中文摘要：

评价区域土地经济密度并研究其内在影响机理对指导区域城市健康可持续发展具有重要指导意义。文章以中原经济区为研究对象,分析30个城市2002-2012年间的土地经济密度,并采用空间分析法和面板数据模型对土地经济密度的区域差异和影响机理进行探讨。结果表明：（1）中原经济区土地经济密度总体呈不断上升趋势,但个别城市近年来有所下降;（2）土地经济密度总体差异上下波动有缩小趋势,其中核心区区内差异是总体差异主要来源;（3）土地经济密度在整体上没有显著空间集聚,各城市土地经济密度呈现随机分布状态;（4）人口规模、经济水平、城市化水平和产业结构对土地经济密度具有显著影响,且呈正相关态势。

英文摘要：

It is of great significance to evaluate regional land economical density and explore the inner influence mechanism for guiding sustainable urban development. This paper analyses the land economic density from 2002 to 2012 in 30 cities of Central Plains Economic Zone. By using the method of spatial analysis and panel data model, it also discusses the regional differences and the effect mechanism pertaining to land economic density. The results shows that the land economical density in Central Plains Economic Zone is growing comprehensively, while in some cities it＇s declining recently; the difference of land economical density in different cities is narrowing and the difference from core city areas contributes the most part of it; there＇s no signifi cant spatial agglomeration of land economical density as a whole, the density in different cities displays in a random way; the population, economical level, urbanization level and industrial structure are the main constituents that have a signifi cant impact on land economical density and show the positive correlation.
