文章以经济极化、循环累积因果等相关理论,选择广西壮族自治区作为案例,探讨我国民族地区在经济发展过程中,追求省会城市极化发展带来的效率与现实中区域–族际间发展不均衡之间的矛盾。通过将政策规划与现实发展数据对照,可以观察到,民族地区如果要强化省会城市的经济地位,在很长一段时间里,虹吸周边资源的回波效应要强于带动周边发展的扩散效应。由于少数民族群体向省会城市集聚的动机、能力偏弱,这种发展战略将会加剧产生新一轮的区域–族际发展失衡风险。为此,在发挥市场机制对资源的配置的决定性作用同时,通过积极的公共政策与公共服务,消除区域–族际间各类发展不均衡现象,引导人口、资源、财富向省会城市同步集聚,使作为民族地区的广西在获得极化发展效率的同时,进一步促进族际群体间发展公平。Based on the theories of economic polarization and circular cumulative causality, this paper selects Guangxi Zhuang Autonomous Region as a case study to explore the contradiction between the efficiency brought by the polarization development of provincial capital cities and the unbalanced development between regions and ethnic groups in the process of economic development in China’s ethnic areas. By comparing the policy planning with the actual development data, it can be observed that if the ethnic areas want to strengthen the economic status of the capital city, in a long period of time, the echo effect of siphoning the surrounding resources is stronger than the diffusion effect of driving the surrounding development. Due to the weak motivation and ability of ethnic minority groups to gather in capital cities, this development strategy will aggravate the risk of a new round of regional and inter-ethnic development imbalance. To this end, while giving full play to the decisive role of the market mechanism in the allocation of resources, through active public po
