农户耕地质量保护行为的收入效应研究——基于江西省农户调查数据

Study of the Income Effect of Farmers’Cultivated Land Quality Protection Behavior Based on Rural Household Survey Data in Jiangxi Province

研究目的:基于江西省“双百双千”农户调查数据,探究农户耕地质量保护行为对农业收入的影响及差异。研究方法:内生转换模型、分位数回归模型。研究结果:(1)与未参与耕地质量保护行为的农户相比,参与耕地质量保护行为对农业收入的提升具有显著促进作用。(2)农户耕地质量保护行为对不同农业收入水平的影响表现出一定差异。耕地质量保护行为对较低收入农户的增收作用不明显,对于中等收入农户的增收效应高于较高收入农户。资本投入型和劳动投入型耕地质量保护行为对农业收入的显著性方向与总体行为基本一致。(3)保险投保、高标准农田、生态认知对农户耕地质量保护行为有正向促进作用。研究结论:农户耕地质量保护行为具有显著的增收效应,但对不同农业收入的增收作用呈现显著差异性。据此,应加大对不同收入农户差异化的耕地保护推广力度,积极完善农业基础设施建设和农业保险制度,重点推进农业规模化经营,提升农户生态认知,进而激励农户持续开展耕地质量保护。

The purposes of this study are to understand farmer’s protection behavior towards cultivated land quality,to ensure food security and to promote farmers’income,by analyzing the impacts and differences of cultivated land quality protection behavior on agricultural income based on the survey data of 2,160 farmers in Jiangxi Province.The research methods include endogenous transformation model and quantile regression model.The results showed that:1)compared to farmers who did not participate in cultivated land quality protection,participation in cultivated land quality protection significantly induced higher agricultural income.2)Farmers exhibited some differences concerning the impact of cultivated land quality protection behavior in different levels of agricultural income.Cultivated land quality protection behavior had an insignificant income-enhancing effect on the low-income farmers,while the income-enhancing effect was stronger for the middle-income farmers than for the high-income farmers.The significant direction of capital input type and labor input type for cultivated land quality protection behavior towards agricultural income was basically consistent with the effect direction of overall cultivated land quality protection behaviors towards agricultural income.3)Insurance coverage,high standard farmland construction and ecological cognition positively promoted farmers’cultivated land quality protection behavior.In conclusion,farmers’cultivated land quality protection behavior has a significant income increase effect,but the income-enhancing effect on different agricultural income shows prominent differences.Accordingly,it is necessary to promote the differentiated cultivated land protection of farmers with different income levels,to actively improve the construction of agricultural infrastructure and agricultural insurance system,to focus on facilitating large-scale agricultural operation,and to improve farmers’ecological cognition,with the purpose of encouraging farmers to continuously protect the quality of cultivated land.
