Abstract: Based on the four dimensions of innovation funding, innovation manpower, innovation institutions and innovation achievements, the entropy method was used to measure the level of China's innovation factor agglomeration from 2009 to 2019, and the Dagum Gini coefficient decomposition and variance decomposition were used to analyze the spatial and structural aspects. From the perspective of revealing the differences and sources of the agglomeration level of innovation elements in China, and using the QAP method to study the formation mechanism of the differences in the agglomeration of innovation elements. The research finds that the level of innovation factor agglomeration is low but shows a slow upward trend, among which innovation manpower agglomeration, innovation institution agglomeration and innovation achievement agglomeration continue to improve, while innovation funding agglomeration shows a downward trend; regional differences are the main source of differences in innovation factor agglomeration. , the internal differences in the eastern region are significantly higher than those in the central and western regions, and the internal differences in the Yangtze River Basin are larger than those in the Yellow River Basin; the difference in the agglomeration of innovation achievements is the main structural source of the difference in the agglomeration of innovation elements; the intensity of the effect of the difference in the agglomeration of innovation funds on the difference in the agglomeration of innovation elements varies from east to west The intensity of the effect of the agglomeration difference of innovation achievements is gradually weakened. The difference in the agglomeration of innovation manpower and the agglomeration of innovation institutions has the greatest effect in the central region.
