國家科學委員會（簡稱國科會）於志願服務法推展下，自2002年開始啟動科學志願服務工程計畫，是我國具原創立意的創新性志願服務，其以跨領域的科學普及與社會關懷為目標；並自2005年開始，設立補助機制與管道，邀請民間單位共同參與志工培育與科學普及服務工作。面對全球資源短缺下，跨部門治理合產以及志願服務促進公民社會發展之重要趨勢，本研究以國科會補助科學志工團隊計畫為探討情境，瞭解國科會與民間非營利組織之資源交換下，其形構之政策網絡與服務內涵，以檢視補助機制是否回應非營利組織需求。 本研究主要採取深度訪談法、次級資料分析法、參與觀察法，應用鉅觀之Marsh & Smith政策網絡辨證途徑模型非營利組織觀點修正架構，嘗試釐清該補助機制之運作與困境。研究發現科學志願服務乃回應志願服務法規，透過層級委辦與補助途徑，跨部門輸出科學知識轉譯、科學知識建構之服務，交構科學志工之公民知識權內涵。而承辦之國家高速網路與計算中心應用行動者優勢，發展線上平台，提昇國科會科學志工補助機制效率。對於整體資源配置與運用而言，審查委員背景以及其對於科學性之詮釋、團隊計畫書內容品質、以及財務管核體系等，皆影響非營利組織推展科學志工計畫。此外，在公部門有限資源下，團隊組織展示了其專業力、聯結力、培植力優勢；然而，跨部門之間網絡互動連結性弱，對非營利組織來說，整體機制之政策參與度空間有待拓展。 因此，本研究建議應採取策略聯盟行動，強化網絡緊密性，並藉此提昇服務效益，擴散全民受益。最後，則應回歸政策參與管道之建置，以孕育互為主體之跨部門協力溝通場域。 / With “The Volunteer Service Act”, National Science Council (NSC) has developed original Science Volunteer Program since 2002, which is applied to promote the development of science, education and humanities. In order to expand the science volunteer effect, NSC drawn up the subsidy policy in “The NSC Executive Plan for Promoting Science Volunteer”. The subsidy process of Science Volunteer Program practice cross-sectoral partnership between NSC, National Center for High-performance Computing (NCHC), and Non-Profit Organizations (NPOs), and the research takes the perspective of NPOs to examine the subsidy mechanism for Science Volunteer Teams of NSC. Applying the method of in-depth interview, secondary data and participatory observation in the Marsh & Smith Dialectical Approach of policy networks theory, the research finds that science volunteers are both science knowledge interpreters and makers, which devotes to citizen scientists in Taiwan. About the subsidy mechanism and resource dependence, the plan book, reviewers and financial management from NSC affect the development of Science Volunteer Teams. Besides, the network between NSC, NCHC and NPOs is not strong; and policy participation is also expected to improve. Thus, the research suggests that NSC could modify the interactive manner and take strategic alliance to enhance the beneficial result of interdisciplinary collaborative from different excellent NPOs.
