[Objective/Significance] In view of the strategic requirements of intellectual property power and the important position of new material industry in the future development of high-tech industry in China, this paper aims to explore the spatial distribution characteristics and spatial-temporal dynamic evolution trend of high-value patents in China's new material industry, to enrich high-value patent research and offer targeted advice for new material industry development, so as to help China win the initiative in the strategic competition of new material industry in the future. [Method/Process] This paper collects high-value patent data of new materials industry in 30 provinces(autonomous region,municipality) in China from Wisdom Sprout Patent Database from 2011 to 2021, and uses exploratory spatial data analysis, Dagum Gini coefficient, and spatial Markov modeling methods to explore the spatial distribution characteristics and spatial dynamics of the high-value patents of China's new materials industry. [Results/Conclusions] High-value patents in China's new materials industry are characterized by spatial aggregation, and the positive spatial correlation is increasing; the overall spatial gap is narrowing but there is still a large gap, and the gap between various regions is the main reason for the overall gap is too large; in the spatial evolution of the Chinese new materials industry, the development of high-value patents exhibits a phenomenon of "club convergence". Regarding the migration of development levels across regions, the probability of upward transfer is greater than that of downward transfer, indicating an overall trend of stable and positive development.
