Determinants of Iran’s Bilateral Intra-industry Trade in Pharmaceutical Industry

Among non-oil and in trade arena, drug has always been strategic importance and most government especially industrialized countries pay special attention to its production and trade issues. thus, having a comprehensive view from economic perspective to this section is essential for suggesting intervention. this was a descriptive-analytical and panel study. in this study, gravity model is used to estimate iran’s bilateral intra-industry trade in pharmaceutical products in the 2001-2012 periods. to illustrate the extent of pharmaceutical’s intra-industry trade between iran and its major trading partners, the explanatory variables of market size, income, factor endowments, distance, cultural contributions, and similarities and also special trade arrangements have been applied. analysis of factors affecting iran’s bilateral intraindustry trade in pharmaceutical industry showed that the average gdp and cultural similarities had a significant positive impact on iran’s bilateral iit, while the difference in gdp has a negative and significant effect. coefficients obtained for the geographical distance and the average ratio of total capital to the labor force is not consistent with theoretical expectations. special trade arrangements did not have significant impact on the extent of bilateral intraindustry trade between iran and its trading partners. the knowledge of the intra-industry trade between iran and its trade partners make integration between the countries. factors affecting this type of trade pattern underlie its development in trade relationship. therefore, the findings of this study would be useful in helping to develop and implement policies for the expansion of the pharmaceutical trade.
