There are several differences between policy networks and epistemic communities. The policy networks do not reflect the same degree of coherence as epistemic communities do. Policy networks are clusters and have larger groups, while epistemic communities are a subset of policy networks. Policy networks’ membership fluctuates. Although they have different values, they are tied together by their interdependency. Power and resources are distributed unequally in policy networks. However, epistemic communities are more stable, and they consist of a smaller number of members who share same values (Carayannis, et.al., 2012: 132-133).
