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。
Conservation tillage is of great significance to the successful implementation of our strategy of “grain storage in the land”. In order to reveal the decision-making mechanism of the new type of agricultural management using conservation tillage, this study adopted a binary Logit model, based on the “100 villages Thousands of households, ”the research data to large farmers as an example to analyze the technical demonstration of new agricultural management practices conservation tillage technology adoption behavior decision. The results show that: For big grain growers, the demonstration of technology can reduce the risk expectation and increase the expected return, which in turn will increase the probability that large grain growers adopt the technology of conservation tillage. The replacement model, method and sample in this study also show that the conclusion is robust. Policy enlightenment is in the process of promoting conservation tillage technology, technology demonstration households to promote and demonstrate a significant role, is an important starting point can be used.
