楊牧與香港有千絲萬縷的關係，但過去鮮少有論文觸及他的香港書寫，以及他在臺港文學跨區域傳播的影響。本文透過作家生平與作品的對照，發現楊牧壯年時期，重要的詩集《時光命題》，以及散文集《疑神》與《亭午之鷹》，均寫作在他寓居香港期間，藉由分析他含蓄與抽象思維的寫作，可進一步理解楊牧人文精神的高度與憂思。同時本文也耙梳楊牧臺港文學跨區域傳播影響的現象，分別從他在香港獲得的評論與介紹，以及六次擔任香港中文文學雙年獎評審，肯認他在香港文壇的經典地位與影響力。

Though heavily connected to Hong Kong, seldom essays shedded lights on Yang Mu’s（楊牧）HK writings and his influence on Taiwan and HK Cross-regional literary communication. By relating Yang Mu’s lifetime experience to his compositions, this essay discovers that most of his critical works among middle-age such as poet collections “Propositions in Temporality: Collected Poems”（時光命題）, prose collections “The Skeptic: Notes on Poetical Discrepancies”（疑神）, and “The Midday Hawk”（亭午之鷹）are all completed in HK. This essay believes by analyzing Yang Mu’s implicit, abstract writing skills, people could realize his Humanitarianism concern more. In the meantime, this essay addresses Yang Mu’s influence on Taiwan and HK literary communication and reaffirms this six-timers "Hong Kong Biennial Awards for Chinese Literature” judge’s paramount status in HK literature from critics, reference issued in HK.
