摘　　要：利用生产函数模型,运用2000—2008年武汉城市圈数据,计算农地城市流转对经济增长的贡献率、贡献额及边际产出,综合分析比较时间、空间及配置方式上的配置效率及其差异。研究表明:(1)武汉城市圈经济发展的主要动力来自农地城市流转,城镇用地对经济增长平均贡献率为27.49%;(2)存在时间上配置失衡和效率损失,部分年份农地城市流转过度;(3)城市圈西南部的仙桃、咸宁两市城镇用地对经济贡献率较高,另外7市的贡献率基本呈自西向东、自南向北递增的分布规律;(4)城市圈土地市场配置程度逐年上升,黄石、孝感配置方式效率较高,仙桃、潜江、天门则相对较低。为提高农地城市流转配置效率,促进区域经济协调可持续发展,政府应该:严控农地城市流转量,节约集约利用城镇土地;进行区域间的农地城市流转指标调整,制定财政转移补贴政策;加强土地市场建设及宏观调控。The purpose of study is to calculate the allocation efficiency of rural-urban land conversion in Wuhan metropolitan area in the dimensions of time,space,and allocation patterns and to provide a theoretical basis and decision reference for improving the efficiency of land resource allocation.Based on the comprehensive analysis and comparison of inefficiency in the dimensions of time,space,and allocation patterns,this paper employed panel data which ranged from 2000 to 2008of the cities in Wuhan metropolitan area to calculate the allocation efficiency of rural-urban land conversion with the Cobb-Douglas production function model.The results indicated that rural-urban land conversion played a significant role in economic growth because the contribution rate of urban land to economic growth reached to 27.49%;in dimensions of time,misallocation and efficiency loss existed,and there was excessive rural-urban land conversion in some years;in dimension of space,the two cities（Xiantao and Xianning ocated in the southwest of Wuhan metropolitan area）showed the highest contribution rate of urban land to economic growth,the other 7cities showed a spatial distribution regularity that from west to east and south to north the contribution rate increased gradually;in the dimension of allocation patterns,the degree of market allocation of rural-urban land conversion in Wuhan metropolitan area had been strengthened year by year,and the efficiency of allocation patterns was higher in Huangshi and Xiaogan while it was lower in Xiantao,Qianjiang and Tianmen.It is concluded that,in order to improve the allocation efficiency of rural-urban land conversion and promote the coordinative and sustain-able development of regional economy,government can do as follows ：in temporal dimension,to control over the amount of land conversed from rural to urban strictly,to use the increased construction land intensively,and to vitalize the stock construction land;in spatial dimension,to adjust rural-urban land conversion indicators between diffe
