Based on the scope economic theory of “resource curse” and industrial clusters, the scale of sugar cluster is calculated by the outputs of sugarcane and sugar while the scale benefit of sugar cluster is measured by the productivity ( rate of sugar production), sales output ratio, industrial output value as well as profit margin. Positive analysis of the scale merit of sugar clusters in resource - rich area of southwestern Guangxi is conducted according to related statistics of Chongzuo City. And the primary problems of sugar clusters are pointed out. The profit created by sugar for the sugar industry in Chongzuo City has already been near capacity. The sugar industry is big but not strong. With much governmental interfernce, there is no effective connections and inadequte competitive forces among subjects of the clusters. The extention of industrial chain is limited. Therefore, measures for developing sugar clusters in resource - rich area of southwestern Guangxi are proposed. Industrial structure is to be adjusted to improve the sugarcane cultivation techniques. The industrial chain should be extended to increase the economic benefits of sugar industry. Industrial support is to be strengthened and capital output for sicence and technology increased. Price regualtion fund of grain sugar is to be established with coordination with the superior region. The transforming speed of savings to investment should be quickened to evade “resource curse”.%基于"资源诅咒"和产业集群的规模经济理论,以糖蔗产量、成品糖产量衡量糖业集群的规模,以产率(出糖率)、产销率和工业产值以及利润率衡量糖产业集群的规模效应,根据崇左市相关数据,对桂西南资源富集区糖业集群的规模效益进行了实证分析.指出了糖业集群存在的主要问题:成品糖为崇左市糖业创造的利润空间已经接近极限;产业大而不强;政府干预多,集群主体之间缺乏有效的联系,竞争力度明显不足;产业链延伸长度有限.提出了桂西南资源富集区糖业集群发展的措施:调整结构,提高甘蔗种植技术;做长产业链,提高糖业经济效益;加大产业扶持力度,增加科技资金投入;协调上级区域,建立食糖价格调节基金;加快储蓄向投资转化的速度,规避"资源诅咒".
