員工的核心能力為組織績效與競爭力的基礎，早已成為國內外當代學術社群與管理實務者的共識。這是因為無論是公私部門組織，目前均處於極大的績效壓力。而國會聯絡人身為行政部門與立法部門之間的橋樑，法律案及預算案的推手，其核心能力與法案通過的機率、組織的效能及競爭力密切相關。職是之故，本研究擬以核心能力理論為基礎，再藉由相關國內外文獻的整理，對現任國會聯絡人的行為事件訪談以及問卷調查的結果，歸納出優秀國會聯絡人所應具備的核心能力具體項目，以作為機關首長據以選任取才的參考依據。 本研究係以行政院暨所屬部國會聯絡人服務年資超過五年之優秀資深人員為訪談對象，再以問卷、行為事件訪談的交叉方式，探索出國會聯絡人有效推動工作應具備的核心能力，本研究從中發現到：國會聯絡人應具備的核心能力要有「環境變化的洞察力」、「溝通協調」、「團隊合作的精神」、「顧客服務導向」、「政策行銷與說服能力」、「嫻熟議事運作相關法令」、「積極主動」、「情緒管理」等合計8項核心能力，並對行政機關及首長、國會聯絡人、立法委員提出建議。 / Staff’s core competence as the foundation for organizational achievements and competence has already become mutual recognition of the contemporary domestic and foreign academic social groups and the managerial practitioners. Regardless whether it is public or private departmental organization, nowadays they are burdened with enormous pressure of achievements. As the bridge between the administrative department and the legislation department, the advocator of the legal bills and the budget proposal, the core competence of the congressional liaison staff are closely correlated with the probability of the passage of the bills, organizational efficiency, and competitive power. For this reason, this study draws upon the theory of the core competence as the foundation, with review of domestic and foreign literatures, and interview of the behavior events of the incumbent congressional liaison staff as well as by questionnaire surveys. The information thus collected induces the concrete items of core competence which congressional liaison staff should have and be regarded as reference by heads of institutions for staff recruitment. The subjects of this study are senior congressional liaison staff members with five-year tenure at the Executive Yuan and outstanding evaluation. By the questionnaire and the behavior event interview, they were explored for the core competences of congressional liaison staff to impetus their work effectively. This study has discovered that the congressional liaison staff should have core competence including the following eight items, they are “the insight to environmental change”, “the ability of communication and coordination”, “the spirit of the team cooperation”, “the orientation of customer service”, “the ability of policy marketing and persuasion”, “thorough understanding of legislative procedures and the related laws”, “positive initiation”, and “mood management”; and also to put forward their suggestions and recommendations to heads of executive and administrative divisions, other congressional liaison staff members, and legislators.
