Outline of Final Research Achievements	This research investigates the impact of dual job-holding on occupational mobility. The skills accumulation for occupational mobility has been pointed out as one of the motives of dual job-holding. In this research project, we empirically explore and analyze how transferable skills acquired through dual job-holding function and help for successful occupational mobility. First, we obtain empirical results suggesting that previous experiences of dual job-holding or skills gained through dual job-holding may affect the determinants and directions of occupational mobility, and moreover downward/upward career switches on the skill ladder, which is vertical ranking of occupations, in Estonia’s economic transition. Furthermore, we clarify current peculiarities of dual job-holding in the Japanese labor market in comparison with those in U.S. labor market.
Academic Significance and Societal Importance of the Research Achievements	本研究における、過去の副業経験の職業移動（転職）への影響の分析は、未だ先行研究が薄い。労働市場における需要と供給のミスマッチの解消に対して、副業の経験や職能が職業移動を通して果たす役割を、エストニア、日本という特性が異なる労働市場に対して示唆することは、学術的・政策的意義がある。近年の日本では、働き方改革とあわせて、副業・兼業の普及促進が図られ、副業従事率の上昇、副業保有動機や副業が果たす役割の変化が期待される。このような中、日本の副業保有の特性を明らかにし、副業保有が職業移動において果たしうる機能を考察することは、副業増加が労働市場にもたらす変化の予測にもつながり、社会的貢献があるといえる。
