知识来源和创新联系的地理分布对创新绩效的影响研究

The Impact of Geographical Distributions of External Knowledge Sources and Innovation Linkages on Innovation Performance

文章基于空间分布的视角,以北京地区汽车零部件、软件和生物产业的456家企业为例,研究了外部知识来源和创新联系的地理分布对不同水平创新绩效的影响以及内部研发投资的调节作用。结果表明,企业国际化的知识来源与突破性创新之间存在倒U形关系。企业进行研发采购时倾向于选择地理范围较远的伙伴,而且国际研发采购确实能增加企业产生突破性创新的可能性;企业开展研发合作时倾向于选择地理范围较近的伙伴,但无论与何种地理分布的伙伴合作均未能增加企业产生突破性创新的可能性。企业的内部研发投资会抑制国际研发采购、国际研发合作和区域内研发合作对突破性创新的影响。

From the angle of spatial distribution, this paper takes the sample of 456 firms referring to automotive components, software and biotech industries in Beijing, and studies the impacts of geographical distributions of external knowledge sources and innovation linkages on innovation performance, as well as the moderating effect of internal R＆D investment. The empirical results show that there is an inverted U-shape relation between international knowledge sources and the probability of radical innovation. When being engaged in R＆D outsourcing, firms prefer to select partners with long distances, and international R＆D outsoureing really increases the probability of radical innovation; when being engaged in R＆D collaboration, firms prefer to select partners with near distances. However, R＆D collaboration with partners with all geographical distributions could not increase the probability of radical innovation. Internal R＆D investment keeps a curb on the impacts of international R＆D outsourcing, international R＆D collaboration and regional R＆D collaboration on radical innovation.
