以柯布一道格拉斯生产函数为基础模型,构建以相邻省份的共同边界线长度和经济发展水平作为空间权重的固定效应空间滞后模型,并利用我国2000—2011年的省级面板数据,实证分析各省份城市土地边际生产率.结果表明：（1）我国二、三产业经济增长存在空间溢出性;（2）在考虑空间溢出性的条件下,城市土地边际生产率包含城市土地直接边际生产率和城市土地间接边际生产率,同时各省份的城市土地间接边际生产率一般低于城市土地直接边际生产率;（3）从城市土地平均边际生产率的大小来看,较高区域依次是福建、上海和河北等地区,较低区域依次是宁夏、新疆和海南等地区.因此,中央政府可依据各省份城市土地平均边际生产率高低差别化配置城市土地,从而提高城市土地总产出,促进经济增长.

Based on the marginal productivity of urban land and panel data of 31 provinces during 2000-2011 inChina,this paper employed Cobb-Douglas production function and established a fixed effects spatial lag modelbased on the spatial weight involving common boundary line length and economic development level of the neigh-boring provinces,and studied the marginal productivity of urban land. The results were that：（1）In the economyof secondary and tertiary industries there exists space overflow;（2）Base on space overflow,the marginal produc-tivity of urban land includes the direct marginal productivity of urban land and the indirect marginal productivityof urban land,and the latter is lower than the former in each province;（3）The highest average marginal produc-tivity of urban land in turn is in Fujian,Shanghai and Hebei,etc;the lowest average marginal productivity of ur-ban land in turn in Ningxia,Xinjiang and Hainan,etc. Therefore,to improve the urban land productivity and pro-mote economic growth,the government can take a differential approach to supplying urban land by taking intoconsideration the average marginal productivity of urban land level in different province.
