Abstract:
Patent statistics have fascinated economists concerned about innovation for
a long time. However, fundamental questions remain as to whether or not
patent
statistics represent the real state of innovation. As Griliches pointed out,
substantial questions involve: What aspects of economic activities do patent
statistics actually capture? And, what would we like them to measure? He
pointed out that these statistics can be a mirage appearing to provide a
great number of objective and reliable proxies for innovation.

This paper aims to address some of these questions by making a comparative
evaluation of the representability of patent statistics in four levels of
the innovation process, using as examples research and development (R&D) in
Japan's printer and photovoltaic solar cell (PV) industries over the last
two decades. Furthermore, this research provides a new set of patent
statistics which could be considered a more reliable proxy for innovation.
