摘　　要：研究农户投入生态转型与粮食生产出的主导因素与限制因素对未来农业生产方式绿色化转型有着重要意义。根据农户生产的投入产出机制及投入要素的组合,对于生态转型的观测变量,选择“产出”“资本”“能耗”“生态”四个量化指标,以咸宁四县的116个村1115农户调查数据为基础,构建农户投入生态转型与粮食产出的结构方程模型(SEM),结果表明:(1)农户投入绿色转型的各要素Cronbach’sα系数为0.89,内部一致性检验通过且结构效度较好;(2)修正模型的GFI、AGFI、CFI、NFI均大于0.90,模型拟合指数均达到评判标准;(3)种子、机械化等的合理投入以及种粮补贴都会带来更多的粮食生产,而劳动力的投入则会引起粮食产出的减少;(4)能耗投入对粮食生产表现为促进作用,而资本、生态投入对粮食生产表现为抑制作用,但生态投入通过机械化、水电投入对粮食生产表现为促进作用。据此,提出相关政策建议。The study of the dominant factors and constraints of the ecological transformation of farmers' inputs and food production is important for the green transformation of agricultural production methods in the future.According to the input-output mechanism of farmers' production and the combination of input factors,for the observed variables of ecological transformation,four quantitative indicators of"output","capital","energy consumption" and "ecology" were selected."(1) The Cronbach's alpha coefficient of each element of green transformation of farmers' inputs is 0.89,and the internal consistency test passed and the structural validity was good;(2) the GFI,AGFI,CFI,and NFI of the modified model were all greater than 0.90,and the model fit indices all met the judging criteria;(3)reasonable inputs of seeds,mechanization and subsidies for grain growing would lead to more grain production,while labor inputs would cause a decrease in grain output;(4) energy consumption inputs showed a promoting effect,while capital and ecological inputs show inhibiting effect on food production,but ecological inputs showed promoting effect on food production through mechanization and hydropower inputs.Accordingly,relevant policy recommendations were proposed.
