Studying construction land expansion (CLE) characteristics and driving factors in resource-based cities (RBCs) is important to promote efficient land use and maintain ecological equilibrium in RBCs. This study explores the CLE and its driving factors in RBCs. The results indicated that (1) the CLE in RBCs became increasingly obvious, and the number of cities with expansion areas exceeding 20 km increased from 29 to 86. In RBCs in different regions, CLE in eastern, central, and western regions was obvious, while CLE in the northeast region decelerated. The order of CLE degree at different stages of RBCs was mature, growing, regenerative, and declining. (2) Single factors such as gross domestic product, fixed-asset investment, and secondary industry added value, playing a major role. This differs from the dominant role of population and urbanization in existing research. This occurred because population growth is slow, the urbanization rate is low, population contraction prominently occurs, and economic development exhibits notable path dependence in RBCs. (3) Interaction-factor detection demonstrated that the force of two-factor interaction was greater than that of a single factor, and the interactions of total population with fixed-asset investment and economic development level strongly drove CLE in RBCs.
研究资源型城市（RBCs）建设用地扩张（CLE）的特征及其驱动因素，对于促进RBCs 高效用地和维护生态平衡具有重要意义。本研究探讨了 RBCs 中的 CLE 及其驱动因素。结果表明：（1）RBCs 中的 CLE 日益明显，扩张面积超过 20km²的城市数量从 29 个增加到 86 个。在不同地区的 RBCs 中，东部、中部和西部地区的 CLE 明显，而东北地区的 CLE 则减速。RBCs 不同发展阶段的 CLE 程度顺序为成熟、增长、再生和衰退。（2）单一因素，如国内生产总值、固定资产投资和第二产业增加值，发挥了主要作用。这与现有研究中人口和城市化的主导作用不同。这是因为 RBCs 中的人口增长缓慢、城市化率低、人口收缩明显以及经济发展表现出显著的路径依赖。（3）交互因素检测表明，两因素相互作用的力量大于单一因素，总人口与固定资产投资和经济发展水平的相互作用强烈推动了 RBCs 中的 CLE。
