摘要
在“双碳”约束日益紧迫和经济下行压力加大的现实背景下,数字普惠金融成为城市经济绿色低碳高质量发展的新动能和可持续增长极。使用非径向方向距离函数测算中国2011-2020年273个地级市能源环境效率,实证检验数字普惠金融对能源环境效率的空间效应及其影响机制。研究发现:(1)能源环境效率呈现出正向空间依赖特征,本地区能源环境效率的提高可以对空间关联地区的能源环境效率产生积极影响。(2)数字普惠金融提高了本地区的能源环境效率,且对周边地区的能源环境效率具有显著正向的空间溢出效应。(3)数字普惠金融主要通过推动节能降耗、促进绿色技术创新和优化产业结构三条途径提高能源环境效率,并且数字普惠金融能通过这三条途径同时提高本地区和周边地区的能源环境效率。(4)数字普惠金融对能源环境效率的正向空间溢出效应在使用深度和数字化程度维度、500km范围内、大型城市、非老工业基地和东部城市更加明显。研究结论为中国能源绿色低碳转型的金融服务优化路径提供了科学决策依据。
Under the realistic background of increasingly pressing“double carbon”constraints and increasing downward pressure on the economy,digital financial inclusion has become a new driving force and sustainable growth pole for green,low-carbon and high-quality development of urban economy.Using non-radial directional distance function to construct the energy-environmental efficiency of 273 prefecture-level cities in China from 2011 to 2020,and empirically testing the spatial effect and impact mechanism of digital financial inclusion on energy-environmental efficiency.The results show that:(1)The energy-environmental efficiency presents the characteristics of positive spatial dependence,and the improvement of local energy-environmental efficiency has a positive effect on the energy-environmental efficiency of spatially-correlated regions.(2)Digital financial inclusion improves the local energy-environmental efficiency,and has a significant positive spatial spillover effect on energy-environmental efficiency in surrounding areas.(3)Digital financial inclusion improves the energy-environmental efficiency by promoting energy conservation and consumption reduction,promoting green technology innovation and optimizing industrial structure in both local and surrounding areas.(4)The positive spatial spillover effect of digital financial inclusion on energy-environmental efficiency is more obvious in the dimension of using depth and digital degree,within 500km,large cities,non-old industrial cities and eastern cities.The conclusions provide scientific decision-making basis for the optimizing path of financial services for the green and low-carbon transformation of energy in China.
