经济不均衡增长是区域发展的一种常态。分析区域经济增长时空差异及成因,对于认识和加快落后地区的经济发展具有重要的意义。本研究在GIS技术的支持下,对黄土高原地区近20年来以县市为单元的经济增长时空分异特征进行了系统的分析。主要结论有:改革开放以来,黄土高原地区的GDP水平呈现出持续的快速增长态势。近20年来,陕北和内蒙古鄂尔多斯地区增长最为迅速;人均GDP的空间分布整体上呈现出“两高一低”的带状分布格局,且这种格局明显地受到极化增长的扰动和重塑;经济增长表现出显著的极化增长特征,且经济增长极的极化作用与增长极之间地位的调整是同时进行的;与常态化的城市产业集聚推动型经济相比,机遇性的资源开发拉动型经济对人均GDP的拉动速度更快,但可持续性较差。未来,黄土高原地区应走以中心城市带动为主,以能矿产资源开发拉动为辅,两者相互促进,共同带动整个区域经济更快、更好、更可持续地发展的道路。
Uneven economic growth is a normal development in the region. Analyzing the spatiotemporal differences and the causes of regional economic growth is of great significance for understanding and accelerating the economic development in the backward regions. With the support of GIS technology, this study systematically analyzes the spatial and temporal differentiation of economic growth in counties and cities in the Loess Plateau over the past 20 years. The main conclusions are: Since the reform and opening up, the GDP of the Loess Plateau has shown a sustained and rapid growth. In the recent 20 years, the northern part of Inner Mongolia and Erdos in Inner Mongolia have witnessed the fastest growth. The spatial distribution of per capita GDP shows a banded distribution pattern of “two highs and one low” as a whole, and this pattern has been obviously disturbed by polarization and growth. Remodeling; economic growth showed significant polarization growth characteristics, and the polarization of economic growth pole and the adjustment of the position between the growth pole at the same time; compared with the normal urban agglomeration-driven economy, the opportunity The resource-driven economy has a faster per capita GDP but less sustainable. In the future, the Loess Plateau should be dominated by central cities and supplemented by the development of mineral resources. Both should promote each other and lead the economy of the entire region to a faster, better and more sustainable development.
