【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 is of great significance to the successful implementation of the strategy of "storing grain in land" in China. In order to reveal the decision-making mechanism of conservation tillage technology used by new agricultural operators, the dual Logit model was adopted in this study. Based on the "100 villages 1000 households" survey data. The effect of technology demonstration on the behavior decision of conservation tillage technology for new agricultural operators was analyzed. The results showed that for large grain farmers, the risk expectation could be reduced by technology demonstration. Increasing the expected income will increase the probability of large grain farmers adopting conservation tillage technology. This study changes the model. The methods and samples also show that the conclusion is robust. The policy revelation is that the extension of the technology demonstration households plays a significant role in promoting conservation tillage technology, and it is an important grasp that can be used.

【正文快照】： 随着传统耕作技术对土壤及环境等方面造成的负面影响越来越大[1],政府及学者逐渐开始关注保护性耕作技术。保护性耕作技术与传统技术不同,主要是通过对土壤少耕、免耕,增加秸秆或绿色植物覆盖,采用多样化的轮作体系,达到保护土壤和环境、提高收益的目的[2]。保护性耕作可以通
