民族地区教育财政支出减贫效应的空间溢出与门槛特征——基于新疆2001-2015年的面板数据分析
Spatial Spillover and Threshold Characteristics of Poverty Reduction Effect of Educational Expenditure in Ethnic Minority Areas —An Analysis of Panel Data in Xinjiang from 2001 to 2015

全国贫困人口多集中于民族地区、边疆地区、革命老区, 民族地区扶贫一直是我国扶贫工作的重点及难点, 脱贫攻坚是决胜全面小康的现实需求更是战略举措。研究基于2001-2015年的地区级面板数据, 利用空间面板回归和门槛面板回归, 考察民族地区教育财政支出与减缓贫困间的非线性空间联系, 估计了教育财政支出减缓贫困中的空间溢出效应, 并探讨了减贫过程中的门槛特征, 稳固民族地区可持续减贫的理念。研究发现:教育财政支出对于贫困减缓具有空间溢出效应, 并呈现出非线性特征, 说明了教育财政支出强度与贫困发生率在空间上非均衡分布的原因; 各地区教育财政支出对于减贫的作用差异显著, 存在门槛效应。
The poverty-stricken population in China is concentrated in the minority areas, the border areas, the old revolutionary areas, and the poverty alleviation in the ethnic areas has always been the focus and difficulty of poverty alleviation work in China. It is the strategic action to perfect the well-off society. Based on the regional panel data between 2001 and 2015, this paper uses spatial panel regression and threshold panel regression to study the spatial link between educational expenditure and poverty alleviation in minority areas, and estimates the spatial spillover effect of poverty alleviation in education expenditure, and explores the threshold characteristics of poverty reduction process and the concept of sustainable poverty reduction in ethnic areas. It is found that educational expenditure has a spatial spillover effect on poverty alleviation and shows a non-linear characteristic, which shows the reasons for the uneven distribution of the expenditure intensity of education and the incidence of poverty. The effect of education expenditure on poverty reduction in each region is significant and there is a threshold effect
