Innovation and Productivity Across Four European Countries
利用企业调查数据，比较法国、德国、西班牙和英国四国中创新对生产率的作用，发现驱动创新和生产率的系统总体相似，但创新活动差异与生产率变化有关。
This paper compares the role innovation plays in productivity across four European countries, France, Germany, Spain, and the UK, using firm-level data from the internationally harmonized Community Innovation Surveys (CIS3). Despite a considerable number of national firm-level studies analysing this relationship, cross-country comparisons using micro data are still rare. We apply a structural model that describes the link between R&D expenditure, innovation output, and productivity (CDM model). Our econometric results suggest that overall the systems driving innovation and productivity are remarkably similar across these four countries, although we also find interesting differences, particularly in the variation in productivity that is associated with more or less innovative activities.
