We develop a framework to explain the underlying processes by which social entrepreneurial passion affects social innovation performance. The findings from a survey of 229 U.K.-registered Community Interest Companies indicate that social entrepreneurial passion can positively influence social innovation performance through creative solution generation capacity (CSGC). We also distinguish the moderating effects of different interorganizational network connections on the relationship between social entrepreneurial passion and CSGC. Our findings reveal that network connections with commercial firms are a stronger moderator of the relationship between social entrepreneurial passion and CSGC than network connections with other social enterprises. We discuss the theoretical and managerial implications of our findings.
