科技金融与新质生产力:时空演化特征及动态互动效应OA

New quality productivity is mainly driven by technological innovation,and technology finance provides critical support for scientific and technological innovation activities by establishing a diversified capital supply system.The two have formed a certain dynamic interactive relationship.Based on the panel data of 30 provinces and 279 cities at prefecture level and above in China,this paper systematically analyzes the spatiotemporal evolution characteristics and dynamic interaction effects of technology finance and new quality productivity by using the entropy weight-TOPSIS method,kernel density estimation,Jenks natural breaks classification method and PVAR model.The results go as below:The development levels of both show an overall upward trend,but there are significant regional differences.In terms of dynamic relationships,a unidirectional Granger causality exists,where new quality productivity significantly drives technology finance,while the boosting effect of technology finance on new quality productivity exhibits heterogeneity,primarily concentrated in the dimensions of labor structure,labor productivity,in-dustrial modernization,pollution reduction and digital infrastructure.
