民以食為天，台灣更是以農立國的社會，在過去農村產業興盛、農民辛勤務農的景象，隨著時代的演變及產業的發展，已不復存在。農業面臨的三農問題日益嚴重──農民所得偏低，生活無以為繼；農村人口結構老化，勞動力流失；農業採慣行農法、生態環境受到破壞，再加上農藥殘留、重金屬超標等食安問題，人民對於日常生活中賴以生存的農產品不信任，農業面臨極大的挑戰。
銀川米是由賴兆炫先生於1996年成立，以有機農業為其宗旨，與農友以產銷班契作的型式，透過網路平台或實體通路進行銷售精裝米。透過契作高價收購農民栽種的有機米，改善農民所得偏低的問題。透過有機農法，完全不使用化學肥料及農藥，讓生態環境不受破壞，土地恢復生息，並且讓農友們身體健康。透過產銷履歷及有機認證，讓消費者們可以買得安心、吃得放心。另外，也透過有機演講及田間體驗，讓消費者更直接認識及接觸有機農業的好。為了回饋家鄉的農村學子，舉辦有機生活營、提倡食農教育及教導有機農業知識，期許他們成為未來的農業菁英。因此，照顧土地、照顧農友、照顧消費者、培育農業菁英，成為了銀川米的核心價值。
本研究以哈佛個案方式進行，藉由個案內容討論農業社會企業、左右開弓商業模式、價值共創、社會影響力等議題。了解農業社會企業如何改善並解決社會問題；如何設計出左右開弓商業模式，並發展出超越利潤的商業模式；如何與農友、消費者及有機通路商共同創造彼此的價值；最後，如何透過發揮農業社會企業的價值主張，對於農業與社會產生深遠的影響力，讓台灣有機農業得以永續經營與發展。

As the saying goes, people view food as the primary need. Especially, Taiwan establishes industries based on agriculture. The scenes of prosperous agriculture have disappeared with the evolution of times, developments of the industry, and commerce. Agriculture is facing the growing problems: farmers have low incomes and maintain their life more difficult; the aging rural population structure and the shortage of the labor; the practice of conventional agriculture causes destruction of the ecological environment, coupled with food safety issues such as pesticide residues and excessive heavy metals. People have no confidence in the agricultural products on which daily life depends. Due to the problem described above, agriculture is facing great challenges.
Yin-Chuan Organic was founded in 1996 by Lai Chao-Hsuan. Yin-Chuan Organic aims at organic agriculture and cooperates with farmers through the contractual farming system by agricultural production and marketing group. After the process and package procedure, they sell vacuum-packed rice by physical and virtual channels. To improve the problem of low income for farmers, they purchase organic rice planted by farmers through high prices. By organic planting methods, chemical fertilizers and pesticides are not used at all, so that the ecological environment is not polluted, the land is restored to life, and make farmers more healthy. To let people feel ease and trust about their food, they apply the traceability system and organic certification. In addition, consumers learn and realize the benefit and domain knowledge of organic agriculture by keynote speech organized by Yin-Chuan Organic. In order to take care of the rural students in their hometown, they organize organic life camps, promote the food and agriculture education, and teach organic agriculture knowledge. Yin-Chuan Organic hope them to become the elite of agriculture in the future. Therefore, taking care of the land, taking care of farmers, taking care of consumers, and educating agricultural elites have become the core values of Yin-Chuan Organic.
The case is adapted Harvard Case Study research method to discuss the following issues: agricultural social enterprise, ambidextrous business model, value co-creation, social impacts, and so forth. First, it’s necessary to know how agricultural social enterprise improve and solve social problems. Second, we learn how agricultural social enterprise designs the ambidextrous business model and develops triple bottom line business model. Third, we explore how Yin-Chuan Organic co-create the values with farmers, consumers, and organic distributors for each other. The final objective is how to exert a social impact on agriculture and society by exerting the value proposition of agricultural social enterprises, and let the agriculture be sustainable and well-developed.
