Overview
How to raise Japan's labor productivity and potential growth rate in order to ensure sustained wage growth and maintain the social security system under a declining and aging population and how to best utilize new technologies, such as AI and robots, are urgent policy issues. Meanwhile, the deceleration of the Chinese economy against the backdrop of an aging population and the U.S.-China decoupling, as well as changes in the structure of global value chains, mean that there is an even greater need to understand changes in productivity and the division of labor in East Asia.
Against this background, the purpose of this project is to investigate these issues by updating and expanding the Japan Industrial Productivity (JIP) Database, the Regional-level Japan Industrial Productivity (R-JIP) Database, and the Asian Industrial Productivity (AIP) Database, which capture changes in industry, trade, and regional structure as well as the sources of productivity growth in Japan and East Asian countries by industry, and by conducting empirical research using microdata from government statistics.
