Beginning in 2000, the Chinese TV broadcasting authorities issued clear written guidelines specifying the permissible proportion of Hong Kong and Taiwanese staff in film crews. For prime time "national production" TV dramas, at most there can be only two Hong Kong or Taiwanese actors, and Hong Kong and Taiwanese producers and directors can not be credited.
二○○○年起，中共廣電局開始明文規定台港戲劇工作人員比例：可以登上電視黃金檔的「國產劇」，演員最多僅能有兩位台港人士，台港製作人與導演更不得在劇上掛名。
