This paper presents the results of theoretical research regarding issues related to the formation of organisational knowledge at modern enterprises. This organisational knowledge has some peculiarities, as discussed in the paper. The emergence of organisational knowledge and its collective character is determined in many ways by internal communications.

The main purpose of the research is to identify types of internal communication strategies as a basis of organisational knowledge formation at enterprises.

Four types of enterprise internal communication strategies defining the peculiarities of exchange and spread of knowledge among employees are set out: the supporting formally-documentary internal communication strategy, the network information-technological internal communication strategy, the engaging socially oriented internal communication strategy and the integrative knowledge-producing internal communication strategy.

The research results confirmed that there are different approaches to defining the factors contributing to knowledge sharing. When working out measures to manage internal organisational communications at enterprises it is reasonable to single out two aspects: socio-psychological and informational-techno- logical. The author suggests management arrangements to provide the transition from other types of internal communication strategies to the integrative knowledge-producing strategy
