Based on the night light data of 730 units at the county level in the Yellow River Basin from 2013 to 2021,the paper explores the spatiotemporal distribution characteristics of economic development in the Yellow River Basin by using the methods of gravity center,standard deviation ellipse and spatial autocorrelation analysis,and analyzes the relevant influencing factors with the multivariable linear regression model. The research finds that: On the whole,the economic development in the Yellow River Basin shows uneven distribution which is higher in the east than the west,and core-periphery pattern. The gravity center of economic development in the Yellow River Basin is generally stable with a small offset,which indicates that there are differences in the economic volume in the area,but the differences are gradually narrowing. At the same time,the standard deviation ellipse presents a relatively stable "northeast-southwest" distribution pattern. From the perspective of spatial correlation,there is an obvious positive correlation in the economic development of the Yellow River Basin. The degree of spatial correlation decreases first and then increases. It has strong spatial heterogeneity and regional aggregation characteristics,and the aggregation trend is caused by high aggregation areas. Among the positive factors,industrial structure is the most important factor affecting the economic development,financial development is the secondary,population size and education level are important,government intervention and terrain conditions are restrictive factors.
