武陵山片区县域经济空间格局演化与优化对策

Evolution and Mechanism of Regional Development of Wuling Mountainous Area

以我国新时期区域发展与扶贫攻坚先行先试区武陵山片区为例,构建综合指标,利用空间统计分析方法分析该区域县域经济空间格局演化特征,归纳了其影响因素和形成机制。结果表明,武陵山片区区域经济发展水平整体在逐步提升,经济重心略偏北有弱集聚性,空间差距在缩小。不同水平和发展速度的区县等级数量分布由"纺缍型"变为"金字塔型";空间上优势县呈"斑块"状离散分布,劣势县呈"连片"状相对集中分布,空间相关性不显著,溢出效应不明显。空间格局的变化主要受自然地理条件、资源开发、交通区位、市场发育、政策等因素及其相互作用的影响。文章最后提出优化发展对策。

Concentrated continuous poor areas are typical regions affecting regional coordinated development of China. They are commonly remote, impoverished, ecologically fragile, ethnical, and with low level of human capital. So it is of great significance to recognize evolutional patterns of spatial structure of regional economic development and its drivers. This paper analyzes evolutional characteristics of economic spatial pattern, its main impact factors and formation mechanism at the county level in Wulingshan mountainous areas, through a approach of comprehensive index and spatial statistics. The results show that overall economic development level in this areas improves gradually with weak spatial agglomeration. The centre of economic gravity locates in slightly north and spatial difference is becoming small. The rank-quantity structure of counties with different development level and speed changes from ＂spindle＂ to ＂pyramid＂. The distribution of advantageous counties disperse as ＂patches＂, while disadvantage counties relatively concentrate together. The spatial autocorrelation of counties is weak at the previous time, and finally spatial spillover effect is not obvious. Natural geographical conditions, resources endowment and development, location and traffic conditions, market development level and poverty alleviation policy are the key drivers of economic spatial pattern changes of the areas. Finally, this paper put forward some countermeasures for optimizing the development patterns in the areas.
