The purpose of this project is to update and refine our Regional-Level Japan Industrial Productivity Database (R-JIP) and to carry out some related analyses using the database. Since many Japanese rural regions are predicted to face severe decline in population and rapid aging, it is vital that they objectively examine their position within national production networks and design coherent policy to remedy the situation. To extend the database beyond 2012, construction of the database must be updated in adherence to SNA2008 and new industrial classifications. In this project we examine the estimation method to adapt to new criteria and new data series from 2006 to 2015. We also provide inter-regional IO tables divided by prefectures. Since the 2005 inter-prefectural IO table is nearly complete, we conduct analysis of industrial linkages among prefectures. We carry out analysis of regional productivity differences taking into account land input as well as other factors that may influence them. In performing these analyses we can shed new light on regional productivity differences.
