城乡收入差距的空间演变及其影响因素研究--以甘肃省为例

Spatial Evolution and Influencing Factors of Urban-rural Income Gap-Taking Gansu Province as an Example

以甘肃省为研究对象,分析城乡收入差距的演变趋势,采用空间自相关分析法,对地域空间相关性和集聚性进行分析。再通过建立多元线性回归模型,实证分析城乡收入差距的影响因素。研究结果表明:甘肃省各市州城乡收入比在空间分布上相关性随时间逐渐增强,且呈现出“西低东高”聚集的分布格局。城镇化率、农业机械总动力、农村教育发展水平的提高缩小了甘肃省城乡收入差距,人均GDP、外贸依存度的提高则扩大了城乡收入差距。最后,根据研究结论提出相应政策建议。

Taking Gansu Province as the research object,this paper analyzes the evolution trend of urban-rural income gap,and uses spatial autocorrelation analysis to analyze the regional spatial correlation and agglomeration.Then through the establishment of multiple linear regression model,empirical analysis of urban and rural income gap factors.The results show that the spatial distribution correlation of urban/rural income ratio of cities,states and cities in Gansu Province gradually increases with time,and presents a clustered distribution pattern of"low in the west and high in the east".The improvement of urbanization rate,the total power of agricultural machinery and the development level of rural education narrowed the urban-rural income gap in Gansu Province,while the improvement of per capita GDP and foreign trade dependence widened the urban-rural income gap.Finally,the corresponding policy suggestions are put forward according to the research conclusions.
