竞争激励下城市供地策略互动与压力响应

Interaction and Pressure Response of Land Supply Strategies under Competitive Incentives

从地方政府间竞争激励视角出发,运用空间计量模型剖析了城市策略性供地的空间互动效应及压力响应。研究发现:同省份地级市之间供地策略存在显著的空间互动特征,且省内经济发展水平相近、地理位置邻近的地级市之间空间互动效应更强。分用途来看,相比于高价出让住宅用地获取更高土地溢价的土地财政行为动机,地方政府基于工业用地进行招商引资的行为动机所引发的相互模仿、跟随的空间互动效应更强。进一步讨论表明,地方政府面临的财政压力、增长压力和晋升压力等压力对不同用途供地策略空间互动特征的影响存在显著差异。此外,低经济发展水平城市更倾向于模仿高经济发展水平城市的供地策略,且低经济发展水平城市之间的供地策略空间互动效应明显更强。

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.
