| Outline of Final Research Achievements |
This research project investigates how an expansion in a service sector affects economic growth. The results are summarized as follows. First, if services are used for intermediate inputs as well as final consumption, an expansion in the services sector decreases the growth rate of the economy in the long run. Second, if the government gathers taxes to finance the public services that increases the total factor productivity of the economy, the economy shows various dynamics depending on the flexibility of the wage rate. On the one hand, if the wage is rigid, then the economy experiences cyclical fluctuations. On the other hand, if the wage is flexible, then the economy stably converges to its steady.

現在，すべての先進国において経済のサービス化が進行している．サービス化が進行が経済成長等にどのような影響を与えるかについては様々な議論があるが，サービス化の行く末を知るためには，厳密なモデル分析が必要となる．本研究では，厳密なモデル分析を用いて，サービス化が経済に与える影響を分析した．サービスの性質を十分に考慮したモデルを構築し，その分析をから得られた結果は，サービス化の進行は必然的に経済成長を鈍化させるというものである．この帰結には，サービス部門の生産性成長率が低いという前提が大きく影響している．したがって，経済成長の鍵を握っているのは，サービス部門の生産性成長率である．
