国内市场分割与中国的出口贸易扩张

Market Segmentation and the Expansion of China's Export

本文将国内市场分割和边际成本与固定成本之间的反向关系引入Melitz(2003)的模型,构建了一个开放经济模型。文章证明了国内市场分割导致不同生产技术的企业都首选进入国外市场。这似乎解释了中国出口贸易的强劲增长其实是严重的国内市场分割导致企业无法依托巨大的国内需求、发挥规模经济而被迫出口的扭曲现象。

This paper discusses the market segmentation extension of Melitz （2003） open economy model by introducing the inverse relationship between the fixed cost and the marginal cost. It shows that firms with different kinds of technology all prefer to export when entry costs of the home market are very high. This property may explain that severe market segmentations produce the distortion that Chinese private firms try to explore oversea market instead of home market, which results in rapid expansion of China＇ s export.
