摘　　要：从异质性移民网络和出口产品质量视角,使用引力模型验证了移民网络对中国出口贸易的影响机制主要体现在“信息成本”“移民偏好”及“进口替代”上。第一,通过“移民偏好”与“信息成本”机制,移民网络提升了中国中-高质量产品的出口;往北方国家的移民网络通过“进口替代”机制,降低了中国出口的低质量产品。第二,非商业移民网络对中国出口的促进作用要比商业移民网络更为重要,其中往南方国家的非商业移民网络体现出最为明显的贸易促进效应。第三,移民受教育程度越高,对中国出口的中-高质量产品的促进效应愈加明显,体现出明显的“信息成本”机制;中等教育及以下移民主要通过“移民偏好”机制促进中国高质量产品的出口,而且增加中等教育及以上移民比例会进一步强化对中国出口的促进效应;高等教育移民对中国出口的低质量产品产生明显的“进口替代”效应。第四,25~64岁移民对中国出口的中-高质量产品产生的促进效应最为明显;15~24岁及65岁以上移民则通过“移民偏好”机制,促进了中国高质量产品的出口。By using heterogeneous emigration and export quality information,this article testified the influence mechanism of migration network on China’s export trade,which is reflecting in“information cost”,“migration preferences”and“import substitution”.Firstly,migration network has promoted China’s exports of medium-high quality products through the mechanism of“migration preferences”and“information cost”,but decrease the export of low-quality product through the mechanism of“import substitution”by migration network to northern countries.Secondly,non-business migration network plays a more important role in promoting China’s exports than commercial migration network,among them,non-business migration network to southern countries has a more positive effects on China’s export.Thirdly,the higher education level of migrant,the more obvious promotion effect on exports of medium-high quality products,reflecting obvious“information cost”mechanism.Migrants with secondary education and below promote China’s export of high-quality products mainly through the mechanism of“migration preference”,and increasing the proportion of migrants with secondary education and above will further strengthen the promoting effect on China’s export.Higher education migration has a obvious“import substitution”effect on low-quality products exported from China.Fourthly,migrants between 25~64 years old has the most obvious promotion effect on China’s export of medium and high-quality products.Migrants between 15~24 years old and aged 65 years and above promote China’s exports of high-quality products through the“migration preference”mechanism.
