Outline of Final Research Achievements

This study uses the Vietnam Enterprise Survey between 2000 and 2015 to investigate impact of WTO accession (in 2007) on aggregate productivity of Vietnamese manufacturing sector. For this purpose, we examine changes in the production function, which represents relation between output and inputs (labor and capital), and changes in productivity of individual firms and the manufacturing sector before and after 2007. According to our results, the WTO accession caused changes in production structure of the manufacturing sector to raise productivity of individual firms, whereas it stagnated the aggregate productivity growth by weakening output reallocation effects, in which firms with higher productivity occupy higher output share in the sector.

Academic Significance and Societal Importance of the Research Achievements

本課題は、ベトナム製造業の企業レベルのパネルデータに基づき、同国のWTO加盟が製造業の生産性に与える効果を検証するが、WTO加盟年である2007年前後で十分な期間のデータを用いた研究、生産関数の推定により生産構造の変化を調べる研究はあまり見られない。また、推定結果に基づき、WTO加盟が生産構造にたしかに影響し、個別企業の生産性を高めたが、製造業全体の生産性を十分高められなかったことが明らかになり、製造業による成長に依存してきたベトナムには注目すべき結果となっている。
