Academic Significance and Societal Importance of the Research Achievements

まず、最低賃金は労働政策の中で最も重要な政策の1つとして注目されるため、先進国を対象とする実証研究は盛んであるが、中国を対象とした研究が少なかった。本研究は最低賃金が都市住民と出稼ぎ労働者の賃金格差に与える影響に着目し、最低賃金の効果に関する新たな根拠を提供できた。本研究はこの課題に関する初めての研究として学術的意義が大きいと評価できる。次に、社会的意義については、本研究は企業調査を実施した結果、所有制形態によって賃金制度が異なる事実を発見した。これらの研究成果に基づいて、最低賃金制度の実施におけるコンプライアンス問題に関する対策を提言し、また中国に進出する日本企業に新たな資料を提供できた。
