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（NTU）与乡村振兴（RR）的协同发展是中国提出的构建新型城乡关系范式的关键命题。首先，本研究采用熵值法对新型城镇化和乡村振兴进行量化。随后，运用相对发展度模型（RDDM）、耦合协调度模型（CCDM）、达古姆基尼系数、核密度估计和Tobit模型对二者的耦合关系进行全面分析。研究结果表明，2011—2022年长江经济带新型城镇化与乡村振兴呈持续上升态势，但新型城镇化滞后失调分布广、数量多。新型城镇化与乡村振兴的耦合协调度不断提升，由中度失调向初级协调转变，呈现“东高西低”的空间分布。新型城镇化与乡村振兴耦合发展的相对差距呈缓慢缩小趋势，绝对差距呈扩大趋势。在影响因素中，农业产业发展对耦合发展的正向影响最大，而农业财政支持水平起抑制作用，且具有异质性。
