Outline of Final Research Achievements

This research project investigates how Corporate Social Responsibility(CSR), especially Environmental Corporate Social Responsibility(ECSR) affects the market structure and economic welfare in oligopolies. I show that each firms and industry group have incentives to adopt ESCR even when ECSR does not increase their demand or does not reduce capital costs, and the level of ECSR is higher when the industry group leads it. However, such ECSR may harm welfare even when I fully consider the social costs of environmental damages. I also show that emission cap commitment is more likely to harm welfare than emission intensity commitment. Moreover I find that in imperfectly competitive markets, the emission intensity commitment is always better for welfare than the emission cap commitment for implementing a near net-zero emission society.

Academic Significance and Societal Importance of the Research Achievements

企業の環境問題への自主的取り組みであるESCRの重要性は今後更に高まると予想されている。しかし、企業の環境問題への取り組みは、寡占市場においては競争制限効果を持ちかねず、消費者および社会の利益を損なう可能性もある。業界団体が主導する取り組みはさらにその危険性が高くなる。本研究プロジェクトで、相対的に弊害の小さな(経済厚生改善効果の大きな)取り組みは、製品一単位当たりの排出量を抑制する排出原単位へのコミットメントであることを明らかにし、更にこの意義はネットゼロエミッション社会ではより大きいことを明らかにした点で、企業の環境活動への評価や、その先の環境政策のあり方にも重要な示唆を与えている。
