摘要: 以长三角为研究样本,从理论与实证两个方面检验数字金融对高质量发展的空间效应及影响机制。研究发现:(1)数字金融对本地及邻地高质量发展具有促进作用,并存在维度异质性、时间异质性和空间异质性特征。在维度异质性方面,数字金融覆盖广度、使用深度对本地及邻地高质量发展的影响显著为正,而数字化程度的本地及邻地高质量发展效应则显著为负;在时间异质性方面,数字金融对本地及邻地高质量发展的长期影响大于短期,表明数字金融的网络效应和“梅特卡夫法则”在高质量发展体系中显著成立;在空间异质性方面,数字金融及其细分维度的空间溢出效应随地理距离增加而逐渐衰减,215 km为有效溢出边界。(2)制造业与生产性服务业协同集聚(以下简称“产业协同集聚”)、地方政府行为(官员更替、财政支出偏向、环境规制)是数字金融影响高质量发展的重要途径,可与数字金融建设形成协同合力。(3)在高质量发展的低值区域及互联网发展的高值区域,数字金融对高质量发展的红利释放更为明显。

Abstract: Taking the Yangtze River Delta as a research area, this paper investigated the spatial effect and influencing mechanism of digital finance on high-quality development from the theoretical and empirical aspects. The findings were as follows: (1) Digital finance could promote the high-quality development of local and neighboring areas, and there were characteristics of dimensional heterogeneity, temporal heterogeneity and spatial heterogeneity. In terms of dimensional heterogeneity, the coverage breadth and use depth of digital finance had a significantly positive effect on local and neighboring high-quality development, while the digitalization degree had a significantly negative effect on local and neighboring high-quality development. In terms of temporal heterogeneity, the long-term impact of digital finance on local and neighboring high-quality development was greater than the short-term impact, indicating that the network effect and “Metcalfe’s law” of digital finance were significantly established in high-quality development system. In terms of spatial heterogeneity, the spatial spillover effect of digital finance and its subdivision dimension gradually decreased with the increase of geographical distance, and 215 km was found to be the effective spillover boundary. (2) The collaborative agglomeration of manufacturing and producer services (hereinafter referred to as “industrial collaborative agglomeration”), local government behavior (official replacement, fiscal expenditure bias, environmental regulation) were the important ways for digital finance to affect high-quality development, and could form collaborative forces with digital finance construction. (3) In the low-value region of high-quality development and the high-value region of Internet development, the dividend release of digital finance on high-quality development was more obvious.
