Two sets of competing theories have been proposed to explain the exist
ence of franchising; one set based on resource constraints and another
on incentives issues. As individual franchise systems mature, these t
heories predict different patterns in the evolution of the mix of fran
chised and company-owned outlets. In this paper, we report the results
of an empirical study of franchise system evolution. The findings gen
erally support the incentives-based rationale for franchising, but the
y also support a modified resource constraint theory, one which recogn
izes the synergistic effects of dual distribution.
