    摘要:

    [目的] 探索数字经济赋能农业生态产品价值转化,为建设数字乡村和促进农民增收提供理论依据。[方法] 通过功能价值法核算农业生态产品的生态价值,利用超效率SBM模型测算长江经济带99个城市2012—2022年农业生态产品价值转化效率,运用核密度分析价值转化效率的变化趋势,用双向固定效应模型探究数字经济对农业生态产品价值转化效率的影响机制,进一步利用空间杜宾模型检验数字经济对长江经济带农业生态产品价值转化效率是否存在空间溢出效应。[结果] ①长江经济带农业生态产品价值转化效率呈上升趋势,存在轻微两极分化现象;②数字经济显著提升农业生态产品价值转化效率;③数字经济通过促进绿色技术创新和绿色金融提升农业生态产品价值转化效率;在长江经济带下游和资源型城市,数字经济更有助于促进农业生态产品价值转化效率提升。④数字经济对农业生态产品价值转化效率存在明显的空间溢出效应。[结论] 数字经济对农业生态产品价值转化效率有显著的促进作用,存在中介效应、异质性特征和空间溢出效应,在促进农业生态产品价值转化时应予以充分考虑。

    Abstract:

    [Objective] The value conversion of agricultural ecological products empowered by the digital economy was explored in order to provide a theoretical basis for building digital villages and increasing farmers' income. [Methods] The ecological value of agricultural ecological products was calculated using the functional value method, and the value conversion efficiency of agricultural ecological products in 99 cities along the Yangtze River economic belt from 2012 to 2022 was measured using the super-efficiency SBM model. The variation trend of value conversion efficiency was analyzed through kernel density analysis. The impact mechanisms of the digital economy on the value conversion efficiency of agricultural ecological products were explored using the two-way fixed effects model. Furthermore, the spatial Durbin model was used to test whether there were spatial spillover effects of the digital economy on the value conversion efficiency of agricultural ecological products in the Yangtze River economic belt. [Results] ① The value conversion efficiency of agricultural ecological products in the Yangtze River economic belt showed an upward trend, with slight polarization observed.② The digital economy significantly enhanced the value conversion efficiency of agricultural ecological products.③ The digital economy improved the efficiency by promoting green technology innovation and green finance. Heterogeneity analysis indicated that in the lower reaches of the Yangtze River economic belt and in resource-based cities, the digital economy was more conducive to improving the efficiency of agricultural ecological product value conversion.④ The digital economy had a significant spatial spillover effect on the value conversion efficiency of agricultural ecological products. [Conclusion] The digital economy significantly promotes the value conversion efficiency of agricultural ecological products, exhibiting mediation effects, heterogeneity, and spatial spillover effects, which should be fully considered when promoting the conversion of agricultural ecological product value.
