A population ecology of network domains
基于74个目的导向网络的长时段数据，检验人口生态理论对网络域动态的解释力，为公共和慈善项目提供警示。
Purpose-oriented networks (PONs) are a crucial and prevalent forum for addressing complex public issues. Using a longitudinal bipartite dataset of 74 PONs nested in three different geographic areas, we test a series of hypotheses, based in population ecology theories, concerning the impact of domain-level dynamics on network-level outcomes. Findings offer substantial support for, and insight into, the relevance of population-level dynamics in explaining organizational, network, and domain-level changes over time. Findings further offer practical insight and a cautionary tale for public and philanthropic initiatives that incentivize or mandate the formation of new PONs in a network domain.
