作为存量时代优化资源配置的重要手段，城市更新在培育与发展新质生产力方面发挥着关键支撑作用。基于2015—2024年中国沪深A股上市公司数据，立足资源重置效应视角，运用双重差分模型实证检验城市更新政策对企业新质生产力的影响及其作用机制。研究发现，城市更新能够显著提升企业新质生产力水平，且技术创新、数字化水平提升与劳动生产率跃升是城市更新通过资源重置驱动企业新质生产力形成的重要路径。城市更新的赋能作用具有明显的资源禀赋依赖特征，在政府财政实力较强地区、东部地区以及国有企业和大型企业中，城市更新对企业新质生产力的促进效应更为凸显。基于研究结论提出政策建议，以期为推动城市更新治理转型、实现要素均衡配置及促进新质生产力高质量发展提供经验证据和决策参考。

As a pivotal instrument for optimizing resource allocation in the post-incremental era， urban renewal plays a cornerstone role in fostering and advancing new quality productive forces. Utilizing panel data from China's Shanghai and Shenzhen A-share listed companies spanning 2015 to 2024， this study empirically examines the impact of urban renewal policies on corporate new quality productive forces and its underlying mechanisms from the perspective of resource reallocation effects， employing a Difference-in-Differences model. The findings reveal that urban renewal significantly enhances the level of corporate new quality productive forces. Specifically， technological innovation， digitalization enhancement， and labor productivity surges emerge as vital pathways through which urban renewal drives the formation of new quality productive forces via resource reallocation. Moreover， the empowering role of urban renewal demonstrates significant resource endowment dependence： the promotional effect is more pronounced in regions with robust fiscal capacity， the eastern region， as well as among state-owned enterprises and large-scale firms. Based on these conclusions， policy recommendations are formulated to provide empirical evidence and strategic insights for transforming urban renewal governance， achieving balanced factor allocation， and facilitating the high-quality development of new quality productive forces.
