Innovation has become a key factor for economic growth, but how does the process take
place at the level of individual firms? This book presents the main results of the
OECD Innovation Microdata Project -- the first large-scale effort to exploit firm-level
data from innovation surveys across 20 countries in an internationally harmonised
way, with a view to addressing common analytical questions. Through the use of common
indicators and econometric modeling, this analytical report presents a broad overview
of how firms innovate in different countries, highlights some of the limitations of
current innovation surveys, and identifies directions for future research.
