数字普惠金融驱动经济高质量发展的作用机制研究——以四川省为例

Mechanisms of Digital Inclusive Finance Driving High Quality Economic Development Research—Taking Sichuan Province as an Example

摘要: 本文聚焦于2011至2019年期间四川省各地级市的相关数据，旨在探究数字普惠金融如何影响经济的高质量增长。为了全面评估经济高质量发展的水平，采用了熵权法，这是一种客观赋权的多指标综合评价方法，用以构建四川省各地级市的经济高质量发展指标体系。进一步地，通过构建并运用多元回归模型，本文对数字普惠金融与经济高质量发展之间的内在联系进行了实证分析。研究结果揭示了数字普惠金融在四川省不同地区促进经济高质量发展的积极作用。本研究通过机制分析发现数字普惠金融的覆盖广度是提升地区经济高质量发展水平的核心驱动因素，而其使用深度和数字化程度对于促进效应的贡献并不显著。为了进一步验证这一发现，本文采用了主成分分析法对经济发展水平进行了重新构建，并将其作为新的因变量纳入回归模型中。本文不仅为理解数字普惠金融在地方经济发展中的作用提供了新的视角，也为政策制定者提供了关于如何更有效地利用数字普惠金融以推动经济高质量发展的宝贵信息。

Abstract: This paper focuses on the relevant data of prefecture-level cities in Sichuan Province during the period from 2011 to 2019, aiming to explore how digital inclusive finance affects the high-quality growth of the economy. In order to comprehensively assess the level of high-quality economic development, this paper adopts the entropy weight method, which is an objectively empowered multi-indicator comprehensive evaluation method, to construct the index system of high-quality economic development for each prefecture-level city in Sichuan Province. Further, by constructing and applying a multiple regression model, this paper empirically analyzes the intrinsic connection between digital inclusive finance and high-quality economic development. The findings reveal the positive role of digital inclusive finance in promoting high-quality economic development in different regions of Sichuan Province. Through mechanism analysis, this study finds that the breadth of coverage of digital inclusive finance is the core driver of enhancing the level of high-quality development of regional economies, while the depth of its use and the degree of digitization does not contribute significantly to the promotion effect. To further validate this finding, we used principal component analysis to reconstruct the level of economic development and included it as a new dependent variable in the regression model. Encouragingly, the results of the empirical analysis maintain robustness. In addition, the results of the heterogeneity analysis indicate that digital inclusive finance has a more significant role in promoting high-quality economic development in cities with more developed economies. In light of these findings, Sichuan Province should pay special attention to the popularization and enhancement of financial services in backward areas in the future promotion and development of digital inclusive finance. Strengthening the inclusive features of digital finance can not only effectively promote the high-quality development of the local economy but also facilitate the realization of the goal of common prosperity, thus achieving social equity and harmony in economic development. This paper not only provides new perspectives for understanding the role of digital financial inclusion in local economic development, but also provides policymakers with valuable information on how to more effectively utilize digital financial inclusion to promote high-quality economic development.
