摘要
土地经济密度作为衡量区域土地利用效率和经济发展的重要指标,对协调经济发展与土地利用之间的关系至关重要。基于济南都市圈7个地市2005—2017年的面板数据,采用空间自相关分析和空间计量模型等方法研究了都市圈土地经济密度的时空演化与影响因素。研究结果表明:(1)济南都市圈土地经济密度整体上呈不断上升趋势,在空间上形成以济南市区、淄博市区为中心的双核高值集聚区,土地经济密度地区差异较为明显;(2)研究区土地经济密度空间集聚性比较稳定,“高-高”集聚类型有淄博市区、章丘区,“无棣-阳信-商河”一线为“低-低”集聚类型,“低-高”集聚类型有济阳县;(3)影响因素的显著性在不同年份存在差异,产业结构、人口密度和城镇化水平是影响济南都市圈土地经济密度的主要因素。
Land economic density,as an significant index to measure the efficiency of regional land use and economic development,is essential to coordinate the relationship between economic development and land-use.Based on the panel data of seven cities in the Ji'nan metropolitan area from 2005 to 2017,the methods of spatial autocorrelation analysis and spatial econometric model were used to study the spatiotempora evolution and impact factor of land economic density in the metropolitan area.The results show that the overall land economic density in Ji'nan metropolitan area is on the rise,forming two major high-level gathering areas in the urban area of Ji'nan and Zibo;and regional disparities are more obvious.The overall differences of land economic density are relatively stable.The space aggregation shows a stable situation.The“H-H”agglomeration types include the urban areas of Zibo and Zhangqiu.The“Wudi-Yangxin-Shanghe”line is a“L-L”agglomeration type,and Jiyang county is“L-H”aggregation type.Industrial structure,density of population and the urbanization level have a positive impact on the land economic density in the Ji'nan metropolitan area.
