徐州市住宅地价空间分异及影响因素

Spatial differentiation and influencing factors of the residential land price in Xuzhou

研究城市住宅地价空间分异及其成因对于城市政府科学制定房地产市场调控政策和促进土地资源优化配置具有重要意义.以徐州市主城区为例,采用克里金法和地理加权回归等方法,对徐州市住宅地价的空间分异及其影响因素进行研究.结果表明:徐州市住宅地价总体呈单中心空间结构和空间向心性;容积率是提升徐州住宅地价的主导因素,医疗资源、公园绿地和教育资源对徐州市住宅地价也有较大的提升作用,且对地价影响具有显著的空间差异性.在主城区范围内,合理布局各影响因素,能够促进土地资源的优化配置和城市土地整体价值的有效发挥,建议适度提高容积率、均衡布局基础设施、科学把握住宅用地供应规模和出让价格.
