Based on the panel data of 41 prefecture-level resource-based cities in the Yellow River Basin from 2000 to 2019 and the relationship between urbanization and industrial collaborative agglomeration on land use efficiency, this paper uses spatial autocorrelation analysis and spatial Durbin model to analyze the spatial spillover effect of urbanization and industrial collaborative agglomeration on land use efficiency. The threshold regression model is used to discuss the threshold characteristics of industrial collaborative agglomeration in resource-based cities, and the crowding effect matrix table is innovatively constructed. The results show that the land use efficiency among resource-based cities in the Yellow River Basin is geographically correlated with the same high agglomeration or the same low agglomeration in space, and the spatial spillover inhibitory effect of urbanization accounts for 70% of the total inhibitory effect, showing an inhibitory effect. The spatial spillover growth effect of industrial collaborative agglomeration accounts for 70% of the total growth effect, and the spatial spillover inhibitory effect accounts for 20% of the total inhibitory effect, which shows the role of rapid promotion and gradual inhibition. After 2014, the agglomeration effect of some resource-based cities in the Yellow River Basin has accelerated to the threshold, among which Luoyang, Shizuishan, Shuozhou, Wuhai and Jinchang perform well and have the best agglomeration. Baotou and Ordos form a collaborative relationship between cities. The industrial agglomeration of most resource-based cities is still insufficient or crowded, and the future development should combine the characteristics of the city itself to play a synergistic role between adjacent cities.

针对黄河流域沿岸资源型城市城镇化和产业协同集聚对土地利用效率的影响, 基于2000—2019年黄河流域41个地区级资源型城市的面板数据, 采用空间自相关分析方法和空间杜宾模型, 解析城镇化和产业协同集聚对土地利用效率影响的空间溢出效应, 基于门槛回归模型, 讨论资源型城市产业协同集聚的门槛特征, 并构建拥挤效应矩阵表, 得到如下结果。1) 黄河流域资源型城市之间的土地利用效率在空间上呈现以同高集聚或同低集聚为主的地理相关分布格局, 且城镇化的空间溢出抑制效应占总抑制效应的70%, 表现出抑制作用; 产业协同集聚的空间溢出增长效应占总增长效应的70%, 空间溢出抑制效应占总抑制效应的20%, 表现出快速促进和逐渐抑制的作用。2) 2014年后, 部分黄河流域资源型城市的集聚效应向门槛聚集的程度加快, 其中洛阳、石嘴山、朔州、乌海和金昌表现优秀, 集聚效应最佳; 包头和鄂尔多斯形成城市间协同关系。3) 资源型城市产业集聚总体上表现出集聚不足或拥挤的特征, 未来发展中应结合城市自身的特点, 发挥相邻城市间的协同带动作用。
