摘要： 数字金融已经成为破解金融排斥困境的核心途径,是助推服务业转型升级的重要抓手。已有文献对数字金融发展的经济效应进行了较为丰富的研究,但鲜少关注其对服务业转型升级的影响,更加缺乏从空间溢出效应的视角展开深入分析。本文利用中国地级城市面板数据,构建面板空间杜宾模型,实证检验了数字金融发展影响服务业转型升级的本地效应与空间溢出效应,并对空间溢出效应的地理衰减边界进行了测算。研究发现:数字金融发展对服务业转型升级具有正向显著的本地效应和空间溢出效应,既有助于本地区服务业转型升级,也有效带动了周边邻近城市服务业转型升级;更换空间模型、替换空间矩阵以及改变研究样本后的稳健性检验结果印证了上述结论的可靠性;数字金融发展对服务业转型升级的空间溢出效应存在随地理距离持续扩大而逐渐衰减的特征,且当城市间地理距离跨越260公里以后,空间溢出效应将不再显著。

Abstract: Digital finance has become the core way to solve the dilemma of financial exclusion, and is an important starting point to boost the transformation and upgrading of the service industry. Existing literature has conducted rich studies on the economic effect of digital finance development, but little attention has been paid to its impact on the transformation and upgrading of the service industry, and there is a lack of in-depth analysis from the perspective of spatial spillover effect. This paper selects the panel data of prefecture-level cities in China, constructs the panel Spatial Durbin Model, empirically tests the local effect and spatial spillover effect of digital finance development on the transformation and upgrading of the service industry, so measures the geographical attenuation boundary of spatial spillover effect. The results show that digital finance development has significant positive local and spatial spillover effects on the transformation and upgrading of the service industry, which not only contributes to the transformation and upgrading of the service industry in the region, but also effectively drives the transformation and upgrading of the service industry in neighboring cities. The robustness test results after replacing the spatial model, replacing the spatial matrix and changing the research samples confirm the robustness of the above conclusions. The spatial spillover effect of digital finance development on the transformation and upgrading of the service industry decreases with the increase of geographical distance, and when the geographical distance between cities exceeds 260 kilometers, the spatial spillover effect will no longer be significant.

Key words: the transformation and upgrading of service industry, digital finance development, spatial spillover effect, attenuation boundary
