Abstract This paper empirically analyzes the correlation between TFPG(Total Factor Productivity Growth)of manufacturing firms in Japan and their annual R&D(Research and Development)intensity. By analyzing firm's annual final account data from 2004th to 2009th , multiple regression analysis suggests that R&D investment played a role in Japanese manufacturing industries' firm TFP growing, but it takes times to work. And R&D investment intensity exerts different effect for different types of industries before Economic Crisis, but after Economic Crisis, this trend disappeared.
