Revisiting the Density Dependence Model: Innovation Ecology in the Greater Los Angeles Area and Silicon Valley

• In Event: Organizational Communication Research Escalator - Extended Session (Part 1)

Abstract

This study applies the community ecology perspective to revisit the density dependence model, by analyzing how interpopulation links influence the effect of density on population growth. It expands the focus from populations to the organizational community. Interpopulational networks are conceptualized as additional resources each organization possesses to move beyond the limited resources available within their own environmental spaces. With data collected from AngelList, this study examines the funding patterns for two industries (tech startups and media startups) in the Greater Los Angeles Area and Silicon Valley. It contributes to the development of density dependence model by introducing population connectivity in an organizational community as a predictor. Through the empirical investigation of startup funding ecosystems, this study provides practical implications on how to sustain innovation efforts in both areas.
