Abstract: Abstract: In recent years, it is great practical and academic value to carry out research on the comprehensive effect of housing prices and talent aggregation among many " Talent Snatch War " cities. This paper uses dynamic panel threshold model to evaluate the impact and mechanism of housing prices on the R&D talent aggregation. Firstly, it found that housing price in the low threshold region has a significant role in promoting the R&D talent aggregation, while the high threshold housing price has a inhibiting effect on the R&D talent aggregation throughout the country. Secondly, the influence direction of housing price on the R&D talent aggregation in eastern China is the same as that in the whole country. The housing price in the middle and western regions is located in the low threshold region, which can inhibit the the R&D talent aggregation, while in the high threshold region, it can significantly promote the the R&D talent aggregation. In addition, there is no significant "herding behavior" effect between the whole country and the eastern region, and there is a "crowding effect" in the eastern region, but the "herding behavior" effect in the central and western regions is significant and positive externality. The conclusion is that in the short run, the cities in the Eastern Region should increase the subsidy of purchasing houses for the R&D talent aggregation, and in the long run, they should take an active part in the "industry-grabbing war" to enhance the agglomeration of high-tech industries. Cities in the central and western regions should seize the strategic opportunity to participate in the " Talent Snatch War ", Making full use of the "herd behavior" effect of talent gathering.
