数字金融对新质生产力的影响特征研究
The Impact Characteristics of Digital Finance on New Quality Productivity
摘要
Abstract
Developing new quality productivity is an inherent requirement and an important focus for promoting high-quality development.Characterized by technological intensity,the development of new quality productivity requires adequate financial sup-port.Based on panel data from 30 provincial-level administrative regions in China from 2012 to 2023,this paper employs a range of econometric methods,including ordinary least squares(OLS)regression,instrumental variable-two-stage least squares(IV-2SLS),and lagged regression,to validate the impact of digital finance on new quality productivity.Building upon these results,threshold effect models and spatial Durbin models are applied to systematically explore the non-linear and spatial effects of digital fi-nance.The findings reveal that:(1)digital finance significantly promotes the enhancement of new quality productivity;(2)the impact of digital finance exhibits a significant threshold effect related to the scale of social financing,with its promoting effect further strengthening as the scale expands,showing a nonlinear pattern;(3)the development of new quality productivity across provinces exhibits a certain degree of spatial interdependence,whereby improvements in local new quality productivity generate positive spillo-ver effects on neighboring regions;(4)the improvement of digital finance levels in adjacent regions can indirectly inhibit the deve-lopment of local new quality productivity through a"siphon effect".This paper innovatively reveals the threshold and spatial effects of digital finance on new quality productivity,providing a novel perspective for understanding inter-provincial economic integration.Furthermore,it offers theoretical and practical insights for advancing the construction of a"strong financial nation"and fostering new quality productivity.关键词
