and new product sales revenue.The proportion of technology import funds and technology purchase funds has no significant influence on the number of patent applications.The proportion of technology introduction funds and technology purchase funds is significantly positively correlated with the sales revenue of new products.The proportion of technology transformation funds is negatively correlated with the number of patent applications and the sales revenue of new products.There is a significant single threshold effect between the proportion of independent R&D funds and the number of patent applications and the sales revenue of new products.After the proportion of independent research and development funds exceeds the threshold value,its promoting effect on the number of patent applications decreases,and its promoting effect on the sales revenue of new products increases.The conclusion expands regional innovation theory from the perspective of innovation factor structure,and has certain practical significance to improve the innovation output level of regional industrial enterprises.
