胶济铁路交通经济带县域经济时空关联性研究

The Correlation Research of County Economic Spatio-temporal to Traffic Economic Belt Along Jiaoji Railway

以胶济铁路辐射120km范围内的县域(含县、县级市、市辖区)为研究单元,运用标准差、变异系数与空间自相关方法,分析胶济铁路交通经济带2000-2013年县域经济的时间演化趋势与空间格局分异特征。结果表明:时间序列上,新世纪胶济铁路交通经济带县域经济快速发展,县域经济绝对差异显著扩大,相对差异明显缩小,两极分化现象突出;空间格局上,胶济铁路交通经济带县域经济具有明显的空间自相关特性,经济发达区主要集中于青岛市与淄博市的部分市辖区及其周边县域,经济落后区主要集中于鲁中及鲁西地区。

Taking the Jiaoji Railway radiation within 120 km counties（including counties, county-level cities and municipal districts） as the study object. Using Standard Deviation, Coefficient of Variation and Spatial Autocorrelation to analyze changes of the county economy and spatial variation characters from 2000 to2013. The result indicated： in the 21 st century, the county economy growing rapidly and absolute differences expand significantly.Conversely, the relative differences reduced significantly and polarization outstanding. On the space, county economy we chose the study area has a significant spatial autocorrelation characteristics. Economically developed areas are mainly concentrated in the surrounding county of Qingdao and Zibo. Then underdeveloped areas are mainly distributed in the central and western counties.
