本文基于移民网络变量考察了中国与28个样本国的双边贸易流,通过标准模型(STD)和成本对称模型(STC)的识别发现,3组指标(累积规模、相对规模和技能型移民网络)较一致表明移民网络对中国对外贸易具有积极贡献;研究还发现移民网络的成本克服效应在新兴经济体(拉美和非洲)更为显著,即移民网络更为稀缺;而贸易创造的移民消费偏好效应在亚洲和北美更为突出,表明华侨移民集聚规模的重要性。
Based on the variables of immigration network, this paper examines the bilateral trade flows between China and 28 sample countries. Through the identification of STD and STC, it is found that three indicators (cumulative scale, relative size and skilled immigration network) The more consistent evidence shows that immigration networks make a positive contribution to China’s foreign trade. The study also found that the cost-to-effect effect of immigration networks is more significant in emerging economies (Latin America and Africa), ie immigration networks are more scarce; while the trade-created consumer preferences More prominent in Asia and North America, indicating the importance of the scale of overseas immigrants gathering.
