边疆民族地区治理在本质上是一类较为特殊的系统型地方治理,其特殊性表征为国家治理与地方治理的复合性、特定的民族事务治理与一般性地方事务治理的交叉性、全球治理与区域治理的融汇性。由于边疆民族地区治理的特殊性、单一制国家结构形式、政府职责配置等中央与地方关系等各种原因,使得边疆民族地区治理存在着显著的国家治理要素,包括治理理念层面中央顶层设计与地方性知识相互融入,治理结构层面中央权责配置与地方权责配置相互协调,治理过程层面中央决策领导与地方执行实施相互结合。边疆民族地区治理需兼顾地方性治理目标和国家性治理目标的“五维双层结构式”目标,涵括政治维度上维护边疆稳定与国家安全、社会维度上深化民族和谐与社会整合、经济维度上推动兴边富民与区域协调、文化维度上实现文化交融与文化自信、生态维度上建设生态屏障与美丽中国。在国家治理视域下,应通过完善分工协同机制、信息共享机制、资源分配机制和纠偏监督机制,不断协调优化国家治理与边疆民族地区治理的关系,推动边疆民族地区治理走向现代化。
