本研究採取歷史制度論的觀點，探討影響屏東榮家的制度變遷的外在動因與內在動因；並從時間序列分析屏東榮家組織變遷不同階段的變革特色，以及不同階段的組織變革對於社會照顧專業發展之影響。研究方法採取內容分析法與深度訪談法，蒐集有關榮家變遷的相關資料。本研究的重要發現如下：一、在歷史脈絡下的外在與內在動因分析面向上：屏東榮家組織變遷受到內、外在動因交互作用所影響，在外在動因上有政治、經濟、社會三大要素；在內在動因上主要來自組織文化、專業制度與住民需求三種因素。二、在組織變遷階段與特色面向上：可分為開創時期（1950年-1979年）、精進發展時期（1980年-1989年）、專業多元時期（1990年-迄今）等三個階段。透過此三階段的時間序列分析，發現了組織變遷的過程反映了歷史制度論者所論述制度並非長久不變，決策關鍵點會不斷調整其結構限制，形成一種斷續式的均衡。三、在組織變革對照顧專業服務發展之影響面向上：第一階段開創時期在專業服務上「以就業為主，救濟為輔」的模式；到了第二階段的精進發展時期，朝向「人性關懷與權益保障」的福利思維發展；進入第三階段專業多元發展時期，朝向「社區化」的政策方向發展。四、在屏東榮家作為社會照顧機構的特色面向上，主要有三方面：（一）組織的制度特色，包含組織領導者風格、「同儕領導」的模式、延續軍中的管理模式。（二）組織的文化特色，包含「榮家」具有情感召喚的意義、榮民習慣於規律的生活模式、榮民兩岸情結逐漸淡化。（三）專業服務特色，包含同時兼具「安養」與「養護」兩大專業照顧主軸、對專業人力的規範、服務人員多為榮民第二代。
