過去幾年來，在全球化競爭環境下，企業莫不競相佈署ERP系統以強化企業流程增加競爭力，然而大多數皆以失敗告終；許多研究指出，使用者抗拒為主要的失敗因素之一；因此，本研究透過抽樣調查，並以整合性科技接受模式(UTAUT)來探討ERP系統的使用者行為，此外，本研究另結合一認知構面—信任(Trust)，以增進原始模型之解釋力，並檢視信任與使用者使用意願之關係。
經研究發現，預期績效、預期付出及信任程度對於ERP系統的使用意願有顯著影響，另外發現預期付出對預期績效也有顯著影響效果；因此建議管理者應著重於提升使用者對於ERP系統之預期績效、預期付出及信任的認知感受，以降低使用者抗拒，增進使用意願，如此將有助於企業佈建成功之ERP系統。

In the competitive circumstances for the past few years, firms have adopted ERP systems to enhance their business processes for more competitive advantages; however, most of them did not succeed. Research indicates that one of the main causes of failure is the resistance of users. This thesis discusses the acts of the ERP system users with Unified Theory of Acceptance and Use of Technology (UTAUT) through a sampling survey. In addition, this research enhances the defining ability of the original model integrating the aspect of trust and examines the relation between trust and users’ intention to use ERP systems.
This research finds that Performance Expectancy, Effort Expectancy and Trust have significant influence on the intention to use ERP systems. Besides, Effort Expectancy has a great influence on Performance Expectancy. Therefore, managers are suggested to improve the users’ cognition for Performance Expectancy, Effort Expectancy and Trust of ERP systems to decrease the users’ resistance and increase their intention. This will help firms establish successful ERP systems.
