摘要
西藏是全国唯一的省级集中连片特困地区。文章采用2000—2017年西藏县域综合实力指标面板数据,运用主成分分析和空间自相关分析等方法和相关软件,分析西藏县域综合实力的时空演化特征。结果表明:西藏县域间综合实力差距有逐渐拉大的趋势,且自2004年开始综合实力空间分布表现出较显著的空间正相关性(空间集聚)。局部空间自相关分析结果显示,高—高聚集和低—低聚集的二元分布是西藏县域空间分布的显著特征,且已初步形成以城关区和巴宜区两个地区强县为主导的"强县经济圈"。根据西藏县域时空分异特征,探讨西藏后续发展的政策思路及建议。
The Tibet Autonomous Region is the only provincial-level contiguous destitute area in China.This paper utilizes the panel data of counties in Tibet Autonomous Region from 2000 to 2017,and analyzes the spatio-temporal evolution features of its comprehensive strength applying the methods of principal component analysis and spatial autocorrelation analysis as well as relevant tools.The results show that the gap of comprehensive strength among the Tibetan counties is gradually widening.The spatial distribution of comprehensive strength of each county shows positive spatial autocorrelation(spatial agglomeration).In terms of local spatial autocorrelation,the results show that the binary distribution of high-high aggregation and low-low aggregation is a prominent feature of the spatial distribution of the Tibetan counties.The’strong-economic circle’dominated by two strong counties(Chengguan District and Bayi District)has been initially formed.Based on the features of the spatio-temporal distribution in the Tibet Autonomous Region,the policy ideas and suggestions for the follow-up development of the Tibet Autonomous Region are discussed.
