Abstract
The adoption of industrial machinery fleets in Ethiopia has been limited due to various infrastructural challenges and financial constraints. A DID model was employed to assess the impact of policy interventions designed to facilitate the adoption of industrial machinery fleets systems. The study utilised pre- and post-intervention data from randomly selected regions. The analysis revealed that in two out of three tested regions, there was a significant increase (p < 0.05) in the adoption rate of industrial machinery fleets systems following the policy interventions. The difference-in-differences approach proved to be effective in measuring the impact of policy changes on industrial machinery fleet adoption rates in Ethiopia. Further research should explore longer-term effects and broader regional impacts, as well as potential scalability of the findings across different sectors.
