【摘要】：借鉴MA分析思路,构建农户生产行为环境影响机制的分析框架,并在此框架下构建计量经济模型,以河南省传统农区农户调研数据为基础,选择合适的指标,定量分析农户生产对农业环境影响的大小和方向。主要研究结论如下:(1)农户行为主要是通过农户农业生产投入行为、生计方式、种植结构和规模等方面的传导,通过改变或影响生态环境直接因子对农业环境的变化产生影响;(2)实证结果表明,农户家庭特征(户主年龄、文化程度和劳动力数量)、农户生计方式、种植结构、农户生产规模、细碎化程度和农产品商品化对农业环境影响显著。其中,农户生计方式兼业化加大了农户行为对农业环境的负面影响;农户增收行为,比如种植结构调整和农产品商品化增加了农户行为对农业环境的负面影响,是一种不可持续的农业发展模式;农地经营规模扩大能够对农业环境产生正面影响,但现实中普遍存在的小规模化经营和土地细碎化抵消了正面影响;农产品商品化进一步加剧了农户生产行为对农业环境的负面影响。
[Abstract]:Using MA analysis method for reference, this paper constructs an analytical framework of the environmental impact mechanism of farmers' production behavior, and constructs an econometric model under this framework. Based on the survey data of farmers in traditional agricultural areas of Henan Province, the appropriate indicators are selected. Quantitative analysis of the impact of farmers' production on the agricultural environment and direction. The main conclusions are as follows: (1) Farmers' behavior is mainly through the transmission of farmers' agricultural production input behavior, livelihood mode, planting structure and scale, etc. (2) the empirical results show that the household characteristics (age of head of household, education level and quantity of labor force), farmers' livelihood mode, planting structure, scale of farmers' production, and so on, are affected by changing or influencing the direct factors of ecological environment. The degree of fineness and the commercialization of agricultural products have a significant impact on the agricultural environment. Among them, the combination of farmers' livelihood means increases the negative impact of farmers' behavior on the agricultural environment, and the behavior of increasing farmers' income, such as the adjustment of planting structure and the commercialization of agricultural products, increases the negative impact of farmers' behavior on the agricultural environment. The expansion of agricultural land management scale can have a positive impact on the agricultural environment, but the widespread small-scale operation and land fragmentation in reality offset the positive impact. The commercialization of agricultural products further intensifies the negative impact of farmers' production behavior on the agricultural environment.
