Six Factors That Affect Economic Growth
1. Natural Resources. The discovery of more natural resources like oil, or mineral deposits may boost economic growth as this shifts or increases the country's Production Possibility Curve.
2. Physical Capital or Infrastructure.
3. Population or Labor.
4. Human Capital.
5. Technology.
6. Law.


To the best of my knowledge, these six issues are all important!
However, the deepest is still the issue of technological innovation. Slow technology development will stagnate for the economy!
