本研究鎖定四個位處福佬—客家邊界但人口結構不同的地區，並根據1905–1945年的戶口登記檔案，分析40年間所有發生於當地的結婚事件。透過比較人口結構與福客通婚率的關係，本文揭開福客關係具有多種可能，並不像刻板印象那樣總是隔離或對立。此外，本文也分析雙親身分、婚姻形式、纏足偏好等因素如何影響福客通婚。嶄新發現如下：一、小婚（童養媳婚）最傾向採取族內婚，可能是為了避免姻親關係不足。二、纏足對福佬女性的束縛，包括阻礙他們與崇尚天然足的客家人通婚。

The marriage events from four areas around the Hoklo (Hokkien)-Hakka boundary that had distinctly different population structures were analyzed using the 1905–1945 household registration files. By comparing the association between population structures and the Hoklo-Hakka intermarriage rate, this research identified a range of possibilities within Hoklo-Hakka relations that suggests more nuanced dynamics than the stereotypical interpretations such as isolation or confrontation. Micro-level factors such as parental marriage types, forms of marriage, and foot-binding preferences were also taken into consideration to determine potential effects on Hoklo-Hakka intermarriage. New findings include the following. 1) Minor marriages (child brides) were preferentially intra-ethnic marriages, perhaps to avoid unsatisfactory degrees of in-law relationship. 2) Foot binding was an inhibiting factor for Hoklo women that lowered their chances of intermarriage with the Hakka people, who preferred women’s feet unbound.
