To bridge this gap in the literature, we adopt a computable general equilibrium model to simulate the socio-economic and environmental impacts of different iron ore resource tax reforms from an economy-wide perspective. The results show that this reform has had a limited influence on reducing the tax burden in the iron ore industry.
