摘要

本文建立了一个具有企业异质性的两国寡头垄断模型，研究了市场规模、本土市场效应和引力方程之间的关系。我们的研究表明，在自由进入的长期条件下，本土市场效应成立，即更多的企业在规模大的国家落户。这导致大国成为寡头产品的净出口国。在限制进入的短期，本土市场效应不再成立，大国成为寡头产品的净进口国。这些结果表明，Feenstra 等人（Can J Econ 34(2)：430-447，2001 年）的理论预测经得起企业异质性的考验。

Firm Heterogeneity, Home Market Effect, and Gravity Equation in an Oligopoly

Developing a two-country oligopoly model with firm heterogeneity, this paper examines the relationship among market size, the Home Market Effect, and the gravity equation. We show that in the long-run with free entry, the Home Market Effect holds, namely, more firms locate in the large-sized country. This leads the large-sized country to be a net exporter of the oligopoly good. In the short-run with restricted entry, the Home Market Effect no longer holds and the large-sized country becomes a net importer of the oligopoly good. These results suggest that the theoretical predictions of Feenstra et al. (Can J Econ 34(2):430–447, 2001) survive firm heterogeneity.
