Persistent heterogeneity of R&D intensities within sectors: Evidence and policy implications
Research Policy(2019)
摘要
•Do firms in the same sector converge towards the same R&D intensities?.•We use EU Industrial R&D Investment Scoreboard data for 2000–2015.•There is persistent heterogeneity in R&D intensities among firms in the same sector.•Variation in R&D intensities does not decrease over time, i.e. no sigma-convergence.•Firms with low R&D intensity catch up with the industry leaders, i.e. evidence of beta-convergence.
