This paper examines network structure and composition in international migration diffusion. Using original data from a rural village in the Philippines, it combines social network analysis and descriptive approach to arrive at a set of propositions about why some initial migration lead to expansion while others do not. It argues that migration diffusion is attributed, in part, to the dispersed distribution and strategic position of pioneers in the network at the beginning, which allowed a seemingly even migration expansion as pioneers facilitated subsequent migration activities. Had the initial context fostered pioneer migration to transpire only among few families, and if pioneers were positioned less centrally, the outcome might have been a less extensive diffusion. Furthermore, the analysis shows that migration is more likely to diffuse among members of a family cluster and might cease to diffuse at the border of their inner social circles.

外迁行为如何在原籍社区内级联？使用菲律宾案例的移民网络分析的社会历史方法

本文考察了国际移民扩散中的网络结构和组成。使用来自菲律宾农村的原始数据，它结合了社会网络分析和描述性方法，得出了一组关于为什么一些初始迁移会导致扩张而另一些不会导致扩张的命题。它认为，迁移扩散部分归因于先驱者在开始时在网络中的分散分布和战略地位，这使得随着先驱者促进随后的迁移活动而看似均匀的迁移扩展。如果最初的背景促使拓荒者迁移只在少数家庭中发生，并且如果拓荒者的位置不那么中心化，那么结果可能是不那么广泛的传播。此外，
