How to Achieve Large-Scale Social Impact
结合社会创业与系统理论，识别出使命驱动型组织实现大规模社会影响的两条主要路径和四种具体策略，并通过四个案例加以说明。
The authors combine scholarship from social entrepreneurship and systems literature to identify two dominant pathways used by mission-driven organizations to achieve large-scale social impact. The scaling impact approach expands the reach or depth of a proven solution by unit-level expansion. The impact at scale approach, by contrast, works at a population level to address the problem at scale. Four original case studies illustrate how organizations translate these approaches into strategies to address large-scale social problems. The four strategies are: (1) expanding through scale, (2) expanding through scope, (3) growing through systems optimization, and (4) growing through systems reinvention.
