| 大豆玉米带状复合种植是优化种植结构和促进农业绿色发展的关键措施,研究其补偿标准对完善多样化种植补贴体系具有重要意义。本文基于农户视角,利用大豆玉米带状复合种植主推区的农户调查数据,采用条件价值评估法和Tobit模型测算和分析了三大主推区大豆玉米带状复合种植的补贴标准。研究结果表明：(1)大豆玉米带状复合种植户的补偿标准整体为212.35元/亩,不同种植区存在差异。西南、西北和黄淮海地区的平均补偿标准分别为175.87元/亩、226.95元/亩和240.94元/亩。(2)基于此标准补贴后,与机会成本对比发现,农户采纳大豆玉米带状复合种植是有利可图的。(3)以大豆种植习惯、经济作物种植习惯和兼业化水平为考量因素的机会成本越低,农户受偿意愿越弱。据此,本文建议政府制定稳定持久的复合种植补贴政策；在制定补贴标准时,各地政府应统筹考虑当地农户的种植习惯与兼业化水平,增强补贴精准度。 |

| Abstract: |
| Maize-soybean relay strip intercropping is an important measure to optimize the planting structure and promote the green development of agriculture, and the study of its subsidy standard is of great significance to improve the subsidy system of strip planting. Based on the perspective of farmers, this paper measures and analyzes the subsidy standards of Maize-soybean relay strip intercropping in the three main promotion areas by using the survey data of farmers in the main promotion areas of Maize-soybean relay strip intercropping, using the conditional value assessment method and the Tobit model. The results of the study show that: (1) The compensation standard for Maize-soybean relay strip intercropping households as a whole is RMB 212.35/mu, with differences in different planting areas. The average compensation standards in southwest, northwest and Huanghuaihai regions are 175.87 yuan/mu, 226.95 yuan/mu and 240.94 yuan/mu, respectively. (2) After the subsidy based on this standard, the comparison with the opportunity cost shows that it is profitable for farmers to adopt soybean-corn banded composite planting. (3) The lower the opportunity cost considering soybean planting habit, cash crop planting habit and parthenogenesis level, the weaker the willingness of farmers to be compensated. Therefore, this paper suggests that the government should formulate a stable and permanent subsidy policy for Maize-soybean relay strip intercropping; when formulating the subsidy standard, local governments should take into account the planting habits of local farmers and the level of part-time employment, so as to improve the accuracy of the subsidy. |
