Trends in R&D, innovation and productivity in Sweden 1985-2002
() and Astrid Kander
Abstract: We use a new, comprehensive database covering Swedish
industry and service firms 1985-2002, to examine trends in the ratio
between patenting and R&D (PR-ratio). There is a fall in PR-ratios in the
long run (1985-2002) on the aggregate level and for all sectors. In general
low-tech sectors perform better in terms of PR-ratios than high-tech
sectors. A fall in the PR-ratio could be offset by increasing patent
quality. We use two indicators of quality in this paper: forward citations
and family size. The quality-adjusted PR-ratios also fall in the long run,
but unlike the raw PR-ratio that falls drastically after 1997, the fall
only takes place in the first half of the period (1985-1994), and then
levels out. There is thus strong correlation between the Swedish economic
growth performance and the quality-adjusted PR-ratios. The trend in the
quality adjusted PR-ratio is mainly driven by the Paper, pulp and paper
products industry together with R&D in science, engineering and medicine.
We find high correlation between quality-adjusted-patents and R&D at the
sector level, but not between quality-adjusted-patents and growth in value
added or labour productivity.
