The emergence of scientific and technological innovation,the penetration and integration of factors,the expansion,extension and strengthen of the industrial chain,and the reconstruction of new production relations are the four links of the devel-opment of new quality productivity.This paper is based on the four links of new quality productivity development to construct the evaluation index system of new quality productivity development level,then uses the entropy weight-TOPSIS method and the cou-pling coordination degree model to measure the level of new quality productivity in 30 provinces of China from 2012 to 2022,and finally,uses the Dagum Gini coefficient method,the global Moran's index and the Kernel density estimation to investigate the re-gional differences of new quality productivity development level.The results go as the following:(1)The development level of Chi-na's new quality productivity is increasing year by year,and the new quality productivity development level in the four regions presents a development pattern of easterncentralnortheastwest.Among the four links,the degree of fit between the emer-gence of scientific and technological innovation and the penetration and integration of elements is high,but it is still the"short board"of most provinces.(2)There are obvious spatial differences in the development level of new quality productivity,but the overall development trend is gradually decreasing,and inter-regional differences are the main source of regional differences.(3)The emergence of scientific and technological innovation and the penetration and integration of factors are the hard conditions for the development of new quality productivity,while the expansion,extension and strengthening of industrial chain and new produc-tion relationship reconstruction are the soft conditions,which form the hard power and soft power,respectively.The improvement of hard power depends on its own resource endowment,and the improvement of soft power can be achieved through inter-provin-cial cooperation.(4)The spatial extensibility of the development level of new quality productivity is increasing year by year;the absolute difference is expanding,and the polarization characteristics are gradually weakening.
