本文主要是經由普及服務概念之探討，來界定郵政事業中微觀的普及服務和宏觀的普及服務之具體內容。同時，藉由德法英等西歐國家的經驗和日本現況的探討，來瞭解其他國家在面臨郵政事業自由化、民營化之時，所採行的郵政普及服務之確保方式。 從普及服務的觀點來分析國外的郵政事業改革經驗發現，有下列三點可作為我國參考：第一、郵政普及服務概念的具體化、法制化；第二、郵政改革是採取部份自由化和漸進自由化；第三、郵政普及服務基金的設置。

　　　　　This study aims at defining the concrete content of micro- and macro- universal service in postal service through an exploration on the concept of universal service, and at the same time, achieving an understanding of the security methods for postal universal service adopted by means of exploration on experiences from Germany, France and England, etc., and status of Japan while other countries face the reformation of liberalization and privatization for postal service. An analysis on overseas reformation experience from a perspective of universal service security has led to three points for our reference as follows: first, concretion and legalization for the concept of universal service; second, partial liberalization and progressive freedom; third, an institution of postal universal service fund.
