Abstract This study examines the effects of logistics infrastructure on export variety, as measured by the extensive margin. Using finely disaggregated exports data for Turkey’s trade with 174 countries over the period 2007–2017, we decompose gross export flows into the extensive and intensive margins of Turkish exports utilizing the method developed by Hummels and Klenow (2005). Gravity estimates suggest that logistics infrastructure positively influences export values and has a greater impact on the extensive margin than the intensive margin. Our empirical analysis further suggests that Turkish exporters are more sensitive to changes in local market logistics conditions than to those of their trade partners. These findings are robust to a variety of alternative measures and estimation methods.

物流绩效和出口品种：来自土耳其的证据

摘要 本研究考察了物流基础设施对出口品种的影响，以粗放边际衡量。使用 2007 年至 2017 年期间土耳其与 174 个国家的贸易的精细分类出口数据，我们利用 Hummels 和 Klenow（2005 年）开发的方法将总出口流量分解为土耳其出口的粗放和集约边际。重力估计表明，物流基础设施对出口价值有积极影响，对粗放边际的影响大于集约边际。我们的实证分析进一步表明，与贸易伙伴相比，土耳其出口商对当地市场物流条件的变化更为敏感。这些发现对各种替代措施和估计方法都是稳健的。
