中文摘要 | 本文利用考慮異質變異性的隨機生產邊界模型,同時估算1998-2004 期間稻作農家的生產風險與技術效率,並分析其影響因素。近年來,臺灣的稻米生產是自有勞動節省、耕作機械化、多用肥料、和租地化的型態。實證結果顯示:勞動密集度、機耕工時比率、和租地比率的提高,可以增進技術效率。此外,勞動和肥料是屬於風險遞減型的投入,而土地則是風險遞增型的投入;氣温的高低會影響生產風險,降雨量則没有顯著的影響。最後,根據迴歸結果得知:2001-2004 期間的稻農技術效率低於19982000 期間,而生產風險則是較高的。 |
英文摘要 | The paper estimated the technical efficiency index of Taiwan rice farmers using panel data and a stochastic production frontier with heteroscedasticity during the period 1998-2004. The empirical results show that there were trends of own-labor-saving, mechanization of operations, fertilizer-using, and farm size expansion by lease. A higher level in labor intensity, the ratio of mechanical labor, or the ratio of rented land would yield a higher technical efficiency. Labor and fertilizer were risk-decreasing inputs while land was the risk-increasing input. Moreover, production risk was affected by temperature but not by precipitation. Finally, according to the regression results, the technical efficiency during 2001-2004 was lower than that during 1998-2000 while the production risk of the former was higher than the latter. |
