中国城市土地利用效率测度

Measurement on China’s urban land use efficiency

城市土地利用效率是土地资源优化配置的重要评价标准。基于30个省市自治区的面板数据,运用修正的Hybird-Meta-Frontier窗口模型,测算了中国各区域的城市土地利用效率。结果显示:在共同前沿下,全国城市土地利用效率平均水平较低,呈现出东部—中部—西部—东北地区递减的趋势;随时间推移,东部、中部、西部地区的城市土地利用效率曲折上升,东北地区的城市土地利用效率波动较大;在群组前沿下,四大区域的城市土地利用效率随时间变化表现各异,东部、中部、西部地区的城市土地利用效率的层级差异缩小,东北地区的城市土地利用效率依然波动较大。据此认为,在城市化建设中,应加强对城市存量建设用地的挖潜力度,转变"土地财政"的发展方式,加快推进新型城镇化建设。

Urban land use efficiency is an important criterion for the optimal allocation of regional land resource.In this esasy,the application of modified Hybrid-Meta-Frontier window model,which uses the yearbook database from 2003 to 2016 in 30 provinces across the country,measures the urban land use efficiency.The research results show:On the average,china's urban land use efficiency,under the common frontier,is rather low,being a declining trend in the east,central,west,and the northeast regions;As time passes by,the efficiency in the east,central,and west regions climbs up circuitously,while intense fluctuation can be seen in northeast region;Under the group frontier,the efficiency in those four regions witnesses a time-varied performance:the difference in regional level in the east,central and west regions has narrowed,but strong fluctuation can still be detected in the northeast region.In the end,it proposes enhancing the potential of tapping the land reserve construction in urban areas,transforming the development pattern that local governments rely on the land revenue,and accelerating the construction of new urbanization.
