Complementarity in the recreational cluster as a factor ensuring the integrity of recreational services

The complementarity of goods is the property of goods or services to satisfy needs only in combination with each other. A recreational cluster can ensure the complexity of recreational services only if there is complementarity of the activities of the elements of the cluster structure among themselves, as well as in working with municipal and other external structures. The degree of complementarity between different members of the cluster is non-invariant with respect to the direction of complementarity.
