基于ESDA的青海省县域经济差异时空分析

采用探索性空间数据分析的方法,利用2005—2014年的青海省县域人均GDP数据,从时空的角度对青海省县域经济差异进行分析。分析结果表明:(1)青海省县域经济发展水平差异较大,且有进一步加大的趋势,青海西北部经济发展水平较高。(2)青海省县域经济具有显著的空间正相关关系,且这种关系在加强,县域经济联系愈加紧密。(3)青海省县域经济发展空间集聚作用明显,逐渐形成了"HH"和"LL"的空间分布格局。"HH"的聚集范围为海西蒙古族藏族自治州、德令哈市等的海西区域,"LL"的聚集范围为玉树县、达日县等的海南区域。然后,从经济发展基础、经济发展区位、空间邻近效应分析影响青海省县域经济差异的原因,并结合空间特征提出相应建议。

Spatio-temporal analysis of inter-county economic differences in Qinghai Province based on ESDA

From the perspective of spatio-temporal, taking the inter-counties of Qinghai as the study object and per capita GDP as the measuring indicator, this paper analyzes the spatial-temporal pattern of economic differences in Qinghai Province from 2005-2014 by way of ESDA.The results show that:the development level of inter-county economy is different in Qinghai province, and there is a trend of further increase.Besides, the northwest of Qinghai is relatively high;the inter-county economy has a significant positive correlation in Qinghai province.With the strengthening of the relationship, the county economic ties become more and more closely;the spatial agglomeration of county economic development in Qinghai Province is obvious, and gradually forms the spatial distribution pattern of "HH" and "LL"."HH" range of aggregation for the Haixi Mongolian Tibetan Autonomous Prefecture, Deilingha county of Haixi region, "LL" range of aggregation for Yushu county, Dari county and other areas of Hainan.Then, based on the economic development, the location of economic development, spatial proximity effect analysis of the reasons for the economic differences in Qinghai Province, this paper puts forward the corresponding recommendations based on spatial characteristics.
