【摘要】 基于县(区)尺度,选取16项指标衡量东北省际边界区经济发展水平,运用均方差决策、变异系数和ESDA-GIS方法分析了2000—2015年东北省际边界区经济差异的时空特征、趋势及形成机理.结果表明:(1)东北省际边界区经济发展水平相似的县域在空间上两极分化并集聚的态势与经济差异时间演化趋势一致,空间极化成为该区域空间结构演化的主要趋势;(2)HH型县域呈现不断向黑吉交界的东部地区集聚的趋势,而LL型呈现不断向辽西北和内蒙古东南部集聚的趋势,东西部差异成为东北省际边界区经济差异的主要表征;(3)自然区位、经济条件、政府导向、空间作用和边界阻隔是东北省际边界区经济差异变动的形成机理.更多还原

【Abstract】 The economic difference between provinces and border areas is a new field in the study of regional economic differences.Based on the county(district)scale,this paper selects 16 indicators to measure the economic development level of the inter-provincial border areas in Northeast China,and uses the mean square error decision,coefficient of variation and ESDA-GIS method to analyze the temporal and spatial characteristics of the economic differences between the provinces in Northeast China from 2000 to 2015.Trend and formation mechanism.The results show that:(1)The county with similar development level in the inter-provincial border areas of Northeast China is spatially polarized and agglomerated,which is basically consistent with the evolution trend of economic differences.Spatial polarization becomes the main trend of spatial structure evolution in the region.(2)HH-type county presents continuously the trend of gathering in the eastern part of the border of Heiji,while the LL type shows a trend of accumulating in northwestern Liaoning and southeastern Inner Mongolia,and the difference between the east and the west becomes the main indicator of economic differences in the inter-provincial border areas of the northeast.(3)natural location,economic conditions,government orientation the spatial role and boundary barrier are the formation mechanisms of economic differences in the inter-provincial border areas of Northeast China.更多还原
