宗地规模、城市类型与土地出让溢价——基于70个大中城市住宅用地出让数据的实证分析

Land Size, City Type and Land Auction Premium: Empirical Analysis of Residential Land Leasing Data from Seventy Big and Medium-sized Cities

研究目的:确定住宅用地出让溢价率水平与宗地规模之间的关系,比较不同规模和区位城市中这一关系的差异。研究方法:理论分析,面板数据分析。研究结果:总体上宗地规模对土地溢价率的影响呈现“倒U”型变化关系,不同规模和区位城市中这一关系有差异。人口介于500万~1 000万之间的特大城市中土地溢价水平受宗地规模的影响较为强烈,东部和中部城市中宗地规模大小对土地溢价水平影响显著,西部城市不显著。研究结论:地方政府在总量既定条件下调整宗地投放规模可在一定程度上调控土地溢价率。

The purposes of this paper are to determine the relationship between the level of residential land leasing premium rate and the land size,and to compare the differences in this relationship between cities of different sizes and locations.The methods used include theoretical analysis and panel data analysis.The results show that the impact of the land size on the land premium rate shows a kind of“inverted U”type.And there is a significant difference in the relationship between cities of different scales and locations.Specifically,the land premium level in the mega-cities with a population between 5 million and 10 million is influenced by the land size strongly.In the eastern and central cities,the land size has a significant impact on the land premium level,but Its impact on the western cities is insignificant.In conclusion,the local government can adjust the land supply size in order to pre-adjust the land premiums to a suitable level.
