Knowledge stocks, knowledge flows and innovation: : Evidence from matched patents and innovation panel data
Research Policy(2015)
摘要
•Based on an econometric analysis of a matched dataset comprising innovation panel data and plants’ patent histories.•Existing knowledge stocks – measured by patents – have weak negative rather than positive impacts on firms’ innovation outputs, reflecting potential core-rigidities or negative path dependencies.•Knowledge flows derived from R&D investment and external search dominate the effect of existing knowledge stocks on innovation performance.•Results emphasize the importance of firms’ current knowledge search strategies for innovation.•Results re-emphasize the potential issues which arise when using patents as a measure of innovation.
