Nobu Yamashita is part of a large project examining the dynamics of knowledge diffusions and the innovation performance of Japanese firms.
The project is led by Dr. Isamu Yamauchi of the Research Institute of Economy, Trade and Industry (RIETI) in Japan – a semi-government research institution in Tokyo. Nobu is examining the innovation performance of Japanese firms as a response to intensified import competition from China.
He is using a new firm-level data set, combining firm-accounting data from the Basic Survey of Business Activities conducted by the Ministry of Economy, Trade and Industry (METI) and the Survey on Intellectual Property Related Activities (SIPA) implemented by the Japan Patent Office. The data covers roughly 5,600 firms annually for the period of 1991-2013..
