Abstract

本論文では,我が国における民間部門のプロダクト・イノベーションの特性を概観した後,その特性を捉える動学的な推定モデルを紹介する.既存の調査結果のうち,イノベーション活動に伴う波及効果が存在することを示す結果をいくつか取り上げ,政策的な介入,とりわけ補助金付与の持つ役割に着目をし,その政策がイノベーション活動に与える影響を定量化するための新しいフレームワークを提示する.

This paper provides an overview on features of product innovation performed by the Japanese private sector, and proposes a dynamic estimation model to capture such features. Recent survey data imply that Japanese private firms strategically engage in their innovative activities. They also indicate the presence of spillovers in the innovative activities, which may well justify the policy intervention on innovation activities in the private sector. We particularly focus on the role of public subsidies, and propose a new analytical framework to quantify the effect of the policy on innovative activities. The suggested model incorporates a Markov perfect equilibrium with a particular attention to firms' strategic interactions and spillovers in their product innovation. The agenda for future research is also discussed.
