摘要

甘藷為台灣早期之主要雜糧作物，具更栽培容易、單位陎積產量高和營養豐
富等諸多優點，而近年來，隨著國民所得提高及國人養生概念的提升，甘藷的利
用已轉換為以消費導向為主。
本研究透過深度訪談，蒐集資訊與意見，探討與研究台灣甘藷產業的發展，
如甘藷產銷概況、商品的價值與行銷通路等。透過農民、企業在新鮮甘藦及加工
品(包含甘藷皮)的獲利分析，顯示2016 年每公頃甘藷平均收益是355,235 元，農
家賺款是(毛利) 254,266 元，因此，每公頃的毛利率達71.58%。甘藷經加工成夯
番薯後，農企業業每公頃之銷售毛利率59.49%，加工成甘藷酥條的毛利率較低為
47%。甘藷皮經加工後轉化為生技產品毛利率也可達58.6%。
由上述發現，顯示臺灣發展甘藷產業擁更龐大的市場商機，並發現導入生物
技術也是創造台灣甘藷加工副產品利用的重要途徑之一。提升台灣甘藷產業之競
爭力必頇強化技術商品化，建立獨更的通路與品牌行銷，以最大化提昇產品附加
價值，如此一來，才能促進台灣甘藷產業蓬勃發展，並拓展農業的新契機。

Sweet potato is the main grain crops in Taiwan in the early time. It also has many
advantages such as easy cultivation, high yield per hectare area, and rich nutrition. In
recent years, with the income rise and the concept of health promoting, the utilization of
sweet potato has been transformed into consumption oriented.
This study uses in-depth interview to collect information and opinions. To explore
the development of sweet potato industry in Taiwan, production and marketing of sweet
potato, commodity value and marketing channels have been analyzed to estimate the
profitability of farmers and agribusiness enterprises in fresh and processed products
(including sweet potato skins). It was found that the total farm revenue from sweet
potato sales was NT$355,235 per hectare in 2016 with the gross revenue of
NT$254,266, and the gross profit margin of 71.58%. If the sweet potato were
processed by agribusiness enterprises into roasted products, the gross profit margin
would be 59.49%. If the sweet potato were processed into sweet potato fries, the gross
margin would be reduced to 47%. If the sweet potato skins was processed by
biotechnology enterprises into biotech nutrition products, the gross profit margin would
be 58.6%.
To summarise, this study indicates that the development of sweet potato industry
in Taiwan is full of market opportunities. We that the introduction of biotechnology is
an important way to create the new processing and utilization of sweet potato
by-products. To enhance the competitiveness of sweet potato industry in Taiwan, we
must strengthen the commercialization of biotechnology, establish spcilized marketing
channel and brand marketing, as well as maximize the value-added of product lines. In
this way, it can promote the vigorous development of sweet potato industry and bring in
new opportunities for agriculture in Taiwan.
