基于2003至2022年中国31个省份数据构建城乡融合评价指标体系，涵盖经济、社会、空间、生态及人口五个维度。通过运用熵权TOPSIS、核密度估计、Dagum基尼系数分解及Markov链等方法，系统定量分析了中国城乡融合发展的动态演变与区域差异。研究表明，全国城乡融合水平虽呈逐步上升趋势，但整体水平仍偏低，且各区域及区域内部不均衡现象明显：东部地区总体较高但内部梯度显著，中部在追赶东部方面有所成效，而西部与东北则因结构性制约面临发展缓慢与路径依赖问题。基于以上分析结果，提出了优化城乡资源配置、加快制度创新和强化区域协调的政策建议。

Based on data from 31 provinces in China from 2003 to 2022, this study constructs an evaluation index system for urban-rural integration, encompassing five dimensions: economy, society, space, ecology,and population. Employing methods such as entropy-weighted TOPSIS, kernel density estimation, Dagum Gini coefficient decomposition, and Markov chain analysis, the study systematically and quantitatively examines the dynamic evolution and regional disparities of urban-rural integration in China. The results indicate that, although the overall level of integration has shown a gradual upward trend nationwide, it remains relatively low, with significant imbalances both between and within regions. The eastern region demonstrates a relatively high level of integration but exhibits pronounced internal gradients; the central region has made progress in catching up with the east; while the western and northeastern regions face slow development and path dependence due to structural constraints. Based on these findings, the paper proposes policy recommendations aimed at optimizing urban-rural resource allocation, accelerating institutional innovation, and strengthening regional coordination to promote high-quality and sustainable urban-rural development in China.
