新质生产力对中国经济增长的影响OA北大核心

This paper constructs the evaluation index system of new quality productivity from the three elements of substance and the two characteristics of permeability,and scientifically measures its development level.This paper selects the inter-provincial panel data from 2011 to 2022,and uses dual-fixed model,mediating model,regulating model and spatial lag model to examine the direct mechanism,mediating mechanism,regulating mechanism and spatial spillover effect of new quality productivity on economic growth.The results show that:(1)the new quality productivity has a significant effect on promoting regional economic growth,and the central region is the most significant,followed by the eastern region;(2)the new quality productivity can play a mediating effect through the action path of factor agglomeration and promote the improvement of economic development level;(3)industrial structure upgrading can positively adjust the effect of new quality productivity on economic growth;(4)the development of new quality productivity has a significant spatial spillover effect on economic growth,which has a negative inhibition effect in the short term,but a positive promotion effect in the long term.Based on this,we put forward policy suggestions on implementing the innovation-driven strategy,promoting the integrated development of innovation chain and industrial chain,giving full play to the effect of digital empowerment,deepening the integration of digital technology and the real economy,developing new quality productivity according to local conditions,and alleviating regional development imbalances.
