文章在对民族地区人口迁移与区域经济差异互动机理及空间格局演化进行分析的基础上,结合实地调查资料,探讨了民族地区人口迁移与区域经济差异的空间联动效应。结果显示,民族地区人口迁移与区域经济差异呈现一定的空间集聚性,二者空间关联也从相离走向相合;民族地区经济差异的逐渐扩大与迁移动力不足源于宗教文化与市场文化的难以调适,也与对口支援工作的“重量不重质”、交通等基础设施的严重缺位、城乡二元结构稳固及人力资本存量不足有关。政府不合理地干预市场导致民族地区经济发展存在偏离地区比较优势的倾向,削弱了地区经济整体实力并扩大了区域差异;民族高度聚集区居民幸福感高涨是其“固守本土”的主要内因,而无上限的政府扶持则放大了民族地区人口的迁移惰性;城镇化进程的不合理使其在吸引剩余劳动力、缩小区域经济差异上表现出边际收益递减效应。文章针对这些问题提出了相应政策建议。 Based on the analysis of the interactive mechanism and the evolution of spatial pattern between population migration and regional economic disparity in ethnic minority areas, the paper explores the spatial linkage effect between population migration and regional economic disparity in ethnic minority areas based on field survey data. The results show that there is a certain degree of spatial agglomeration between population migration and regional economic disparity in ethnic minority areas, and the spatial correlation between the two also converges from phase to phase. The gradual expansion of economic disparity in ethnic areas and the lack of motivation for migration stem from the difficult adaptation of religious culture and market culture But also related to the serious lack of infrastructure such as transportation and infrastructure, the stable urban-rural dual structure and the shortage of human capital stock. The unreasonable intervention of the government in the market led to the tendency of deviating from the comparative advantage in the regional economic development, weakening the overall strength of the regional economy and widening the regional disparity. The high level of well-being of residents in the highly populated areas was the major internal cause of “sticking to the local community” However, the unreasonable government support from the government has enlarged the inertia of population migration in the ethnic minority areas. The unreasonable urbanization process has shown the diminishing marginal returns in attracting surplus labor and narrowing the regional economic disparity. The article puts forward corresponding policy suggestions on these issues.
