Abstract

This paper develops a monopolistic competition model of multi‐product firms to explain the effect of trade liberalization on the product mix of multi‐product exporting firms. The model shows that input‐tariff reduction leads to increases in a firm's export values, especially for products that are farther from a firm's core competency. To test the theoretical predictions, we use the merged data built upon the highly disaggregated Chinese firm‐level production data and customs data for 2000–2006. Consistent with the theory, the positive impact of input trade liberalization on export value is found to be more pronounced for peripheral products, and input‐tariff reduction also expands a firm's product scope, affecting firm's average productivity. Libéralisation des importations et gamme de produits d'exportation. Dans cet article, nous développons un modèle de concurrence monopolistique d'entreprises diversifiées afin d'expliquer les effets de la libéralisation du commerce sur les gammes de marchandises proposées par ces sociétés « multi‐produits » exportatrices. Ce modèle montre que pour les entreprises, la baisse des droits de douane sur les intrants entraîne une augmentation de la valeur de leurs exportations, notamment pour les produits les plus éloignés de leurs compétences de base. Pour vérifier ces prédictions théoriques, nous utilisons des données fusionnées élaborées à partir de ressources très détaillées relatives à la production des entreprises chinoises et aux transactions douanières entre 2000 et 2006. Conformément à la théorie, l'impact positif de la libéralisation du commerce des intrants sur la valeur des exportations des entreprises est davantage marqué pour les produits périphériques. La baisse des droits de douane sur les intrants leur permet également d'élargir leur gamme de produits, ce qui n'est pas sans conséquence sur leur productivité moyenne.
