提升出口产品质量是我国出口贸易转型升级的关键环节。本文考察了劳动力集聚对出口产品质量的影响。研究发现，集聚经济不仅对城市出口产品质量有显著正向影响，而且在不同所有权和贸易方式下的影响程度存在差异。在用工具变量法和GMM解决内生性问题后，本文的结论依然稳健。

It is important to improve the quality of export products for Chi- na to transform and upgrade its foreign trade mode. This paper investigates the influence of agglomeration on the quality of export products. The results show that agglomeration has a significantly positive influence on the quality of export products in the studied cities, while this influence varies with different owner- ships and trade patterns. The above results remain robust after controlling poten- tial endogeneity using the instrumental variables method and the GMM method.
