深入研究不同类型城市建设用地扩张驱动力,可为差别化调控城市建设用地无序蔓延提供决策支持.基于已有城市职能分类,选择全国1999-2011年137个地级以上城市样本,采用面板数据计量分析法对比分析了4种不同职能城市建设用地扩张特征及其驱动力差异.结果显示：淤区域综合性城市建设用地扩张最快,但其人均城市用地最小,第二产业域城市建设用地年均增长率、城市用地扩张弹性系数及人均用地均为最高,而资源型城市人均用地、城市用地增长率、市均扩张速度及弹性系数均为最低.于城市非农人口、经济增长及人均绿地是影响各类城市建设用地扩张的-般因素,且前者最为重要,后两者的重要性排序在两类第二产业城市相同,而在其他职能城市有差异;特殊因素中,固定资产投资对资源型城市外的其他职能城市均有影响,产业结构调整仅对资源型城市有影响,二者影响力均较小,职工平均工资仅对第二产业域及文化旅游城市有影响,且为文化旅游城市的第二重要性因素.研究表明,不同职能城市建设用地扩张特征各异,且其城市建设用地扩张的驱动力组合及各因素的作用强度存在显著差异,为引导城市建设用地合理扩张,需要针对不同职能城市制定差别化城市建设用地扩张管制政策.

英文摘要：

Understanding the driving forces of urban land expansion in different types of cities is crucial for thedifferential regulation of urban land sprawl. Based on the function classification of Chinese cities,this study se-lected 137 prefecture-level cities from 1999 to 2011. Methods of panel data analysis and comparative analysiswere used to explore the differences of urban land expansion characteristics and driving forces in four differentfunctional cities,i. e. regional comprehensive cities,resources cities,the secondary industrial cities II,and culturaland tourism cities. The results showed that in regional comprehensive cities,the urban land expands fastest,but itsurban land per capita is the smallest. In the secondary industrial cities II,the annual average growth rate,elastic-ity coefficient of urban land expansion,and the urban land per capita are all the highest,while in resources cities,the urban land per capita,the annual average growth rate,the expansion speed per city and elasticity coefficient ofurban land expansion are the lowest. The results also indicated that urban population,economic growth and greenland per capita are common driving factors affecting urban land expansion in various function cities. Among thosecommon factors,urban population is the most important one,and the sort orders of other two factors忆relative im-portance are the same in the two types of the secondary industrial cities,but different in the other two types of cit-ies. The investment in fixed assets,adjustment of industry mix and the workers忆average wage are special factors,of which the investment in fixed assets has effects on various types of cities except resources cities,the factor ofadjustment of industry mix only affects resources cities,and the influence of those two factors are relatively small.The factor of workers＇average wage only has impact on the urban land expansion of cultural and tourism citiesand the secondary industrial cities II,and is the secondary important factor in cultural and tourism cities.
