本研究利用搜尋成本與價格分散的觀點，檢視具有訊息優勢的仲介服務業者是否真能提高住宅市場的訂價與價格搜尋效率。實證結果顯示：第一，成交價價格分散度明顯小於訂價價格分散度；第二，透過仲介服務搜尋者訂價價格分散未顯著異於自行搜尋者的訂價價格分散，而透過仲介服務搜尋者的成交價價格分散則顯著小於自行搜尋者的成交價價格分散，同時價格收斂比率較高。換言之，仲介服務業者可能基於策略行為未能調整適當的訂價，但是能夠利用搜尋密度的提高，有效地降低成交價格的價格分散度。

This article examines whether the information advantage of brokerage services affects the housing market in terms of search cost and price dispersion and actually elevates pricing and price search efficiency. Empirical results indicate that the dispersion of transaction price is lower than that of listed price. Further, the dispersion of listed price with brokerage service is not resembled that of for-sale-by-owner (FSBO), but the dispersion of transaction price with brokerage service was lower than that of FSBO. Restated, for strategic considerations, brokers should not advise sellers to adjust asking prices, but they should decrease the dispersion of transaction prices with high search density.
