As a racialized pan-ethnic group, Asian Americans exhibit ethnically heterogeneous structural and cultural characteristics, but such heterogeneity and its implications for Asian Americans’ pan-ethnic groupness were seldom explored empirically. Using the American Community Survey and the 2016 National Asian American Survey datasets, this paper examines intra-Asian symbolic and socioeconomic boundaries and boundary processes captured in Asian interethnic marriage. I find prominent intra-Asian boundaries distinguishing exceptionally disadvantaged refugee-origin Southeast Asians, yet intra-Asian marriages still occur across these boundaries. This mismatch between intra-Asian boundaries and marriage patterns reflects loose and often unstable interpretations of ethnic similarities and differences. Together, my findings reveal Asian Americans’ contextually salient interpretations of ethnic heterogeneity behind intra-Asian boundary processes, which further reinforce the socially constructed notion of Asian Americans as a racialized group.

作为一个种族化的泛民族群体，亚裔美国人表现出种族异质性的结构和文化特征，但这种异质性及其对亚裔美国人泛民族群体的影响却很少被实证研究。使用美国社区调查和 2016 年全国亚裔美国人调查数据集，本文研究了亚洲内部的象征和社会经济边界以及亚洲种族间婚姻中捕获的边界过程。我发现突出的亚洲内部边界区分了极其不利的东南亚难民，但亚洲内部的婚姻仍然跨越这些边界。亚洲内部边界和婚姻模式之间的这种不匹配反映了对种族异同的松散且经常不稳定的解释。一起，
