Outline of Final Research Achievements

This study considers the effects of R & D on upstream and downstream companies in the equilibrium of oligopolistic firms, and finds that R & D affects the industrial structure.
In addition, we find that prefectural R & D subsidies are effective in improving corporate productivity, and those effects are enhanced by other government subsidies, and have spillover effects on the economic activities of other prefectures.
Furthermore, in this study, we investigated the signaling effect of the wine brand by conducting an experiment in which subjects were asked to taste a random combination of wine and label and a combination of wine and label that was actually sold.

Academic Significance and Societal Importance of the Research Achievements

近年、知的財産はパテントだけではなく、消費者情報、商標、ブランド等も含まれる概念である。よって、本研究でも知的財産に関して多様な分析を行い、その特徴を研究した。理論的結果から、知的財産が産業構造をより寡占的にさせる懸念が指摘され、また政府の研究促進政策が正の効果を持つことなど、政策的インプリケーションが得られた。また、ラベルと中身の組み合わせという新しいブランドの概念も提唱され、有名ブランドが中身の高評価につながらない興味深い結果が得られた。
