[摘 要]以成渝经济区147个县域为研究单元,运用空间相关性分析方法,在Eviews、OpenGeoDa和ArcGIS软件的支持下,从数值分布与空间变化特征角度研究成渝经济区2000—2015年县域经济空间格局演化。研究发现,成渝经济区内空间集聚程度呈整体下降趋势,局部空间相互关系明显,经济增长空间格局稳中有变。进一步分析发现,资本、产业结构、对外开放程度因素对成渝经济区县域经济空间差异影响明显。为缩小成渝经济区县域经济发展差异,实现经济区均衡发展,应在优化空间格局、完善基础设施建设、调整产业结构、提升对外开放程度等方面采取相关对策。

Abstract:Taking 147 counties of Cheng-Yu economic zone as the research unit, and using the method of spatial correlation analysis to study the spatial pattern evolution of the county economy in Cheng-Yu economic zone between 2000 and 2015 from the perspective of numerical distribution and spatial change characteristics. Results show that the spatial agglomeration degree of Cheng-Yu economic zone presents a trend of overall downward, the relationship between the local spaces is obvious, and the spatial pattern of economic growth has renovated in steadiness. Further analysis reveals that capital, industrial structure and the degree of opening to the outside world have obvious influence on the economic space difference between the counties in Cheng-Yu economic zone. In order to reduce the difference between the counties of Cheng-Yu economic region and to realize the balanced development of economic zone, we propose to take countermeasures in optimizing the spatial structure, improving the infrastructure construction, readjusting the industrial structure and enhancing the degree of opening to the outside world.

Key words:county economy; the evolution of spatial pattern; Cheng-Yu economic zone

县域经济是国民经济体系的基本单元、基础层次和基本细胞[1]。摸清县域经济发展概况,对于制定科学的区域经济发展政策有着重要的指导作用。经济发展的过程是一个区域差异变化的过程[2]。对区域经济差异的空间格局探索是研究区域经济差异的关键[3]。目前,对发达地区空间差异的研究较多,但对于欠发达地区的研究比较少。成渝经济区作为西部唯一具备突破省市界限、在更大范围内优化配置资源的地区,是西部地区自然和经济发展条件良好及人口和城市密度最高的区域,是国家推动西部大开发战略的重要引擎,是提升内陆开放水平、增强国家综合实力的重要支撑,在我国经济社会发展中具有重要的战略地位[2,4,5]。……
