东北师范大学冯章献团队的最新研究以中国东北城市收缩的案例为研究对象，探讨了“城市收缩是如何影响土地利用效率”的这一问题。2024年1月23日出版的《中国地理科学》杂志发表了这项成果。

研究人员利用Super-SBM-Undirable模型和结构方程模型(SEM)，计算了中国东北地区城市收缩的土地利用效率（LUE），并模拟了城市收缩影响土地利用效率的城市收缩过程。为了量化城市收缩对城市效率利用的影响过程，本研究以经济、公共服务和创新，这三个中介变量为潜在变量，应用SEM进行研究。

研究表明，城市收缩通过直接和间接影响土地利用效率。在直接路径上，城市收缩使得LUE被改善。在间接路径上，经济和创新将传递城市收缩对LUE的负面影响，而公共服务将扭转这一局面。结果强调，本研究的一个重要贡献是量化了影响LUE的城市收缩路径，从而拓展了对城市收缩效应的认识，为收缩城市的可持续发展奠定了基础。

据研究人员介绍，城市收缩效应逐渐成为一个新的话题。从理论上讲，城市收缩可能通过不同的城市子系统对土地利用效率产生巨大影响，但目前对这些途径的研究有限。

Abstract: The effect of urban shrinkage has gradually become a new topic. Theoretically, urban shrinkage may exert great influence on land use efficiency (LUE) through various urban subsystems, but there is currently limited research examining these pathways. Using the Super-SBM-Undesirable model and the Structural Equation Model (SEM), this study calculates the LUE of shrinking cities in Northeast China and simulates the process of urban shrinkage affecting LUE. To quantify the process of urban shrinkage affecting LUE, three mediation variables, namely the economy, public services, and innovation, are used as latent variables to apply SEM. The results show that urban shrinkage will affect LUE through a direct path and indirect paths. In the direct path, urban shrinkage leads to an improvement in LUE. In the indirect paths, the economy and innovation will transmit the negative effect of urban shrinkage on LUE, while public services will reverse this effect. An important contribution of this study is that it quantifies the paths of urban shrinkage affecting LUE, thereby expanding the understanding of urban shrinkage effect and laying a foundation for the sustainable development of shrinking cities.
