The situation of ageing population in Taiwan is getting serious, especially in agricultural sector. Many researchers suggested that ageing farmers could have negative impacts on agricultural production, but few of them could provide promising findings by using quantitative methods. Since labor is one of the key factors affecting the development of agriculture, it is important to realize the age structure of farmers and further analyze its correlation with agricultural labor productivity. For this reason, the purpose of this research is to investigate the age structure of Taiwan’s farmers and to analyze the relationship between farmers’ age and the labor productivity.995 and 2005 census data and regression analysis are used to investigate the age structure and its relationship with labor productivity. The results show that the ageing issue for Taiwan’s agricultural sector is more serious than ever. In 2005, more than 18.61 percent of farmers are older than 65 years old, which is 7.24 percent higher than 10 years before. Moreover, the life cycle effect was found in Taiwan’s agricultural labor productivity, and its peak is between 40 and 50 years old. Our findings also suggest that, in general, male farmers, living in eastern part of Taiwan, or growing mushroom / flowers have higher productivities. Besides, Operating areas are owned most by ageing farmers who have low labor productivities, and the older the farmers are, the more lands they have. The young farmers who have high labor productivities can’t get enough lands to cultivate, so that the whole productivity can’t increase. It’s also the main reason that ageing farmers affect negatively on agriculture.口試委員審定書 i辭 ii文摘要 iii文摘要 iv一章 緒論 1一節 研究動機與目的 1二節 研究方法與流程 2三節 論文架構 3二章 台灣農耕業農民年齡結構與生產力概況 4一節 台灣農耕業農家人口年齡結構 4二節 台灣農耕戶主要生產者年齡結構之分配 9三節 台灣農耕戶主要生產者經營規模與勞動生產力概況 15三章 文獻回顧 49一節 農耕戶勞動力之相關文獻 49二節 農民高齡化及其對農耕業生產與經營影響之相關文獻 57三節 小結 62四章 實證模型與估計結果 63一節 資料來源及處理與模型設定 63二節 估計結果 66五章 高齡化對勞動生產力之影響與政策意涵 73一節 模擬分析 73二節 高齡化之效果分析及政策意涵 75六章 結論與建議 84一節 結論 84二節 建議 86考文獻 88application/pdf590051 bytesapplication/pdfen-US高齡化農耕業勞動生產力經營面積農民年齡分配生命週期AgeingAgricultural labor productivityOperative areaFarmer’s age distributionLife cycle[SDGs]SDG2thesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/182379/1/ntu-98-R96627025-1.pdf
