    摘要:

    耕地是保障国家粮食安全的基石,探究数字普惠金融影响耕地利用生态效率的空间溢出效应对推进农村金融发展、促进农民增收和高水平耕地保护利用具有重要意义。本研究基于2011—2021年东北黑土区27个地级市面板数据,采用超效率EBM模型测算耕地利用生态效率,利用空间杜宾模型和偏微分分解法揭示数字普惠金融对耕地利用生态效率的影响及其空间溢出效应。研究结果表明:东北黑土区的数字普惠金融发展水平持续提高,而耕地利用生态效率则呈现“W”型变化波动上升,区域间差异显著;数字普惠金融对本地耕地利用生态效率的提升具有直接影响,呈现出“倒U”型的非线性关系,同时对邻地的影响存在空间溢出效应,呈现“U”型的非线性关系;三江平原区和长白山-辽东丘陵区与东北黑土区的数字普惠金融对耕地利用生态效率的影响效应方向一致。基于研究结果,提出了夯实数字普惠金融发展基础、缩小区域数字普惠金融差距、合理规避数字普惠金融虹吸效应等政策建议,以促进数字普惠金融高质量发展与黑土地有效保护协同推进。

    Abstract:

    Cultivated land is crucial for ensuring national food security. It is essential to investigate the spatial spillover effect of digital inclusive finance on the ecological efficiency of cultivated land utilization to promote the development of rural finance, farmers’ income, and the efficient use of cultivated land. This study uses panel data from 27 prefecture-level cities in the Northeastern Black Soil Area from 2011 to 2021, employing the ultra-efficiency EBM model to measure the ecological efficiency of cultivated land utilization. The research reveals the impact of digital inclusive finance on cultivated land utilization and the spatial spillover effect using the spatial Durbin model and partial differential decomposition method. The results show that digital inclusive finance has been steadily improving in the Northeastern Black Soil Area, and the ecological efficiency of cultivated land utilization has increased in a “W” type fluctuation with significant regional differences. Digital inclusive finance directly affects the improvement of local cultivated land utilization, displaying an “inverted U” non-linear relationship. It also has a spatial spillover effect on adjacent land, presenting a “U” non-linear relationship. The relationship between digital inclusive finance and ecological efficiency of cultivated land utilization in the Sanjiang Plain and Changbai Mountain-Liaodong hilly areas is consistent with the effect of the Northeastern Black Soil Area. Based on these findings, policy suggestions are proposed to strengthen the foundation for digital inclusive finance development, narrow the gap in regional digital inclusive finance, and avoid the syphon effect of digital inclusive finance. This will ensure the coordinated promotion of high-quality development of digital inclusive finance and effective protection of black land.
