Abstract: Based on the perspective of resource mismatch, this paper discusses the effect and mechanism of land transfer scale on the high-quality development of the region, in order to provide reference for the high-quality development of China's region. The results show that the scale of land transfer and the high-quality development of the region show an inverted "U"-type relationship, in the process of land transfer scale expansion, the two-handed land supply strategy of local government low-cost transfer of industrial land and high-priced land transfer business has caused land price distortion, which further aggravates the inhibition effect of land transfer scale on the high-quality development of the region. And through the upgrading of regional industrial structure and regional innovation level, the high-quality development of the region is affected by the influence of land transfer scale on the development of high-quality in the region. At the same time, it has triggered a distortion in the structure of public expenditure.
