Natural resources are a factor in the process of growth,which might expand the frontier of production theoretically.But currently,the phenomenon of"resource curse" is a strong tendency.Regions with abundant resources usually have slower growth than those lack of resources.Natural resource abundant countries constitute both growth losers and growth winners,and the main difference between the success cases and the cases of failure lays in the quality of institutions.With grabber friendly institutions more natural resources push aggregate income down,while with producer friendly institutions more natural resources increase income.
