山东省金融发展对城乡收入差距作用的实证研究

Empirical Research on Relationship between Financial Development and Urban-rural Income Gap in Shandong Province

通过构建动态面板数据模型对山东省金融发展与城乡收入差距之间的作用关系进行了分析,并采用广义矩法对模型参数进行估计,得到结论:在所有影响因素的联合作用下,山东省金融发展效率起到了扩大城乡收入差距的作用,而金融发展规模对城乡收入差距具有显著抑制作用.其中,金融发展效率的影响强于金融发展规模.另外,产业结构的升级对城乡收入差距具有扩大作用,开放程度的提升对城乡收入差距具有明显的抑制作用,社会保障支出也起到了缩小城乡收入差距的作用.最后,城乡收入差距自身具有显著的滞后效应.

This author analyzes analyzes the relationship between the financial development and the urban-rural income gap of Shandong Province by constructing a dynamic panel data model. The generalized method of moments is used to estimate the parameters of the model. The results show that under the comprehensive effect of all variables,the financial development efficiency of Shandong Province plays a role in expanding the income gap between urban and rural areas,while the scale of financial development has a significant inhibitory effect on the urban-rural income gap. Among them,the impact of financial development efficiency is stronger than the scale of financial development. In addition,the upgrading of the industrial structure has an expanding effect on the urban-rural income gap. The increase in openness has a significant inhibitory effect on the urban-rural income gap,and social security expenditures also effectively play a role in narrowing the urban-rural income gap. Besides,the urban-rural income gap itself has a significant lag effect.
