【摘要】 基于非位似偏好的贸易理论研究表明,收入分布将会通过需求结构影响一国的进出口商品结构。本文通过包含了需求结构因素的重力方程对我国与主要贸易伙伴国在分档次消费品双边贸易中是否存在本地市场效应进行检验。结果表明,同一门类下不同档次产品的本地市场效应存在差异;同时,需求结构随需求规模在不同区间呈现对本地市场效应的差异化影响,其政策含义是,适应并合理利用当前的收入分布状况和需求结构,尽快挖掘立足本土需求的内生驱动因素,减少对外部环境的依赖,实现产品本地市场效应。更多还原

【Abstract】 The theory of trade based on non-homothetic preferences shows that,the income distribution will influence a country’s import and export commodities structure through the demand structure.We use a gravity approach which contains the income distribution factors to examine the existence of home-market effects in China.The results show that the home-market effect relies on both demand scale and demand structure.This means that China should take advantage of the existing demand structure appropriately to excavate the potential of home-market effects.更多还原
