| 摘要: |
| 保护性耕作对我国"藏粮于地"战略的顺利实施有重要意义，为了揭示新型农业经营主体采用保护性耕作技术的决策机制，本研究采用二元Logit模型，基于辽宁省"百村千户"的调研数据，以种粮大户为例分析技术示范对新型农业经营主体保护性耕作技术采用行为决策的影响。研究结果表明：对种粮大户而言，通过技术示范可降低其风险预期，提高预期收益，进而会提升种粮大户采用保护性耕作技术采用的概率。本研究更换模型、方法和样本也表明该结论是稳健的。政策启示是在推动保护性耕作技术的过程中，技术示范户的推广、示范有显著的作用，是一个可以利用的重要抓手。 |

| Abstract: |
| Conservation tillage technology has important significance for the smooth implementation of food crop production strategy on farmland management.To reveal the decision-making mechanism of adopting new conservation tillage techniques among new agricultural business operators,large crop-land owners are taken as study object.New agricultural business operators' behavior decision on conservation tillage technology is also analyzed.Using Logit model,the effect of technology demonstration to the behavior decision is verified based on the research data in Liaoning Province.In conclusion,technology demonstration can reduce the famers' expected risk and increase the expected return and enhance probability of the farmers adopting conservation tillage technology.In the process of promoting conservation tillage technology,technology demonstration plays key role. |
