title = "Measuring the intensity of knowledge flow with patent statistics",
abstract = "Our study is based on the patent data of 224 firms in the computer, chemical, and electronic and electrical industries worldwide. We find that on average 19.3% of the knowledge spillover is generated within the industries, with the rest stemming from other industries. Also, there is a significant positive relationship between technological overlap between firms and internal knowledge flow in an industry.",
