環境不確定性增加了企業各種戰略失敗的風險。對員工或求職者而言，環境不確定將導致產業發展前景不明，是否會影響員工對於既有產業的承諾，或潛在求職者的就業選擇，也是值得探討的課題。以大學生為例，大學生因為發展志向或興趣而選擇特定科系就讀，但如果面臨相關產業之環境變化，都可能造成其對於自己在所就讀科系未來出路的不確定，以及前景無法預判等問題，造成對自己的生涯規劃有所遲疑。在此一背景下，本研究擬探討環境不確定知覺對大學生之生涯遲疑之影響，同時也考慮職涯自我效能與心理資本對此一關係的干擾效果。本研究以航運管理學系的大學生作為研究對象進行網路問卷調查，採用信度分析、相關分析、迴歸分析等統計分析方法，以驗證提出之假說。

Environmental uncertainty increases the risk of strategic failure. For employees or job seekers, environmental uncertainty will lead to uncertain industrial development prospects. Whether it will affect employees, commitment to existing industries or potential job seekers, choice of employment and it’s also worth exploring. Take college students as an example. College students choose to study in a specific department due to their aspirations or interests. However, if they are faced with environmental changes in related industries, they may be uncertain about their future career in the department they study and their prospects cannot be predicted, which may lead to hesitation in their career planning. In this context, the purpose of this study was to investigate the effect of environmental uncertainty perception on college students, career indecisive, and moderate the effect of career self-efficacy and psychological capital on this relationship. In this study, college students from the department of Shipping Transportation Management were selected as the subjects for an online questionnaire survey. Reliability analysis, correlation analysis and hierarchical regression analysis were used to verify the proposed hypothesis.
