基于城镇化和产业结构的城乡收入差距分析

An Analysis of the Urban-Rural Income Gap based on the Urbanization and Industrial Structure

随着国民经济的增长,中国的城镇化水平不断提高,产业结构也日趋合理化,但城乡收入差距却呈现出缩小-扩大-缩小的趋势。本文分析了城镇化水平和产业结构调整的协同性,并运用中国1978年至2014年的数据构建向量自回归模型,利用结构扭曲系数分析城镇化和产业结构双因素作用对中国城乡收入差距的影响,发现第一产业结构扭曲系数与城乡收入差距呈U型,第三产业结构扭曲系数与城乡收入差距呈倒U型,城镇化与产业结构与城乡收入差距呈现∽型。

With economic growth, China＇s urbanization level enhances unceasingly, and the industrial structure is more reasonable, but urban-rural income gap shows narrowing-expanding-narrowing trend. This paper analyzes the synergistic effect between the urbanization level and the industrial structure adjustment, builds the vector autoregressive model by use of the 1978-2014 data, and analyzes the impact of urbanization and industrial structure on the urban-rural income gap using the structure distortion coefficient. The results show that distortion coefficient of the first industrial structure shows U-shaped with the urban-rural income gap, distortion coefficient of third industry structure shows inverted U- shaped with the urban-rural income gap, and the urbanization and industrial structure presents -shaped with the ur- ban-rural income gap.
