組織知識因其所產生的工作能力效益的不同，可以分成知識基礎能力及知識程序能力二項構面，促進組織知識對組織效能的提升，則會因為組織的工作任務性質，而產生不同程度的影響，依據組織知識所應用的任務環境，亦可以分成「任務導向」特性（集中性及廣泛性）與「任務範疇」特性（內容及程序）二項構面，本研究主要探討在特定組織任務情境下，組織知識能力對組織效能之影響；本研究以三家不同產業性質的大型且知識密集化程度相當高，實施知識管理頗具成效的企業員工為對象，總計148 份問卷為主要樣本，經由徑向分析及層級迴歸等方法進行檢定，發現：1.任務特性確實影響組織知識能力；2.組織知識能力與組織效能有顯著正相關。但文化能力與組織效能之間存在著負相關，而社會化能力與組織效能問則無顯著相關；3.任務特性並未在組織知識能力與組織效能之間造成干擾效果，因為企業均具備良善的知識基礎能力，以致於受到任務特性不同的影響較不明顯。

　　This study primarily explores the moderate effect of organizational knowledge capability on organizational effectiveness under specific organizational task scenarios. Due to the fact that organizational knowledge produces various working ability, it can be divided into two dimensions: fundamental knowledge capability and procedural knowledge capability. The level of improvement that organizational knowledge has on organizational effectiveness will vary due to the different nature within organizations' task. In addition, the task environment utilized by organizational knowledge can also be divided into two dimensions of r task orientation J (collective knowledge vs extensive knowledge) and r task scope J (content guidance vs procedure guidance). The sampling subject will consist of personnels from selected departments of three large enterprises, which are different in nature and have a high level collection of knowledge while effectively executing knowledge management. There are 148 questionnaires in our main sample, assessed by statistical methods of path analysis and hierarchical regression analysis. Research shows: l. Task characteristic can affect organizational knowledge capability; 2.There exists a positive correlation between organizational knowledge capability andorganizational effectiveness. On the other hand, there is a negative correlation between cultural ability and organization effectiveness, and there is no obvious correlation between socialization capability and organization effectiveness; 3.Task characteristic does not have moderate impact on organizational knowledge capability and organizational effectiveness because the enterprises all exhibit proficient fundamental knowledge capability such that the various effects caused by task characteristic are less apparent.
