本研究主要探討決策過程中，權力情境與權力結構對決策之影響。分別以實驗設計及問卷調查加以探討，嘗試得到更佳的信度與效度。經由實驗設計之結果，本研究初步驗證「權力結構」對於部門目標達成有顯著之影響，值得進一步探討，在權力部份，高權力者有較高之績效滿意度；但在本位主義方面，本位主義高者，在績效滿意度較低，而本位主義低者較易滿足；在談判方面，正向談判者滿意度較高，而負向談判者滿意度較低。
接著經由大樣本問卷調查，本研究探討整體架構之運作模式，基於「社會系統」概念加以延伸，探討決策過程中權力結構之影響，結果支持「開放社會系統」概念，驗證本研究所提出各項命題，顯示主要命題大多支持。最後本研究以線性結構方程式(LISREL)，驗證整體架構之效度，並探討整體變數間互動，結果顯示整體架構模式良好。

The main focus of this study is to investigate the influence of power conditions and power structure on inter-departmental decision making in an organization. We adopted both experimental design and questionnaire survey to achieve higher credibility and validity. The results of our experimental design showed that power structure has significantly influences on strategic performance. Specifically, The more power the department owned, the better the performance satisfaction it revealed. The more turf oriented the department is, the lower the performance satisfaction it revealed. Finally, the higher positive negotiation pattern the department adopted, the better the performance satisfaction resulted.
The results of the questionnaire survey have shown that the concept of social open system was supported. Based on the interdependence of resources among functional departments, most of our propositions have significantly been supported by empirical data. This study finally used LISREL to validate the validity of our research framework and to investigate the inter-relationships among research variables. The results showed that the general framework fits well.
