本研究主要以房屋仲介從業人員為研究對象，探討組織結構、員工工作滿意度直接或間接(透過組織承諾)對於工作績效的影響。以往研究有兩趨向，一起組織結構、員工工作滿意度以組織承諾其中介變項影響工作績效，另一起組織結構、員工工作滿意度直接影響工作績效，而過去文獻之探討較少涉及四者問互動關係之檢定。本文以線性結構模式(structuralequation model'簡稱SEM)探討其間的互動 因果關係。結果顯示，組織結構、工作滿意度對於工作績效、組織承諾具有正向顯著之影響。但是，無法印證組織承諾對於工作績效具有顯著的影響。即實證結果無法得到組織結構、員工工作滿意度對於工作績效的影響具有中介或間接之效果。
