在社会经济高速发展、追求绿色低碳农业的背景下,提高耕地碳生产率是实现社会经济可持续发展的有效的途径.研究基于 2020 年湖南省常德市农户调研数据,运用Tobit模型实证检验了农户分化对耕地碳生产率的影响.研究结果表明:在表征农民分化特征的两个变量中,农户职业分化程度对耕地碳生产率有显著的负向影响,且收入分化强化了职业分化对偏非农型农户耕地碳生产率的负向影响效应;收入分化对耕地碳生产率的影响效应受到农户职业分化程度的制约,收入分化对偏农型农户耕地碳生产率有正向影响,职业分化强化了收入分化对偏农型农户耕地碳生产率的正向影响效应;职业分化削弱了收入分化对偏非农型农户耕地碳生产率的影响效应;此外,在其他控制变量中,受教育程度和集镇距离对耕地碳生产率也存在显著的正向影响.
Impact of Farmers'Differentiation on Carbon Productivity of Farmland:A Case Study of Changde City
Against backdrops of the high-quality social development and the pursuit of green and low-carbon agriculture,based on the 2020 survey data of farmers in Changde city,Hunan province,the Tobit model was used to empirically test the impact of farmers'differentiation on the carbon productivity of farmland.The research results indicate that among the two variables characterizing the differentiation characteristics of farmers,the degree of occu-pational differentiation of farmers has a significant negative impact on the carbon productivity of farmland,and the income differentiation strengthens the negative impact of occupational differentiation on the carbon productivity of farmland for non-agricultural oriented farmers.The impact of income differentiation on the carbon productivity of farmland is constrained by the degree of occupational differentiation among farmers.The income differentiation has a positive impact on the carbon productivity of farmland for agricultural oriented farmers,and the occupational differ-entiation strengthens the positive impact of income differentiation on the carbon productivity of farmland for agricul-tural oriented farmers.The occupational differentiation weakens the impact of income differentiation on the carbon productivity of farmland for non-agricultural oriented farmers.In addition,among other control variables,the educa-tion level and town distance also have significant positive impacts on the carbon productivity of farmland.
