Research Programs: Raising Industrial and Firm Productivity

Determinants of the Productivity Gap among Firms in Japan

Project Leader/Sub-Leader


The productivity gap among firms within an industry, or firm heterogeneity, is becoming one of the most important questions in the fields of international economics, spatial economics, and industrial organization. It should be noted that the productivity growth of a country results from that of industries, which comes from that of firms. Therefore, to examine the source of productivity growth of the country, it is of the utmost importance to examine the productivity growth of firms.

This project examines the determinants of the productivity gap, using firm-level data. A number of studies have already examined the productivity growth of firms, using firm-level data in Japan. Building upon the previous studies, this project extends the focus to the market structure, employs a more sophisticated econometric methodology, and updates the analyses using the most recent version of the firm-level data.
