【摘要】 在精准扶贫的基础上,十九大指出要坚持大扶贫格局。四省藏区作为全国14个集中连片特困地区的脱贫攻坚主战场之一,为寻找其经济发展落后的症结所在,本文选择其中的72个县域单元为研究对象,运用空间自相关分析和地理加权回归分析方法,分析其县域经济空间差异的演变和影响因素。结果表明:2005—2016年间县域经济发展呈明显的空间集聚现象且各县域间相关性有增强趋势,四省藏区县域经济整体上呈现出"点—线—片"分异特征,发展水平较高的县域向邻边县域缓慢扩散,发展水平较低的县域空间集聚性不断增强且向东北蔓延;从影响因素来看,由西北向东南,影响因素强度依次为人均储蓄余额、人均财政支出、第二产业和固定资产投资。更多还原

【Abstract】 Based on the development of the targeted poverty alleviation,the 19 th national congress of the communist party of China indicates that China would insist the poverty alleviation strategy. In order to discover the causes of the slow economic development in Tibetan areas of four provinces,one of 14 concentrated contiguous areas of extreme poverty in China,72 counties are used to analyze the evolution and impact factors of the county spatial economic disparity by using the spatial autocorrelation and geographically weighted regression analysis method. The results show as follows: The spatial agglomeration and positive correlation of the county economic development are significantly strengthened in the Tibetan areas of four provinces during 2005—2016,showing a "point-line-patch"structure characteristics. The counties with higher development level spread slowly to neighboring counties,while counties with lower development level show the enhanced spatial agglomeration and spread to northeast. Regarding the strength of the impact factors,the per capita-savings,per capita fiscal expenditure,secondary industry,and fixed asset investment,decreased successively from northwest to southeast in the Tibetan areas of four provinces.更多还原
