The private sector is a major contributor to economic growth, employment creation, and poverty reduction. The private sector plays a significant role in sustainable development. Thus, the development of entrepreneurship and a broader set of relevant productive capacities and the redeployment of resources into activities with higher productivity lie at the heart of self-sustaining and lasting economic growth. As governments establish stable macroeconomic environments, enact policies to facilitate economic diversification, and have primary responsibility for education, infrastructure and other public goods, the private sector plays a role in enhancing productive capacities and entrepreneurship. However, for the private sector to achieve set objectives there is the need for proper control and regulation via the implementation of government policies. This also applies to private telecommunications companies. The main focus of the study is to explore the impact of government policies on private enterprises performance; focusing on GSM companies in Nigeria.
