本研究所要探討的課題主要有以下三點：1.現行國宅等候制度有何缺失？應如何改進？2.我們由台灣省各縣市等候名冊申請登記戶數情形可以看出，目前國宅需求集中在政府直接興建國宅，而輔助人民貸款自購住宅之需求則相對較少，其背後原因為何？應如何改進？3.各縣市國宅資源是否真的不足？目前以供給面的政府直接興建國宅為主的住宅補貼措施是否適當？應如何改進？

　　為針對以上問題加以解答，本研究首先以國宅等候制度在實際執行上所應發揮的三項功能：掌握國宅需求、決定國宅資源分配順序與提供人民充分資訊為觀點，對現行國宅等候制度加以檢討，最後並對我國國宅等候制度未來的改進方向提出具體的建議。

　　其次，本文以國宅需求量本身之決定因素（資格、意願、負擔能力）作為研究基礎，以臺灣省21縣市為實證範圍，估計歷年國宅需求量，進而探討影響國宅需求量變動的各種因素，特別強調不同補貼額度對國宅需求量的影響，透過計量經濟分析方法，最後驗證了補貼額度與國宅供給速率對於國宅需求量確實存在有顯著的影響。

　　最後，本研究以資源公平效率分配的觀點，配合國宅供需現況，以模擬分析的方式對臺灣省二十一縣市的國宅資源分配加以試算，結果發現，各縣市國宅供需失衡之主要原因不在國宅資源不足，而是在資源分配之不當，若將供給面補貼的政府直接興建國宅資源部分分配到需求面補貼的輔助人民貸款自購住宅，大部份縣市均能在短期內解決其國宅供需失衡問題，且可有多餘的資源用於增加如出租國宅、租金補貼、售屋不售地國宅及特殊弱勢團體住宅等國宅產品。

　　There are three main subjects that we want to explore in this study: 1.What problems exist in the public housing waiting system in Taiwan? 2.What reasons cause the demand of public housing much more than the demand of mortgage subsidy in Taiwan? How will we improve it? 3.Is the housing subsidy policy in Taiwan moderate? How will we improve it?

　　To solve the above problems, we first review merits and demerits of the public housing waiting system. We examine three practical functions of the public housing waiting system. One is having the demand of public housing in hand, the one is deciding the order of public housing allocation, and the other one is providing sufficient information to people. From the review, we suggest the directions to improve the public housing waiting system.

　　Second, based on the factors of demand to the public housing (capacity、 willing、 afford ability), we applied regression analysis on the 21-Taiwan-county data. The regression model shows the main factors are the amount of housing allowance and the speed of public housing construction.

　　Finally, with the view of justice and efficiency on the resource allocation of housing subsidy, we simulate the resource distribution of public housing subsidy in the 21-Taiwan-county. We ascertain the main factor of public housing disequilibrium is inappropriate resource allocation. Have we transferred the resource from the public housing for selling to the mortgage subsidy, most counties could solve the disequilibrium problem in short run. In the long run,there are more resources to increase the supply side.These extra-resources serve the public rental housing, rental subsidy and welfare public housing etc..
