行政边界对振兴连片特困区的影响:区域增长极扩散效应的视角

How do Provincial Boundaries Account for the Revitalization of Contiguous Destitute Areas of China: An Investigation to the Diffusion Effects of Regional Growth Poles

从区域协同发展的角度出发探究连片特困区的致贫原因对于巩固拓展脱贫攻坚成果、接续推动脱贫地区发展和乡村全面振兴意义重大。以往对集中连片特困区区域协同发展的研究多为质性研究,本文用经济地理学框架,利用方差分析、脉冲响应函数和多元回归等多种方法,以罗霄山区为例探究连片特困区成因与行政边界的关系。研究发现,在大部分连片特困区内,来自不同省份县区的经济发展水平存在显著差异;周边增长极发挥扩散效应时会受到行政边界阻隔带来的负向影响。这一探索有助于理解连片特困区的致贫原因、理解不同行政单元因缺乏协同对经济扩散造成的阻碍,对于增强脱贫稳定性、推动脱贫地区乡村全面振兴具有重大意义。

It is of great significance to investigate the causes of poverty in contiguous destitute areas from the perspective of regional coordinated development. Previous research on this issue are mostly qualitative studies, while this paper applies the framework of economic geography, and uses analysis of variance, impulse response functions along with linear regression to research on the relationship between causes of contiguous destitute areas and their internal provincial boundaries, taking Luoxiao mountainous area as an exemplar. Main conclusions reveal that, counties of the same contiguous destitute area but from different provinces exhibit significant differences on economic development, and provincial boundaries exert negative influences on diffusion effects induced by nearby growth poles. This study enhances our understanding on how lack of coordination among distinctive administrative units undermines economic diffusion, and indicates in-depth causality of why contiguous destitute areas exist, which is of great significance for poverty alleviation.
