回归以来，澳门青年人的国家认同始终处于极高的水平。相比之下，香港青年人的国家认同水平则经历了先上升、后下降又回升的曲折变化。与较年长群体相比，香港青年人的国家认同水平略低，这与该群体本身的一些特征有关。比如：他们往来内地的频率远低于较年长群体，这可能导致他们对国家缺乏了解；他们对内地人来港购物和工作的态度较为负面，这可能导致他们将日常生活中对内地人的消极印象投射为对国家的负面认知；他们习惯使用社交媒体等互联网媒体获取信息，其所获取的关于国家的信息可能有限或者失真。此外，就香港本地治理而言，香港青年人将“民生”和“法治”看作未来五年最重要的政府治理目标，而非很多“反对派”政治力量所鼓吹的民主政治体制改革。香港青年人的国家认同背后隐藏的是复杂的经济和民生等本地治理问题，并非根深蒂固的价值性和政治性矛盾。
Since the handover，the national identity of young people in Hong Kong has steadily increased in the first decade，followed by a continuous drop in the next several years.It has shown，however，a gradual upward trend in the recent years.Compared with the elder group，the national identity of young Hongkongers is relatively weaker.This is closely related to some key features of the group itself.Firstly，the frequency of young Hongkongers moving to the Mainland is much lower than that of the elder group，which may lead to their lack of understanding of the country.Secondly，young Hongkongers have a more negative attitude towards the mainlanders shopping and working in Hong Kong，which may dampen their affective feelings on the county.Thirdly，young Hongkonger more likely to rely on social media and other Internet media to obtain information，and the information they obtain about the country may be limited or distorted.In contrast，the national identity of young people in Macau is much stronger than that of their Hong Kong counterpart.
