【摘要】：在农地大规模流转背景下,采取保护性耕作技术并增加农户农地投资对于农地质量和粮食安全意义重大。基于黑龙江、河南、浙江和四川4省农户调查数据,以秸秆还田单位面积投资作为保护性耕作投资指标,采用两步法IV-Tobit模型,分析不同农地类型农户对保护性耕作投资的影响,并进一步研究影响农户对转入地投资的因素,从而探讨产权因素在保护性耕作投资决策中的作用。结果表明,样本农户的农地流转面积占比高达86.09%,发生农地流转的农户数占比也高达71.15%。土地流转契约具有以口头形式为主、约定年限短的特点。农户对保护性耕作投资仍处于低水平状态,农户在自有地上的投资略高于在转入地上的投资,多投5.25元/hm2;农户在转入地上进行秸秆还田保护性耕作投资比在自有地上少。此外,契约形式、是否约定年限、户主年龄、农户对政策了解程度、家庭劳动力数目、转出户是否要求土壤肥力保持对农户在转入地上的投资有显著的影响。基于此,提出完善土地流转机制,规范土地流转进程;做好保护性耕作的投资收益评价工作,以便为农户提供精准的农业补贴;做好政策宣传工作,增强农户保护耕地的意识等政策建议。
[Abstract]:Under the background of large-scale agricultural land transfer, it is of great significance to adopt conservation tillage technology and increase farm land investment for agricultural land quality and grain security. Based on the survey data of 4 provinces in Heilongjiang, Henan, Zhejiang and Sichuan, the two step method IV-Tobit model is used to analyze the unit area investment of straw returning as a protective tillage investment index. The influence of farmers on different farmland types on the investment of conservation tillage, and further research on the factors affecting farmers' investment in the transferred land, and then discuss the role of property right factors in the decision-making of conservation tillage investment. The results show that the proportion of the land circulation area of the sample farmers is up to 86.09%, and the proportion of the number of farmers in the farmland circulation is also up to 71.15%. The land transfer contract is characterized by the oral form and the short fixed number of years. The farmers' investment in conservation tillage is still at a low level, and the investment of farmers on their own land is slightly higher than the investment on the transfer to the ground, and 5.25 yuan /hm2 is more invested. The form of contract, the age of the household, the age of the household, the degree of farmers' understanding of the policy, the number of household labor, and whether the transfer of soil fertility to the investment of the farmers in the transfer to the ground is significant. Based on this, the paper proposes to improve the mechanism of land transfer, standardize the process of land transfer, and do a good job of evaluating the investment income of conservation tillage. In order to provide farmers with accurate agricultural subsidies, do policy propaganda work and enhance farmers' awareness of farmland protection.
