摘　　要：新型城镇化进程中政府的财政支出在城乡收入分配和社会公共服务方面发挥了重要作用,是促进城乡融合的重要资金保障。本文基于长三角城市群2014—2020年的有关数据,构建计量经济模型研究新型城镇化和财政支出的规模以及结构对城乡收入差距的影响。通过熵值法测度新型城镇化指标,并将其作为门槛变量进行实证分析。研究发现,长三角地区的新型城镇化水平整体上呈现逐年上升的趋势,但区域内部水平具有非均衡性;新型城镇化、财政支出规模、社会保障支出和科教文卫支出均存在门槛效应,当新型城镇化水平提升到一定的门槛值后,对城乡收入差距的缩小效应增强,财政支出规模和科教文卫支出的作用由扩大差距转向缩小,社会保障支出的作用由不显著影响转向缩小。In the process of new urbanization,government fiscal expenditure has played an important role in urban-rural income distribution and social public services,and is an important financial guarantee for promoting urban-rural integration.Based on the relevant data of the Yangtze River Delta urban agglomeration from 2014 to 2020,this paper constructed an econometric model to study the impact of new urbanization and the scale and structure of fiscal expenditure on the urban-rural income gap.The index of new-type urbanization was measured by the entropy method,and it was used as the threshold variable for empirical analysis.The results showed that the level of new-type urbanization in the Yangtze River Delta was on the rise year by year,but the level within the region was unbalanced.New urbanization,the scale of fiscal expenditure,social security expenditure and expenditure on science,education,culture and health all had threshold effect.When the level of new urbanization was raised to a certain threshold value,the narrowing effect on the income gap between urban and rural areas became stronger,the role of the scale of fiscal expenditure and expenditure on science,education,culture and health turned from widening the gap to narrowing,and the role of social security expenditure turned from insignificant influence to narrowing.
