中文摘要：

基于全球价值链理论，选取三家加工贸易型企业和三家专业外贸公司进行跨案例研究，探讨我国外贸企业国际化转型的机制和路径。研究发现，分属生产者驱动和购买者驱动的两类外贸企业，分别采取自有品牌制造（OBM）、业务流程外包（BPO）等多种嵌入路径，通过价值链上下游嵌入、原价值链环节深度嵌入和新价值链嵌入三种方式实现全球价值链嵌入环节的改变与升级，同时带来外贸企业供应能力、交易复杂性和资源承诺等动态因素的变化，进而影响企业嵌人全球价值链的治理模式和角色演变，实现国际化转型。基于“全球价值链嵌人一升级一治理模式演化”的理论框架提炼出外贸企业的国际化转型过程；提出制造一服务一体化整合、低价值链高端嵌入两条创新路径。

英文摘要：

This study based on the theory of global value chain, selected three manufacture companies and three professional Interna tional Trade Companies as the sample, studied the six cases about their transformation problems, and analyzed the mechanism and paths of transformation. We found that buyer driven and producer driven enterprises, respectively adopt specific paths such as origi nal brand manufacturer（OBM） ,business process outsourcing （BPO） take the three ways to change the global value chain and upgra ded： up or down stream embedded in original value chain, embedded in original value chain deeply and embedded in the new value chain. Changed the dynamic factors such as deliverability, complexity of transaction and resource commitment, then change the govern ance types and the role, realize the internationalization transformation. This study sums up the transformed ways and the paths of inter national trade enterprises based on the framework of embedded global value chain, transformation and governance types evolution, and put forward two new ideas of transformation： the manufacture service integration and high end embedded in low value chain, this study provides the practice suggestions for the foreign trade companies simultaneously.
