简介:在Myanmar,正式金融机构不提供uncollateralized学分。在贫穷线下面的农村unbanked与高利率正在取决于非正式的放债者。私人代理处合作一起仅仅是没有担保并且与低利率,在Myanmar提供学分给unbanked的一个microfinance机构。unbanked的一半是不能的因为信息贡献的软弱和microfinance机构的严格的法律政策,从microfinance机构借贷款。因此,这研究的目的是构造一个系统由在microfinance机构的当前的系统减少障碍改进在microfinance机构和unbanked之间的关系。法律政策作为这研究和i的创见从本地unbanked的视觉被学习--系统方法论被使用完成研究。当前的系统包括信息贡献,贷款和法律政策。当前的系统仅仅是在microfinance机构和unbanked之间的一种关系。当十个障碍发生在当前的系统时,unbanked不能来临到microfinance机构。包括四个分系统的一个存取系统被开发取决于收集了想法解决这些障碍并且打算改进在microfinance机构和unbanked之间的关系。
