台湾農業の構造調整の遅れの原因の1つとされるのが，小規模農家が資産保有目的で農地の所有権を手放さずに営農を続けるという行動である．本論は台湾の農地の利用規制を検討した上，農地の転用収入の試算とヘドニック法による農業用途の農地価格の形成要因の分析を行った．推計結果から台湾における1992年から2003年までの農地転用収入は農作物の生産額の0.5～1.5倍の規模で発生していることが明らかになった．また，2008年からの2年間の農地取引価格の形成要因を分析した結果，農業収益だけでなくゾーニングの転用規制の程度や人口密度などの農地転用の関連要因も農地価格に大きな影響を与えていることが明らかになった．
Past studies have pointed out that small farmers tend to continue farming for the purpose of keeping the proprietary rights to the farmland as assets, which is one of the reasons holding back the improvement of the agricultural structure in Taiwan. This paper examined farmland regulation in Taiwan and calculated the total revenue by farmland conversion in Taiwan. Then, the determinants of farmland price are estimated by the hedonic approach. From these analyses, it was shown that the total revenue of farmland conversion from 1992 to 2003 in Taiwan was 0.5-1.5 times the revenue from crop production. Furthermore, the analysis of the farmland price in the two years after May 2008 by hedonic approach shows that not only the quality of farmland, which raises the agricultural profit, but also such factors related to farmland conversion as the degree of population density and zoning regulations influence the farmland price.
