代际差异视角下粮农保护性耕作投入意愿的影响因素分析
Influencing Factors of Grain Farmers’ Willingness of Arable Land Conservation Input: Based on Perspective of Intergenerational Differences

以豫宁两省(区)797户粮农调查资料为基础，在代际差异视角下，运用Probit模型和Logit模型分析粮农资源禀赋、内在感知对保护性耕作投入意愿的影响。研究表明，新生代和中生代粮农在保护性耕作投入的积极性上高于老一代粮农。资源禀赋和内在感知对粮农保护性耕作投入意愿的影响显著，且存在代际差异。资源禀赋特征下，外出打工和耕地自然质量、年龄、技能培训分别是新生代、中生代和老一代的关键影响因素。共同关键因素中，性别对中生代和老生代粮农的保护性耕作投入意愿具有程度相近的正向影响，而对新生代粮农的影响为负；耕地块数对中生代粮农和老一代粮农具有程度相近但方向相反的影响。内在感知特征下，耕地保护重要性认知变量对中生代影响显著；耕地保护政策认知变量对中生代和老一代影响显著，且对中生代影响程度较大；耕地保护责任人认知变量对新生代和老一代影响显著，且对新生代影响程度较大。
Using a set of survey data from 797 grain farmers in Henan and Ningxia provinces, this paper analyzes the impact of grain farmers’ resource endowments and inner perception on the input willingness of conservation tillage from the perspective of intergenerational differences with Probit model and Logit model. Findings are that the enthusiasm of the new generation and the Mesozoic grain farmers in the arable land conservation is higher than that of the older generation. Resource endowments and inner perception have significant effects on their input willingness of conservation tillage, and there are intergenerational differences in the effects. The factors of going out for work and the quality of arable land, age and skill training, which belong to resource endowments, are the key influencing factors of the new generation, the Mesozoic and the older generation respectively. Among the common key factors, the gender has a similar positive impact on the input willingness of conservation tillage of the Mesozoic and older generation farmers, while the impact of that on the new generation is negative. The impact of cultivated land blocks number on the input willingness of conservation tillage of the Mesozoic and the older generation is in the opposite direction. The importance cognition of cultivated land protection has a significant effect on the Mesozoic. The policy cognition of cultivated land protection has more great and significant influence on Mesozoic than older generation. The cognition of the person responsible for the cultivated land conservation has more great and significant effect on the new generation than the older generation.
