本文基于山西、河北、天津、北京四个省份调研样本的基础上,对保护性耕作技术体系中的秸秆还田和免耕播种两项技术农户采纳情况分别构建logit模型,定量分析农户采纳这两项技术的主要影响因素。分析结果表明,农户对两项技术的采纳倾向都受到政府的强制或补贴措施、粮食商品化程度、户主身体健康状况三个因素的正向影响。此外,秸秆还田技术的采纳还受到秸秆是否有经济用途、农户劳均土地块数两个因素的负向影响;免耕播种技术的采纳还受到家庭人均受教育程度、户主年龄、农户对免耕播种技术的评价三个因素的正向影响。
Based on the research samples from four provinces of Shanxi, Hebei, Tianjin and Beijing, this paper constructs the logit model for the adoption of two technologies of straw mowing and no-tillage sowing in the system of conservation tillage technology, and quantitatively analyzes the adoption of these two The main factors affecting the technology. The results of the analysis show that the tenants’ preference for adopting both technologies is positively influenced by the government’s coercive or subsidized measures, the degree of food commercialization, and the health status of household heads. In addition, the adoption of straw returning technology is also affected by the economic use of straw, the average number of farmers per head of land is negatively affected by two factors; the adoption of no-till sowing technology is also affected by the per capita family education, head of household age, Evaluation of plowing and sowing technology, the positive impact of three factors.
