Determinants of product sophistication in Vietnam: findings from the firm–multi-product level microdata approach

Abstract

ABSTRACT By using data from the Vietnam Enterprise Survey and applying the fixed effect model, this study investigates the determinants of product sophistication at the firm – multi-product level in Vietnam-a transitional economy – over 2010–2016. Estimations show that horizontal foreign direct investment (FDI) spillovers have a negative effect on product sophistication. We find a positive contribution of forward spillovers and a negative contribution of backward linkages. An interaction term between forward spillover and productivity has a negative effect but is insignificant. Estimated outcomes also indicate that the average amount of labour, revenue, productivity, technology level, and capital to labour ratio of firms has advantageous impacts on product sophistication. Our results are robust using different measurements of product sophistication. This article suggests that strengthening forward linkages by facilitating the supply of intermediate inputs from multinational firms and improving productivity, capital-to-labour ratio, and governance capability could help Vietnamese firms produce more sophisticated goods.
