Abstract
The aim of this paper is to analyze the impact of the Unfair Competition Prevention Law on the Japanese innovation activity and, in particular, on the R&D expenditure-patent dynamic. Considering the patent statistics as a good proxy of the innovation processes, we outline the historical series of the patents granted in the manufacturing Japanese industries (the sectors we are interested in examining). We proceed by studying the effects of the R&D expenditures on the patent trend and we try to define the optimal lag between the funding and its productivity effect. Subsequently, we inquire on the impact that the trade secret law might have had on the model. A Chow breaking test is applied in order to see if there was a significant difference in the estimated equation after the promulgation date.
