所謂「交往詩」，涵蓋酬贈、唱和、贈別，及文人間往來交涉各類型詩篇。在李頎八十多首交往詩中，以酬答、送別數量為多。 李頎在寫作交往詩時，有別於一般詩人之著重抒情、敘別；李頎喜描述往來友人之獨特性格、超凡襟抱與特異行徑，而且敘、寫兼行，富於典型義意；在人物形象描述方面，頗有特色。 通過本文考察，李頎之交往詩，以酬贈狂狷之士，最為突出。這些人物，大都生活在唐玄宗開元、天寶年間。透過李頎巧筆傳述，形神畢現、活躍眼前。其詩友事蹟豐富、生涯曲折者，李頎更是詳細鋪敘、不避瑣碎，其人格形象，更為凸顯。 通過李頎之交往詩，吾人不但可以賞鑑盛唐人物之美，部分詩篇所鋪陳之事蹟，更有助於中國文學史家對唐玄宗開元、天寶人物之察考；從而使這些詩篇，具有一定的文學史料價值。
