本文的主要目的在於探討1950年左右近百萬的外省移民進入臺灣後，因為性比例
的不均衡所推動的第一代省籍通婚，對於省籍族�擐P化的影響。除了本人是否通婚對於第一
代自身的影響外，本文也討論了父母是否通婚對於外省第二代的影響。至於影響的層面，則
包括語言、自我認定、及對於和省籍族�擐傢鰝瘧傢D等族�擐P化的面向。本文整理了西方文
獻中，對於族�曈q婚與族�擐P化的兩種主要的說法－「同化論」及「多元論」，作為分析的
理論架構。本文以 1991 年「臺灣地區社會意向調查」及 1992 年「臺灣地區社會變遷基本
調查」的資料進行分析的結果，發現：（１）第一代的省籍通婚僅對通婚的本省女性造成單
方向的影響；（２）父母是否通婚對於第二代外省人在族�擐P化上並無顯著影響；（３）族
�撉漪F治競爭干擾或抵銷了族�曈q婚對於外省人族�擐P化的影響。根據這些發現，本文檢討
了同化論及多元論在解釋臺灣第一代省籍族�曈q婚的後果上的不足之處。本文指出，省籍族
�擐b語言、認同、及族�樾傢D上的同化，事實上是受到整個大社會中，團體層次的族�橨鰜Y
之影響。因此，我們很難期望族�曈q婚所導致的個人或家族層次的族�敼腔瓷A能產生同化論
所描素的族�擐P化之後果。

Ethnic intermarriages between the Taiwanese and the Mainlanders in
Taiwan before 1971 has been characterized by the predominant pattern of
"Mainlander male marrying Taiwanese female," as a result of extremely high sex
ratio (three men to one women) among the a million mainland immigrants who
entered Taiwan around 1950. Consequently, over a half of the second generation
mainlanders have Taiwanese mothers. This paper aims to explore the impacts of
such ethnic intermarriages on ethnic assimilation in Taiwan. Besides the effects
of intermarriage on the couples, it also deals with the effects on the children
of those intermarriages. The effects examined include: assimilation in
languages, ethnic self-identity, and attitudes in regards to ethnically-related
issues. This paper draws on the "assimilation model" and the "pluralist model"
to explain the impacts of ethnic intermarriages on assimilation. Although they
both agree that intermarriages bring about cultural assimilation, the two models
diverge in their predictions of maintaining ethnic identity under cultural
assimilation. By analyzing the 1991 "Social Image Survey" and the 1992 "Social
Change Survey" data sets, it is found that: 1) the first generation
intermarriages only have one-sided effects on the Taiwanese women, but not their
mainlander husbands; 2) parents' intermarriages do not seem to have significant
influence on the second generation mainlanders; and 3) the slight effects of
intermarriages on the Mainlanders are counteracted by the rising ethnic
political competition, especially after 1991. Based on theses findings, the
author discusses the inadequacies of both assimilation model and pluralist
model. This paper argues that the examined dimensions of ethnic assimilation is
more a result of macro-level ethnic relations than the micro-level ethnic
contacts. We therefore can hardly expect the micro-level ethnic contacts in the
family would have significant impacts on ethnic assimilation, as the
assimilation model would lead us to believe. The pluralist model fails to
provide an explanation for the one-sided effect of intermarriages on Taiwanese
because it does not take the imbalance power relations between the two ethnic
groups into account.
