| 中文摘要 |
| 新质生产力作为驱动经济高质量发展的核心动能，其与土地利用效率的协同关系是区域可持续发展的重要议题. 基于2010~2023年中原城市群29个地级市面板数据，综合运用熵权-TOPSIS法、超效率SBM模型、Malmquist指数与固定效应模型，系统解析新质生产力时空演变规律及其对土地利用效率的影响机制. 结果表明：①中原城市群新质生产力综合指数从0.280增长至0.828，呈现“阶梯式上升”态势；空间格局上形成“核心-次级-外围”三级梯度分布特征. 其中，郑州作为核心增长极发挥创新引领作用，邯郸、鹤壁等外围城市因资源型经济结构制约，新质生产力指数普遍低于0.2. ②研究区土地利用效率均值从0.917提升至1.031，河南省内城市整体表现优于河北、山西和安徽这三省，全要素生产率年均增长16.4%，技术进步为主要驱动因素. ③新质生产力对土地利用效率具有显著正向影响，但存在明显异质性：经济规模较大的城市通过技术集聚与产业升级能够显著提升土地集约利用水平；耕地资源较少及经济发展水平较高的城市能够有效发挥新质生产力对土地利用效率的促进作用；而规模较小、耕地资源丰富及经济发展水平较低的城市受技术吸纳能力、路径依赖及要素瓶颈制约，尚未建立有效的协同机制. |

| As a core driver of high-quality economic development， the synergistic relationship between new quality productive forces（NQPF）and land use efficiency（LUE）constitutes a critical issue in regional sustainable development. Utilizing panel data from 29 prefecture-level cities in the Central Plains Urban Agglomeration （2010-2023）， this study integrates the entropy weight TOPSIS method， super-efficiency SBM model， Malmquist index， and fixed-effects model to systematically analyze the spatiotemporal evolution of NQPF and their impact mechanisms on LUE. The results show that： ① The composite index of NQPF in the Central Plains Urban Agglomeration increased from 0.280 to 0.828， exhibiting a “stepwise growth” pattern， with a spatial structure characterized by a “core-secondary-periphery” gradient. Zhengzhou emerged as the core growth pole driving innovation， while peripheral cities such as Handan and Hebi， constrained by resource-dependent economic structures， exhibited NQPF indices below 0.2. ② The mean LUE in the study area improved from 0.917 to 1.031， with cities in Henan Province outperforming those in Hebei， Shanxi， and Anhui provinces. Total factor productivity （TFP） grew at an annual rate of 16.4%， primarily driven by technological progress. ③ NQPF exerted a significantly positive effect on LUE， albeit with notable heterogeneity： Large-scale cities enhanced land-intensive utilization through technological agglomeration and industrial upgrading； cities with limited arable land resources and higher economic development levels effectively leveraged NQPF to improve LUE. In contrast， small-scale cities， arable-rich regions， and economically underdeveloped areas， hindered by technological absorption capacity， path dependence， and resource bottlenecks， failed to establish effective synergistic mechanisms. |
