湖南不同季别水稻生产效益研究

Production Efficiency of Different-Season Rice in Hunan

基于湖南农村固定观察点数据,对2005~2013年全省不同季别水稻生产效益进行了研究。结果表明,早稻、中稻和晚稻纯收益分别呈下降、基本稳定和上升趋势。晚稻、中稻纯收益极显著高于早稻。提高纯收益的主攻方向早稻、晚稻是通过提高价格增加主产品产值,中稻是降低物质费用。不同季别水稻生产成本纯收益率均呈下降趋势。中稻、晚稻成本纯收益率极显著高于早稻。提高劳动生产率主攻方向早稻是增加纯收益,中稻、晚稻则是降低生产成本。

The data of rural sited observation were used in this study to test the production efficiency of rice in different seasons in Hunan from 2005 to 2013. The results show that the net income of early-season rice, mid-season rice and late-season rice was decreasing, basically stable and rising, respectively; the net income of late-season rice and mid-season rice was significantly higher than that of early- season rice, respectively; and the increase in net income of early-season rice and late-season rice depended mainly on the increase in the output value of main products by increasing the price, and that of mid-season rice, by reducing the material cost. And the cost net income rate of rice production in different seasons was decreased; the cost net income rate of mid-season rice and late-season rice was significantly higher than that of early-season rice, respectively; and the increase in the early-season rice productivity depended mainly on increasing net income, and those of mid-season rice and late-season rice, on reducing production costs.
