本文的目的在于阐明通过影响力投资获得资金的印度企业的要素。为此，本文考察了印度影响投资业界团体Impact Investors Council (IIC)的组织案例，我们还对亚洲最大的印度投资公司Aavishkaar Capital的相关人士进行了半结构化采访调查。结果显示，在利用印度的影响投资方面，除了社会价值(为解决社会问题而实施商业)之外，还包括经济价值(投资公司能够判断商业可持续性的商业模式、经营者的魅力;商业环境变化应对能力、沟通能力、数据活用能力)的高水准获得也很重要，虽然这些价值的获得有难度，但是对于包括中小微企业在内的影响导向型企业(影响企业)来说，影响力投资可以成为一种融资手段。
