Answer :
The major factors that influenced the development of the colonies was the production of major crops like cotton. The production and export of cotton to the northern colonies as well as Europe drove the southern economy for decades, even up to the Civil War. In addition this economic development was made possible by the abundance of slave labor that lowered costs and led to high levels of production.
One factor that influenced the development of the Southern Colonies is transportation because Southern Colonies have cash crops but no transportation to transport rice, indigo, and other cash crops to markets and people. The other major factor could be slavery because they will be having less profit as there is less population and more slaves in the Southern Colonies.
