Professor Lin Wan-i of National Taiwan University's Social Work Department points out that a third of all foreign brides under the age of 20 tend to be physically, emotionally and socially immature. They are on average three to five years behind their Taiwan counterparts educationally. Not only is their own competitive advantage low, it adversely affects the rearing of their children and creates the problem of continued weak competitiveness for the next generation.
台大社工系教授林萬億指出，這三分之一未滿二十歲的外籍新娘，在身心或社會化發展的成熟度都比較低；而她們受教育程度平均比台灣女性少三到五年，可以說不僅自身競爭力低，也不利於下一代的教養，將造成競爭力低落問題延續到下一個世代。
