Outline of Final Research Achievements

The purpose of this study is to clarify the process and process of innovation generation in the construction industry. By measuring and organizing publicly available data, such as bidding data and management screening data, the characteristics of innovative firms were verified based on the data, and the factors necessary for promoting innovation were clarified. In recent years, productivity improvement has become a major issue in the construction industry, and the creation of innovation is the key to achieving this goal. Innovation research has made significant progress in industrial organization theory, both theoretically and empirically, and we considered applying this research to the construction industry to address the necessary issues. The results verify that an increase in the size of demand has a significant positive effect on the generation of innovative firms, especially the total demand and the number of orders.

Academic Significance and Societal Importance of the Research Achievements

本研究は、日本の公共調達データを用いて、イノベーションが需要と強く有意に関連し、入札総額と入札件数で説明できることを、固定効果モデルで実証した。第一に、個々の企業の行動から一定の要因を特定することができた。これまで、エビデンスに基づくイノベーションに着目した建設マネジメントの研究はほとんど行われていない。第二に、様々なアプローチの利点と弱点を理解し、現象を統合的に理解し、より高いレベルで統合するために、イノベーション研究における新しいモデリングを用いた実証研究を行った。実際の集計データを活用し、整理する道筋を作った。これにより、イノベーションにおける調達側の重要性を再認識することができた。
