摘　　要：首先根据C-D生产函数理论推导定量评价建设用地的集约系数与粗放系数模型逻辑关系的合理性,然后采用势分析方法确定河南省及其各市劳动和资金产出的弹性系数,最后计算其建设用地的集约系数与粗放系数,并根据建设用地利用集约系数和粗放系数这2个重要参数确定其建设用地利用发展模式。This paper deduced the rationality of logical relation for the evaluation model based on C-D product function to quantitatively evaluate intensive and extensive degree of land-use, then defined the elasticity coefficient of labor and capital of Henan province and its cities with the method of potential analysis, finally calculated the intensive coefficient and extensive coefficient of the construction land-use and evaluated their development models of the construction land-use based on these two important parameters.
