有機農業不僅可產出自然安全的農產品，同時亦得創造優質的農業環境，提供環境公共財與社會公共財，然而這樣的公共財，難以由單一農民提供，而是必須透過同一地區的農民以及利益相關者的共同參與，展開集體行動，才得以有效供給。 宜蘭縣三星鄉行健村是個特殊的案例，有部分農民為推行有機農業，乃成立全台灣第一個由農友組成的有機生產合作社，展開揚棄慣行農法的集體行動，藉由社員互信互助，實踐不施農藥、化肥的栽培，成效初具。然而，行健有機村的知名度雖逐漸提升，但實際上，有機村的名號與實際發展似乎不相襯，目前村內有機耕作面積只佔全村耕作面積的五分之一。因此，本研究以集體行動之理論分析框架，檢視行健村以集體行動促進有機農業發展之可能性。並以文獻分析法、深度訪談法、斷面步行法探究行健村有機農業發展之困境，分析檢討目前的集體行動社會網絡互動模式有何不足之處，期能提供改善建議，以促進該村有機農業發展的可能性。 研究結果顯示該村有機農業發展確實需要集體行動，始能獲致生產及非生產性的共同利益，然而村內網絡間的社會資本不足，以致欠缺發展有機村的共同目標，推展有機農業的集體行動難以擴大，再加上網絡間整合不佳，導致外部資源的投入未有相對應的成效，復又，行健合作社的制度安排不佳，導致營運困境，影響有機村的推展。而中央與地方政府合作不佳，以及現行政府的有機政策導向都關鍵地影響慣性農民轉型有機農業之意願。 本研究認為應增加村內社會網絡間彼此溝通交流之頻度，且行健合作社應重新檢討內部的制度安排，以利促進眾人一心發展有機村之集體行動；而政府方面，應設法改善有機農民之通路、建立有機專區的誘因機制，並且思考補貼政策的轉型，輔以加強消費者食農教育，使有機農業的供需市場擴大並產生互利的良性循環，如此方能讓更多農民願意投入有機耕作，或能真正發展成為兼具生產、生活、生態的「有機村」。 / Organic agriculture not only produces healthy and natural food, but also co-produces environmental public goods and social public goods. However, this kind of goods need to be provided efficiently only by farmers cooperatively, rather than individual. This case study is located in Xingjian village, Sansing Township, Yilan County, where some farmers set up “Xingjian Organic Production Cooperative” to stimulate organic farming development in the village. In this Cooperative, they trust and help each other, trying to persuade other farmers out of using chemical fertilizers and pesticide in farming, and further more, expanding the collective action. To date, some people have been participating in this collective action, as a result, have tackled local agri-environmental issues and provided agri-environmental public goods to some degree. However, as the growing reputation of “Xingjian Organic Village”, the organic farming area only accounts for 20 percent of the total arable land. Therefore, this research using collective action theoretical framework to view the possibility of the Xingjian in promoting organic farming development. This research adopts three ways- literature, in-depth interviews, transect walks, to explore the obstacle of Xingjian village in promoting organic farming development, and to analysis the problem of social network interaction. The result shows that organic agriculture development in the village do need collective action to attain production and non-production of common interests. However, the collective action of organic farming is difficult to expand due to lack of social capital in the village between the networks, and the lack of the common goal in this village. Thus, the input of external resources do not correspond to its performance. Further, institutional arrangements in Xingjian cooperatives functions poor, leading to its operational difficulties. Besides, poor Cooperation between central and local government, as well as the current policy orientation of government, both play a crucial role in affecting farmers' willingness to change conventional farming to organic farming. This study suggests that social networks between the village should connect closely by communicate with each other frequently, and Xingjian cooperatives should review its institutional arrangements, in order to facilitate the collective action of “Xingjian Organic Village”; and the government should try to improve organic produce’s access to market, establish incentives about organic agriculture zone, transfer subsidies policy to organic agriculture, and strengthen consumer’s organic education, so can make more farmers willing to invest in organic farming, or can really develop a production, life and ecology combined "organic village".
