韓國在經濟起飛後，國民的生活品質愈來愈高，開始有能力做高消費的文化行為，文創產業得以蓬勃發展，而其中一支係為「音樂劇產業」。韓國的音樂劇的發展主要分為兩大類，分別係授權音樂劇以及原創音樂劇（亦稱創作音樂劇）。
本論文旨在探討韓國的音樂劇產業，並往外延伸，從原創音樂劇「洗衣」來探視韓國的社會問題。主要論文架構分為兩大部分，第一部分係由數據來看韓國的音樂劇產業規模，以及與音樂劇相關的產業發展；第二部分則做進一步延伸，從「洗衣（빨래）」一劇中出現的社會背景，來探究劇中突顯的韓國社會問題，並就反映的社會問題來做分析和實例檢證。
透過本論文研究結果得知，可以得知韓國音樂劇產業的發展規模會繼續擴張，透過促成產業發展的製作公司、劇作、演出場地、演員和閱聽人，音樂劇產業只會愈來愈繁榮，而當作品完成度高時，就會有被買走授權的機會，「洗衣」即是如此。通過「洗衣」，可以看見愛情故事背後，韓國社會所存在的問題：非法資遣與移住勞工。本論文之研究結果期望能對韓國音樂劇產業感興趣或想進一步了解韓國音樂劇產業的讀者，希冀能有一絲助益。此外，亦對韓國的非法資遣、移住勞工問題有進一步的了解。
