社區照顧政策在臺灣已實施超過十年，照顧的混合式經濟是其中的主要焦點，此種混合式經濟包括二個重要意義－一是有給的居服員與志工居家服務的混合式經濟，另一個是正式部門與非正式部門照護服務的混合式經濟。本研究係特別針對臺灣省區域之居家照顧服務(DCS)所做之研究。其基本資料係來自臺灣省獨居老人中l,464人對此服務之使用滿意度之電話調查，藉此以了解其對居家照顧服務 (DCS)有給的居服員與志工不同滿意度之差異，並呈現受服務後正式與非正式部門間關係情形。研究中發現，有關受訪者部分基本變項之不同而在平均滿意度上有顯著性差異；而獨居老人對不同的居家服務工作者亦有不同之滿意度，受志工服務者表現最低之滿意度，而兼職居家服務工作者亦較全時居服員之滿意度爲低。另外，依據迴歸模型分析研究結果顯示，在居家照顧服務(DCS)領域中，正式部門與非正式部門之間其關係對非正式部門僅有補充性效果而無替代性效果。

The policy of community care has been put into practice for more than ten years in Taiwan. The mixed economy of care is the main focus in its policy. There are two important meanings of the mixed economy of care-one is the mixed economy of paid and volunteer care services, another is the mixed economy of the informal and formal sectors. This research deals with these especially on domiciliary care service (DCS) in Taiwan Province. The database of this research consists of replies from 1464 elderly people who are living alone in Taiwan Province to answer questions about the extent of their satisfaction with the DCS. The different levels of satisfaction between paid and unpaid DCS workers and the relationship between the formal and informal sectors are revealed, in the research, with regard to respondents' satisfaction, some differences in mean satisfaction between different basic characteristics of respondents are evident. With the different types of care worker, those served by volunteer care workers score least in satisfaction and those served by part-time care workers have a lower satisfaction score than those served by full-time workers. According to the regression analyses, it reveals the existence of a supplementary effect but not a substitute effect between the formal sector and the informal sector in terms of DCS. In addition, a quasi-market model, or public-led provision may be identified in the mixed economy of care in the research.
