We study the cluster-shell competition in carbon isotopes. Two parameters are introduced for the 12C core to characterize the transition from a cluster state to a shell-model state as a measure of the cluster-shell competition: one expresses the relative distance between clusters and the other does the dissolution of one of the clusters. We show the energy curves as functions of these parameters. The calculation is performed by combining the simplified modeling of cluster-shell competition for the 12C core and AMD triple-S. As the neutron number increases, the - distance becomes smaller; on the contrary, the dissolution of clusters is enhanced. The origins of the anomalously small B(E2) value of 16C are discussed from cluster-shell competition point of view, and the appearance of pure cluster state around the 10 MeV region is suggested.
