First, this paper discusses the definition of DCCC, analyzes its intrinsic structure, and uses fitness landscape to analyze interactions between elements of DCCC and relationships between elements and whole of DCCC in detail. Then this paper explores the increasing mechanism of DCCC. A theoretical framework is presented to explain the increasing mechanism of DCCC. Finally, a model of competence substitution in the evolution of DCCC is provided. The major contributions of this paper are ： （ 1 ） DCCC is a complex adaptive system which is constituted of such actors as humans in firms and such elements as strategic competence, organizational competence, marketing competence, and technological competence. （2） The fitness landscape shows DCCC has a characteristic of ＂part is all＂. （3） The conflict between shadow system and legitimate system drives a firm into creating space. The harmony of shadow system and legitimate system drives the realization of archetype, and results in knowledge creating, which in turn drives the evolution of DCCC. （4） The model of competence substitution in the evolution of DCCC--Conditioned emergence model could be used in management of competence substitution process. It includes three stages： conditions for competence substitution, creating conditions states far from existing equilibrium, and managing feedback
