    摘要:

    本文基于2023年湖北省的实地调研数据,采用SFA和SBM-DEA模型对不同稻田种养模式的技术效率和生态效率分别进行了测算,旨在探究它们之间的效率差异。研究结果显示:(1)在单稻、“稻-虾”、“稻-鸭”和“稻-虾-鸭”4种稻田种养模式中,“稻-虾-鸭”模式的技术效率和生态效率均表现突出,分别为0.760和0.545;而“稻-鸭”模式的技术效率及“稻-虾”模式的生态效率最低,分别为0.581和0.323。(2)户主性别、农业保险、经济发展水平、极端气温以及平均降雨量等因素抑制了技术效率的提升,而户主年龄、农业补贴、家庭总收入和无人机使用则促进技术效率的提高。(3)户主年龄和高温热浪指标显著提高了生态效率;而户主性别、家庭总人口数、家庭总收入、无人机使用情况、经济发展水平、极端低温和干旱等因素则抑制了生态效率的提升。(4)相比单稻模式,“稻-虾”模式的技术效率和生态效率显著降低0.053和0.178;而“稻-虾-鸭”模式的技术效率比单稻模式高0.163。

    Abstract:

    This study is based on field survey data from Hubei Province in 2023 and employs the SFA and SBM-DEA models to measure the technical efficiency and ecological efficiency of different rice-farming systems, aiming to explore the efficiency differences among them. The results indicate that: (1) Among the four rice-farming modes—single rice, “rice-shrimp”, “rice-duck”, and “rice-shrimp-duck”—the “rice-shrimp-duck” mode demonstrates the highest technical and ecological efficiency, with values of 0.760 and 0.545, respectively. In contrast, the technical efficiency of the “rice-duck” model and the ecological efficiency of the “rice-shrimp” model were the lowest, at 0.581 and 0.323, respectively. (2) Household head's gender, agricultural insurance, economic development level, extreme temperatures, and average rainfall have inhibited the improvement of technical efficiency, while household head age, agricultural subsidies, total household income, and drone usage contribute positively to technical efficiency. (3) The age of the household head and high-temperature heatwave indicators significantly improve ecological efficiency, while factors such as household head gender, total household population, total household income, drone usage, economic development level, extreme low temperatures, and drought negatively affect the improvement of ecological efficiency. (4) Compared to the single rice mode, the rice-shrimp mode's technical efficiency and ecological efficiency decrease significantly by 0.053 and 0.178, respectively, while the rice-shrimp-duck mode's technical efficiency is 0.163 higher than that of the single rice mode.
