摘要：

This study estimates the effects of technical barriers to trade (TBTs) on machinery imports in international production networks. Utilizing a gravity model with disaggregated, detailed product-level data, two different TBTs notifications measures are evaluated, namely, cumulative TBTs and a TBTs dummy. The empirical results indicate significantly negative effects on machinery imports. The evidence suggests that TBTs restrict the development of machinery production networks. However, this negative effect appears to come from the final product. In contrast, TBTs measures focused on parts and components have smaller negative effects than those focused on the final products for imports.
