Outline of Final Research Achievements

We proposed a production efficiency evaluation method for large energy companies after the deregulation of electricity and gas in the 1990s through redefining their innovation creation efforts and achievements, and conducted empirical analyses. Based on the multifaceted innovation creation activities of major energy companies, which acquire new energy, environmental, and digital technologies through R&D investments and mergers, we developed a production efficiency measurement method that incorporates these innovation factors and analyzed their impacts on efficiencies. We also extracted key factors from information on corporate social responsibility, the degree of environmental protection efforts, and participation in environment-related international initiatives obtained from various public documents and analyzed the relationship with managerial efficiency in terms of both changes over time and differences among companies.

Academic Significance and Societal Importance of the Research Achievements

本研究の学術的意義は、大手エネルギー企業の研究開発投資や特許の取得、合併等によるイノベーション創出活動を定量化し、それら要素を取り入れた生産効率性の計測について、データ包絡分析法（DEA）によるモデルを新たに提示し、実証分析を行うことで手法としての実用性を示したことにある。
本研究の社会的意義は、各種公開文書やデータベースから取得した企業の社会的責任（CSR）や環境保護への取り組み度合い、環境関連国際イニシアチブへの参加状況等を、統計的手法やテキスト分析の応用により多様に解析し、企業の経営効率性と社会的に望ましい環境配慮活動やイノベーション創出活動の関係を実証分析によって検証したことにある。
