| 【目的】随着优质稻市场需求的提高,科学评估优质稻跟普通稻的种粮效益,对提高农户种粮效益和未来水稻育种方向的选择具有重要意义。【方法】本研究基于广东省水稻种植户2021-2022年的调研数据,运用内生转换模型,对优质稻和普通稻的种粮效益进行评估,并且根据不同种植季节分早晚稻对优质稻和普通稻的种粮效益进行分析。【结果】(1)优质稻的产量比普通稻低,在优质稻地块和普通稻地块上,优质稻产量比普通稻产量分别低10.34%和0.27%。(2)优质稻的成本与普通稻相比没有绝对优势,在优质稻地块和普通稻地块上,优质稻成本比普通稻成本分别增加0.93%和减少7.62%。(3)优质稻净收益高于普通稻,在优质稻地块和普通稻地块上,优质稻净收益比普通稻净收益分别增加4.69%和45.44%。【结论】在水稻生产日益受市场因素影响的背景下,优质稻的面积呈现总体扩展趋势,在一定程度上改善了水稻效益,但也可能会带来粮食产量降低的风险。优质与适度高产兼顾应是未来水稻育种的重要方向。 |

| 【Objective】With the increasing demand for high-quality rice in the market,scientifically evaluating of the grain planting benefits of high-quality rice and ordinary-quality rice is of vital significance for increase farmers income and steering future directions in rice breeding.【Method】Based on a survey data from rice farmers in Guangdong Province for the years 2021-2022,this paper uses the Endogenous Switching Regression model to evaluate the yield,cost and benefits associated with high-quality and ordinary-quality rice,Furthermore,it conducts an analysis of the grain planting benefits with respect to different cultivation season.【Result】(1)The yield of high-quality rice is lower than that of ordinary-quality rice. In high-quality rice fields and ordinary-quality rice fields, the yield of high-quality rice is 10.34% and 0.27% lower than that of ordinary-quality rice, respectively.(2)The cost of high-quality rice does not have an absolute advantage compared to ordinary-quality rice.In high-quality rice fields and ordinary-quality rice fields, the cost of high-quality rice increased by 0.93% and decreased by 7.62% compared to ordinary-quality rice, respectively.(3)The net profits of high-quality rice is higher than that of ordinary-quality rice. In high-quality rice fields and ordinary-quality rice fields,the net profits of high-quality rice is increase 4.69% and 45.44%, respectively.【Conclusion】Against the backdrop of rice production increasingly influenced by market factors, the area dedicated to high-quality rice is showing an overall expansion trend, which to some extent improves the profitability of rice cultivation but may also introduce the risk of reduced grain output.Balancing quality with moderate high yields should be an important direction for future rice breeding. |
