数字经济、财政纵向失衡与农村经济高质量发展——基于黄河流域视角

从经济、创新、协调、绿色、开放、共享6个维度构建黄河流域农村经济高质量发展评价指标体系.分别利用纵横向拉开档次法与熵权法对黄河流域农村经济高质量发展和数字经济进行测度。构建面板门限回归模型，讨论在财政纵向失衡的干预下，数字经济对黄河流域农村经济高质量发展水平的影响。研究发现，财政纵向失衡存在显著单门槛效应，数字经济对农村经济高质量发展水平有显著正向作用，当数字经济突破一定临界值时，其对农村经济高质量发展水平正向作用将会增大。基于此，提出相应政策建议。

Digital Economy, Vertical Imbalance of Finance, and High Quality Development of Rural Economy： Based on the Perspective of the Yellow River Basin

A high-quality development evaluation index system for rural economy in the Yellow River Basin is constructed from six dimensions: economy, innovation, coordination, green, openness, and sharing. The vertical and horizontal leveling method and entropy weight method are used to measure the high-quality development of rural economy and digital economy in the Yellow River Basin. A panel threshold regression model is constructed to discuss the impact of digital economy on the high-quality development level of rural economy in the Yellow River Basin under the intervention of fiscal vertical imbalance.It is found that there is a significant single threshold effect of fiscal vertical imbalance, and the digital economy has a significant positive effect on the high-quality development level of rural economy. When the digital economy breaks through a certain critical value, its positive effect on the high-quality development level of rural economy will increase. Based on this, corresponding policy recommendations are proposed.
