即使香港已回归二十年，一直以来香港人仍然对他们的身份认同产生疑惑，与中国身份认同有关的社会问题不断爆发，进一步抑制了香港人对中国的爱国程度。同时，香港政府于2012年通过并实行“内地部分高等院校免试招收香港学生计划”，将其作为提升香港青少年对中国大陆爱国程度的一种方法。在这项研究中，我们重点揭示内地香港大学生的多重社会认同，文化适应策略和爱国主义之间的关系，以提示“内地部分高等院校免试招收香港学生计划”如何能有效加强香港大学生对中国的爱国主义程度。 105位来自北京、天津、上海、南京、武汉、四川省，及广东省七个城市和省份的香港本科生（男35，女70人）有效地参加了研究。所有被试都通过在线调查完成了多重身份认同，爱国主义和文化适应策略的问卷调查。之后了进行数据分析，检验了多重身份认同，文化适应策略，以及和爱国主义之间的关系，以及文化适应策略对爱国主义的中介作用。 目前研究的结果与假设一致。首先，随着对中国的认同增加，爱国主义程度也会增加。第二，随着对中国的认同增加，人们更倾向于使用同化策略来做出文化适应；对中国的认同较弱的人，则更倾向于使用分离策略。那么对于使用同化策略的人来说，他们对中国有更高的爱国主义程度；对于使用分离策略的人来说，对中国的爱国主义程度较低。最后，对中国有较强的认同将使个体更多地使用同化策略，导致了其对中国更高的爱国主义程度；对中国有较弱的认同将导致个体更多地使用分离策略，导致对中国的爱国程度较低。 随后本研究讨论了对研究的进一步应用和建议。

Even after the reunification with China in 1997, Hongkongers have always questioned about their identity, social issues related to the identification to China have constantly breaking out, which further hinder the patriotism of Hongkongers towards China. Meanwhile, ‘Scheme for Admission of Hong Kong Students to Mainland Higher Education Institutions’ was adopted by the Hong Kong government, which saw it as an alternatives to enhance the patriotism of Hong Kong adolescents towards Mainland China. In this study, we are focusing on revealing the relationships between multiple social identities, acculturation strategies, and patriotism of the Hong Kong undergraduates in Mainland, so as to give hints to how could the programme ‘Scheme for Admission of Hong Kong Students to Mainland Higher Education Institutions’ really work well on enhancing Hong Kong undergraduates’ patriotism towards China. 105 Hong Kong undergraduates (35 male and 70 female) from seven cities and provinces all over China, including Beijing, Tianjin, Shanghai, Nanjing, Wuhan, Sichuan Province, and Guangdong Province participated in the study. All of them completed the questionnaires of multiple social identities, patriotism, and acculturation strategies through online survey. After, data analysis is carried out to test for the relation between multiple social identities, acculturation strategies, and patriotism, as well as the mediating effect of acculturation strategies on patriotism. Results of current study are all consistent with the hypotheses. As predicted, as the identification towards China increases, patriotism degree would also increases. Next, with a stronger identification with China, one will be more tended to use assimilation strategy to acculturate; with a weaker identification with China, one will be more tended to acculturate with separation strategy. Then, for individuals who used assimilation strategy, a greater degree of patriotism towards China is recorded; for individuals who used separation strategy, will have a lesser degree of patriotism towards China. Finally, stronger identification with China will lead to more the use of assimilation strategy, resulting in a greater degree of patriotism towards China; weaker identification with China will lead to more the use of separation strategy, resulting in a lesser degree of patriotism towards China. The implication of study and suggestion for further research are then discussed.
