摘要
采用ESDA的方法,运用ArcGIS10.0和GeoDa095i软件,选取1980年、1990年、2000年和2010年4个时间断面分析了自改革开放以来内蒙古县域经济空间格局演化的过程。结果表明:①改革开放以来,内蒙古县域经济空间格局和经济增长空间格局都发生了巨大的变化,其热点区都由蒙东地区跃迁到蒙中和蒙西地区,蒙中"金三角"地区代替蒙东成为内蒙古经济发展的增长极,蒙东地区则变为经济冷点区。②县域经济空间格局和经济增长空间格局都有明显的空间自相关性,且经济空间格局的空间自相关性越来越大。③内蒙古县域经济形成了经济水平相似(热点区、冷点区)的集中连片区,内蒙古东、中、西部的经济差异越来越大。影响内蒙古县域经济空间格局演化的因素可以可分资源、历史文化、区位等内部基础性因素,以及市场、政策等外部驱动型因素。
Regional economic disparity is a universal phenomenon in regional economic development. To some extent the gap may promote reasonable competition among regions, but if the regional economic difference is too large, it may cause disorder and social unrest. Endowed with a special location, natural resources and eth- nic composition, Inner Mongolia＇ s economic development plays a significant role in the socio-economic devel- opment and prosperity of the whole-region as well as of the country. It has gained tremendous economic devel- opment in recent years, the economic growth rate ranked first for 9 consecutive years in China since 2002. However, few studies have been made about Inner Mongolia, especially on the spatial pattern of economic de- velopment and growth rate at tiny spatial scales. This article analyzed the regional economic disparities of In- ner Mongolia at the county level with panel data from 1980 to 2010 with exploratory spatial data analysis methods, of Moran＇ s I and Getis-Ord G＊,, whereby the significance of spatial interactions and geographical lo- cation was investigated. With the application of ArcGIS10.0 and GeoDa095i, the spatial patterns of per capita GDP and economic growth rate of counties over the 30 years were analyzed. It was found that： 1） The overall spatial patterns of economic development level and growth speed of Inner Mongolia at the county level have tremendously changed. The hot spots moved from eastern regions to central and western regions. The golden triangle region composed by Hohhot, Baotou, and Ordos has become the economic growth pole of Inner Mon- golia. 2） Both the economic development level and the growth rate exhibited significant spatial autocorrela- tion. While that of the former has become increasingly obvious, that of the latter has increased and then de- creased. It revealed that the accumulating of the economic growth rate was slowing down. 3） The development of Inner Mongolia in recent years has fortified the differentiation of three discontinuous economic blocks： the eastern block was less developed, and the western and central blocks became developed. As a result, the region- al economic disparities enlarged between the three blocks. The article also analyzed the influencing factors of the evolvement, from perspectives of internal conditions including resources, history and culture, location, and external driving forces such as market and policies.
