The coupled development of new-type urbanization (NTU) and rural revitalization (RR) represents a critical proposition put forth by China for forging a novel paradigm of urban-rural relationship. Initially, this study employs the entropy method to quantify NTU and RR. Subsequently, it carries out a comprehensive analysis concerning their coupled relationship with the relative development degree model (RDDM), coupled coordination degree model (CCDM), Dagum Gini coefficient, kernel density estimation, and Tobit model. The findings drawn from the study indicate from 2011 to 2022, NTU and RR in the Yangtze River Economic Belt (YREB) have exhibited a consistent upward trajectory, but lagging NTU disorders are widely distributed and numerous. The coupled coordination degree (CCD) of NTU and RR constantly improves, transitioning from moderate imbalance to primary coordination, exhibiting a spatial distribution of a "high in the east and low in the west". The relative disparity between the coupled development of NTU and RR demonstrates a slowly narrowing trend, whereas the absolute disparity indicates an expanding trend. Among the influencing factors, the development of the agricultural industry exerts the most significant positive impact on the coupled development, whereas the level of financial support for agriculture exerts a dampening effect, which is heterogeneous in nature.

新型城镇化（New-type Urbanization, NTU）与乡村振兴（Rural Revitalization, RR）的耦合发展，是中国提出的构建新型城乡关系范式的重大战略命题。本研究首先采用熵值法对NTU与RR进行量化测度；随后运用相对发展度模型（Relative Development Degree Model, RDDM）、耦合协调度模型（Coupled Coordination Degree Model, CCDM）、达古姆基尼系数（Dagum Gini Coefficient）、核密度估计（Kernel Density Estimation）以及Tobit模型（Tobit Model），对二者的耦合关系展开系统性综合分析。研究结果表明：2011至2022年，长江经济带（Yangtze River Economic Belt, YREB）的NTU与RR均呈现持续上升的发展态势，但城镇化滞后现象分布广泛且较为普遍。二者的耦合协调度（Coupled Coordination Degree, CCD）不断优化升级，从中度失调阶段逐步过渡至初级协调阶段，空间分布呈现“东高西低”的格局。二者耦合发展的相对差距呈缓慢收窄趋势，而绝对差距则呈扩大态势。在影响因素层面，农业产业发展对耦合发展的正向驱动作用最为显著，而农业财政支持水平则产生抑制效应，且该效应存在显著异质性。
