摘 要
本研究聚焦于中国城市化进程中城乡收入差距的动态演变特征及其影响因素。基于2000-2020年全国省级面板数据，采用泰尔指数分解法、空间计量模型和门槛回归模型，系统考察了城乡收入差距的时空分异格局、空间溢出效应及非线性演变规律。研究发现：我国城乡收入差距呈现先扩大后缩小的"倒U型"演变趋势，且具有显著的空间集聚特征；经济发展水平、产业结构升级、人力资本积累等因素对缩小城乡收入差距具有积极作用，而财政分权、土地城镇化等变量则表现出抑制作用；进一步研究表明，城乡收入差距存在明显的门槛效应，当城镇化率达到65%时，其对收入差距的收敛作用显著增强。

Abstract
This study focuses on the dynamic evolution characteristics and influencing factors of urban and rural income gap in the process of urbanization in China. Based on the national provincial panel data from 2000 to 2020, the Thier index decomposition method, spatial measurement model and threshold regression model are used to systematically investigate the spatiotemporal differentiation pattern, spatial spillover effect and nonlinear evolution law of urban and rural income gap. The study shows that the urban-rural income gap in China is an "inverted U" that expands first and then shrinks, and has significant characteristics of spatial agglomeration; the factors such as economic development level, industrial structure upgrading and human capital accumulation play a positive role in narrowing the urban-rural income gap, and the variables such as fiscal decentralization and land urbanization show obvious threshold effect. When the urbanization rate reaches 65%, its convergence effect increases significantly.
