| 中文摘要 |
| 为响应国家“培育新质生产力”与“长江经济带绿色发展”战略，基于“劳动者-劳动对象-劳动资料”三维度与“压力-状态-响应”模型，分别构建新质生产力与生态环境评价指标体系，运用熵权法、耦合协调模型、核密度估计、标准差椭圆和地理探测器等方法，分析2009~2022年长江经济带108个地级市两系统耦合协调的时空演变与驱动机制. 结果表明：耦合协调度整体提升，呈现“下游>中游>上游”的梯度格局；经济发展是核心驱动力，且与环保投入的交互作用最强；区域异质性显著，上游受工业与环境交互影响，中游依赖教育与科技协同，下游面临经济发展与环境污染矛盾. 研究为长江经济带差异化推进新质生产力与生态环境协同发展提供科学依据. |
| 英文摘要 |
| In order to respond to the national strategies of “cultivating new-quality productivity” and “promoting the green development of the Yangtze River Economic Belt，” this study， grounded in the three-dimensional framework of “laborers-labor objects-labor materials” and the “Pressure-State-Response （PSR）” model， constructs evaluation index systems for new-quality productivity and the ecological environment， respectively. Employing a series of methods including the entropy-weight method， coupling-coordination model， kernel density estimation， standard-deviation ellipse， and geographical detector， this study analyzes the spatio-temporal evolution and driving mechanisms of the coupling and coordination between the two systems in 108 prefecture-level cities within the Yangtze River Economic Belt during the period from 2009 to 2022. The findings indicated that the overall coupling-coordination degree has increased， presenting a gradient pattern of “downstream region > middle-reaches region > upstream region.” Economic development served as the core driving force， and its interaction with environmental protection investment was the most prominent. There were significant regional heterogeneities. In the upstream region， the interaction between industry and the environment played a crucial role； the middle-reaches region relied on the synergy between education and technology； while the downstream region faced the conflict between economic development and environmental pollution. This research offers a scientific foundation for the Yangtze River Economic Belt to promote the coordinated development of new-quality productivity and the ecological environment in a differentiated manner. |
