关中—天水经济区县域经济发展空间差异及影响因素分析

Study on the Spatial Differences and Influencing Factor of County Economic Strength in Guanzhong-Tianshui Economic Zone

以关中—天水经济区为研究对象,选取2010年县域经济发展水平的14个指标,运用主成分分析相关数据衡量经济区经济综合实力,研究关中—天水经济区区域经济差异及分布特征。通过Moran指标对经济区经济综合实力进行测定,结果表示,经济区存在较明显的空间集聚性和空间相关性,通过Moran散点图及LISA揭示出西咸地区、宝鸡、铜川为经济综合实力的高值地区,而经济区的西部、中部及东南部为经济发展的落后地区。通过对2010年经济综合实力空间计量回归分析,发现规模以上工业总产值、固定资产投资总额、人均地方财政支出及城镇化水平对经济综合实力有显著影响,并进一步检验和计算空间相关性的作用强度。

Based on the county data of relative economic indexs in Guanzhong-Tianshui economic zone, this paper calculates the general score of county economic level by using SPSS, and analyzes the spatial differ- ences of county economic level in the zone. Through the Moran index to calculate aggregation degree, the results show that the zone has obvious spatial agglomeration and spatial correlation. Moran scattered point diagram and LISA reveals that Xi＇an--Xianyang area, Baoji, Tongehuan are the area which economic indexs are high. But the west, middle,and the southwest are the undeveloped areas. Through analyzing the eco- nomic indexs spatial econometric regression of 2010, it found that Gross output value of industrial above designated size, total fixed asset investment,local fiscal expenditure per capita and urbanization level have significant influences, and further testing and calculation of the spatial correlation function intensity.
