中文摘要
近年來,隨著食品安全與健康意識提升,有機食品逐漸受到關注。其無農藥、無化肥的生
產方式,不僅符合健康需求,也呼應環保理念。隨著全球市場穩定成長,台灣的有機耕作與驗
證面積亦持續擴大,顯示其產業潛力不容小覷。
本研究以Ajzen(1975)提出的計劃行為理論為基礎,探討消費者對有機食品的態度、主
觀規範、知覺行為控制-價格及通路與購買意圖之間的關係,並納入健康意識作為衡量變數,
進一步分析態度在其中的中介角色。同時,探討不同產品知識的消費者在有機食品購買意圖上
是否存在顯著差異。
本研究以網路問卷發放方式進行樣本收集,並以結構方程式進行資料分析,得出以下三
點實證結論:
一、 在台灣有機食品市場中,主觀規範、知覺行為控制(通路及價格)及健康意識,都顯著
影響消費者對有機食品購買意圖的形成
二、 在台灣有機食品市場中,主觀規範與健康意識影響有機食品購買意圖的過程中,態度確
實扮演關鍵的中介角色。
三、 在台灣有機食品市場中,不同產品知識的消費者對有機食品購買意願的關鍵前因確實存
在顯著差異
英文摘要
In recent years, as food safety and health conscious have increased, organic food has gradually
gained attention. Its production methods, free from pesticides and chemical fertilizers, not only meet
health demands but also align with environmental protection values. With the steady growth of the
global market, Taiwan’s organic farming and certification areas have continued to expand,
demonstrating the strong potential of the organic industry.
This study is based on the Theory of Planned Behavior proposed by Ajzen (1975) and
explores the relationships among consumers’ attitudes, subjective norms, perceived behavioral
control—price and distribution channels—and their purchase intentions toward organic food. Health
consciousness is included as a variable to evaluate its influence, and the mediating role of attitude is
further analyzed.
Additionally, the study examines whether consumers with different levels of product knowledge
show significant differences in their purchase intentions for organic food.
Data were collected through an online questionnaire and analyzed using structural equation
modeling. The following three empirical conclusions were drawn:
1. In Taiwan’s organic food market, subjective norms, perceived behavioral control (price and
distribution channels), and health consciousness all significantly influence the formation of
consumers’ purchase intentions.
2. Attitude plays a crucial mediating role in the influence of subjective norms and health
consciousness on purchase intentions.
3. Significant differences exist in the key antecedents of purchase intentions among consumers
with varying levels of product knowledge in Taiwan’s organic food market.
