近年来青海省经济及城镇化建设得到了快速发展,但区域差异明显、城乡收入差距问题长期存在,如何做好城乡统筹发展工作值得研究。本文以海东市为例,运用格兰杰因果关系检验的方法定量研究城镇化建设与缩小城乡收入差距的关系,检验表明城镇化与城乡收入差距之间存在因果关系,青海省东部城镇化建设的发展策略,将有利于缩小城乡居民的收入差距。 In recent years, Qinghai Province has achieved rapid economic and urbanization. However, with obvious regional differences and long-standing income gap between urban and rural areas, it is worth studying how to make a balanced development of urban and rural areas. Taking Haidong City as an example, this paper uses Granger causality test to quantitatively study the relationship between urbanization and narrowing the income gap between urban and rural areas. The test shows that there is a causal relationship between urbanization and urban-rural income gap, and urbanization in the eastern part of Qinghai Province Development strategy will help narrow the income gap between urban and rural residents.
