有機農業的發展可以說是一種反工業化的產物，崇尚自然、生態平衡及土地的永續發展，著眼於環境保護和飲食風險上。台灣隨著教育制度的完善和普及，以及經濟的繁榮，人們對於自身身體健康和環境保護的態度、價值觀已有所改變，而反映在食材的購買上，且其中以蔬菜、水果為人們最常買的有機農產品。
促使人們願意付出更高的花費購買有機蔬果，這背後的因素為何，是本研究所要探討的。雖然影響人們購買有機蔬果的原因複雜且多樣，但可以從一些較大的方向找出共通點。本文將會從三個層面探討致使人們購買有機蔬果的原因，分別是經濟資本、文化資本、機會結構，從而推論出是否影響購買有機蔬果的行為，這三個層面分別代表的是家庭收入多寡、教育程度高低、有機專賣店密集度高低，並以布迪厄(Pierre Bourdieu)的實踐理論來分析研究結果。
目前針對有機蔬果消費因素的研究中，皆是針對區域性的研究，尚無針對全台灣的有機蔬果消費行為研究。因此，本研究將會以台灣社會變遷基本調查在2010年對全國進行的調查資料，作為研究資料來源，並使用多元線性迴歸分析等研究方法，探討影響有機蔬果消費的因素。

The development of organic agriculture is often regarded as a product of anti-industrialization, which advocates natural, ecological balance and sustainable development of land, and focuses on environmental protection and dietary risk. The rapid growth of organic food market reflects people’s increasing concerns about the impact of industrialization on individual health and environment.
Although organic food products usually cost more, the consumption of organic vegetables, fruits, and other food categories has been growing exponantially. This observation raises important questions: why are people willing to pay a higher price for organic food products? And who is buying organic vegetables and fruits?
To address the questions indicated above, this study examines the factors that affect the purchase of organic vegetables and fruits in Taiwan. Building on the theory of Bourdieu, this study aims to test the effects of individuals’ economic capital, cultural capital, and opportunity structure on the purchase frequency of organic vegetables and fruits.
Given that previous research on Taiwanese household consumption of organic food products is limited to regional studies, this study contributes to a better understanding of consumption of organic food in Taiwan with the nationwide data from the 2010 Taiwan Social Survey.
