ABSTRACT: Based on the data of 30 provinces in 2010, 2013, 2016, 2019, and 2022, this paper constructed a comprehensive evaluation system of high quality economic productivity, the dynamic model, Dagum gini coefficient, Moran index, Kernel density estimation, and studied the coupling coordination characteristics, regional differences and dynamic evolution rules. The research shows that the coupling and coordination degree of new quality productivity and high-quality economic development in China shows significant regional differences in space, the overall level remains relatively low, it presents the gradient distribution pattern of east & gt; central & gt; west. Although the overall difference has narrowed, the coupling coordination degree still shows distinct differentiation characteristics in space, the dynamics between and within regions remain significant, in particular, the internal differences in the central region are further intensified. Coupled coordination degree has a significant agglomeration effect in space, the eastern region mainly presents a & quot; high-high & quot; agglomeration, While the central and western regions are mainly & quot; low-low & quot; agglomeration, the imbalance of regional development is particularly prominent.
