Abstract: In this article, the spatial interaction effects and pressure responses of strategic land supply among cities were analyzed from the perspective of competitive incentives among local governments using a spatial econometric model. The results show that there is a significant spatial interaction between land supply strategies of prefecture-level cities in the same province, and the spatial interaction effect is stronger among prefecture-level cities with a similar level of economic development and geographical proximity within the province. In terms of use, the spatial interaction effect of imitating and following each other triggered by behavioral motivation of local governments to attract investment based on industrial land is stronger than behavioral motivation of land finance to obtain higher land premiums by offering residential land at high prices. Further discussion shows that pressures faced by local governments, such as fiscal pressure, growth pressure and promotion pressure, have significantly different effects on spatial interaction characteristics of land supply strategies for different uses. In addition, cities with low economic development levels tend to imitate the land supply strategies of cities with high economic development levels, and the spatial interaction effects of land supply strategies among cities with low economic development levels are significantly stronger.
