Assessment Of Industrial Policies In Ghana: A Case Study On The Current Policy Of One District One Factory Policy (1d1f), Ama Nyamekye Obenewa Otoo

Masters Theses

Industrialization has been the weakest link in Ghana’s economic development efforts. Import-substitution industrialization policy of the 1960s-1980s and the outward liberalized industrialization policy of 1990-2020 (Vision 2020), have failed to achieve the goals of industrialization. This is due to several reasons including the selfish interests of these political leaders and lack of technological advancement. In 2017, the elected New Patriotic Party (NPP), announced a new industrialization policy known as “one district, one factory" (1D1F), which was a political campaign promise to realign industrial strategies. The goal of this policy is to ensure that industries are spread equitably among the country's …
