Outline of Final Research Achievements	The global turmoil caused by the novel coronavirus (COVID-19) has led to curfews and travel restrictions in many countries. This disrupted production in many countries, caused ports and other places to shut down, and had a significant impact on modern economic systems that rely on multilateral supply chains.　This also had a significant impact on Japan, bringing unprecedented changes to the international trade environment of Japan, which is heavily dependent on international supply chains, including disruptions at loading ports, destinations, ports and transportation, and domestic production and transportation. In particular, the import disruption has also affected the employment situation. As a result of the analysis, it was found that during the period when the impact of COVID-19 in the Japan was large, there was a special tendency compared to the period before and after it, and it was likely that multiple vibrations occurred while influencing each other.

Academic Significance and Societal Importance of the Research Achievements	本研究はグローバルなサプライチェーンの変化が我が国の雇用にどのような影響を与えるのかを貿易統計を用いて実証的に示す研究であり、分析のための新たなモデルおよび解析分析信号手法などの多様な分析手法を適用し、かつ明瞭な結果を得たことで経済学分野での手法の新しさも含め学術的に意義あるものである。また、すでにグローバル化した我が国の産業構造が国際経済の変動によって、我が国の雇用そのものにどのような影響を与えるかを数値的に示したものであり、雇用問題という重要な社会課題に対しての重要な指針を与えるものであることから社会的な意義も大きいものであると考える。
