Abstract Based on the theory of competitive advantage, this article analyzes the driving mechanism of regional integration on the competitiveness of scientific and technological talents. On this basis, using kernel density estimation and non-dynamic panel threshold regression model, empirical analysis of the influence of the integration of the Yangtze River Delta on the competitiveness of scientific and technological talents and the economic and income threshold effects. The study found that: ①the level of regional integration in the Yangtze River Delta has increased significantly, the differences in the level of integration between cities have expanded, and the spatial agglomeration effect is significant, forming a high-level integrated agglomeration zone of "the area south of the Yangtze River" and "the area around Taihu Lake";②The competitiveness of scientific and technological talents has been increasing year by year, the gap in the level of competitiveness of scientific and technological talents between cities has gradually narrowed, and the multi-center situation has gradually emerged, but the "Matthew effect" is still significant;③The influence of the integration of the Yangtze River Delta on the competitiveness of scientific and technological talents has significant economic development and income level thresholds, and the influence coefficients respectively show a "U"-shaped and inverted "U"-shaped change trend.
