数字金融对城市产业结构升级的影响研究

On the impact of digital finance on the upgrading of urban industrial structure

基于数字金融赋能城市产业结构升级视角,利用2011—2020年中国267个地级及以上城市的面板数据,运用双固定面板模型、空间杜宾模型等探究数字金融对城市产业结构升级的影响效应和作用机制。研究发现:整体上数字金融显著促进城市产业结构升级,其中使用深度和覆盖广度影响更大;作用机制分析显示,数字金融可以通过提升区域创新创业水平促进城市产业结构升级,并且金融监管强度可以正向调节其促进作用;空间溢出效应表明数字金融对城市产业结构升级具有正向溢出效应;分样本看,数字金融对中部、东部城市以及二、三线城市产业结构升级的促进作用更大。该研究为城市深化数字金融建设、优化创新创业环境、完善金融监管机制、统筹区域发展、因城制宜制定政策提供了建议参考。

Based on the perspective of digital finance empowering urban industrial structure to advance,this paper,by employing the panel data of 267 cities of prefecture level and above in China from 2011 to 2020,and by using methods such as dual-fixed panel model and spatial Dubin model,explores the effect and mechanism of digital finance on the upgrading of urban industrial structure.The study finds that on the overall scale,digital finance can significantly promote the upgrading of urban industrial structure,among which the depth and coverage of digital finance exert a greater impact.The mechanism analysis shows that digital finance can promote the upgrading of urban industrial structure by improving the level of regional innovation and entrepreneurship,and that the intensity of financial supervision can positively adjust its promoting effect.The spatial spillover effect shows that digital finance has a positive spillover effect on the advancing of urban industrial structure.By sampling,digital finance plays a greater role in promoting the advancing of industrial structure in eastern,central and second-and-third-tier cities.The study provides suggestions and references for cities to deepen the construction of digital finance,optimize the environment for innovation and entrepreneurship,improve the financial supervision mechanism,coordinate regional development,and formulate policies based on urban conditions.
