贸易成本与纯出口企业的异质性

Trade Cost and Heterogeneity of Pure Exporters

文章就我国存在大量的纯出口企业这一现象进行了研究,并根据Lu,Lu和Tao(2010)的方法对Melitz(2003)模型进行了扩展,把我国出口企业分为两类,分别就他们的出口、销售成本和出口决策过程进行了理论和实证研究。结果表明,已经在国内建有销售网络的企业,当其生产率足够高时,才进行出口;而新进入的企业由于出口的固定成本较低,低生产率企业首先选择出口,而生产率较高的企业才能进行国内销售。

This paper provides the analytical theory and empirical evidences for China＇s pure exporters. Following the method of Lu, Lu and Tao （2010）, an extension of Melitz （2003） is built to analyze the pure exporters. Firms are grouped, and marked as the incumbents or the new entrants; with different trade costs and sale costs, they have different decision systems with which to export. The incumbents as exporters have higher productivities than non-exporters, while the new entrants as exporters have lower productivities.
