Outline of Final Research Achievements	We completed the new Japan Industrial Productivity (JIP) Database, which includes estimates of intangible assets and reflects changes in the 2008 SNA, and examined the determinants of service sector productivity in collaboration with overseas organizations such as the OECD and EU KLEMS. We found that the main causes of the recent stagnation of labor productivity in the service sector are the significant decline in human and physical capital accumulation, the underutilization of human resources, and the insufficient functioning of market selection. We also developed methods to measure the quality of output in healthcare, education, construction, housing, and other industries, and explored the causes of inefficiencies. Research outcomes: 85 conference presentations, 10 international research conferences, 186 academic papers and 21 books, including Fukao (2021), which summarizes the results. In addition, 7 databases were constructed and made available on the project website.

Academic Significance and Societal Importance of the Research Achievements	日本におけるサービス産業に関する統計の整備・改善はほとんど進んでおらず、他の先進国に後れをとっている。本研究では、日本を代表する生産性研究チームが統計部局等と連携し、海外との密接なネットワークも生かし、サービス産業の実質生産・生産性計測の抜本的改善と、生産と消費の同時性を考慮した新アプローチにより、サービス産業生産性の包括的研究を行い、世界の研究と経済政策に、大きな寄与が期待できる。
