Purpose of the workshop
This international workshop on "Economics of Interfirm Networks" presents empirical research based on a massive transaction relationship database of approximately 400,000 Japanese firms over multiple years. It focuses on the role of interfirm networks in four different fields of economics: (1) macroeconomic fluctuations, (2) economic geography, (3) the economics of productivity and innovation, and (4) firm-bank relationships. We believe that the workshop will provide an excellent opportunity to gain a more integrated understanding of the role of networks in the economy.
The workshop is organized as part of the research project on "The Design of Interfirm Networks to Achieve Sustainable Economic Growth" at Hitotsubashi University and is joint-hosted with the Research Institute of Economy, Trade and Industry (RIETI). The project seeks to gain insights into the role of interfim and financial networks in achieving sustainable growth, making use of a massive firm-level dataset constructed in collaboration with Japan's largest credit research company (Teikoku Data Bank Incorporated). The dataset covers a substantial portion of Japanese firms and contains information on their transaction partners, shareholders, financial institutions, and other attributes, including location and performance. The initial research results of the project are now becoming available, and the aim of the workshop is to disseminate the findings obtained hitherto.
