What were the economic developments of the English colonies prior to 1700?

I assume you mean the English colonies in America.
Economic development was a major cause of the divisions North and South which would lead
to the Civil War 175 years later. Therefore in discussing economic development, it is
important that one consider geographic factors.

The
Southern Colonies enjoyed warm climate, deep fertile soils, but few natural harbors. As
a result, their economy was primarily agricultural. Large plantations developed which
grew "staple crops," primarily tobacco; but South Carolina primarily grew rice and
indigo. Since a tremendous amount of labor was required, slavery became an important
economic development in the South.

The Northern colonies
had thin, rocky soil and good harbors. As a result, although there was some farming, a
greater emphasis was placed on shipping and shipbuilding. It was for this reason that
the North industrialized much more quickly than the South; and also why Slavery never
gained a significant foothold in the North.

The "Middle
Colonies," primarily Pennsylvania, Maryland and New York engaged in some farming, but
primarily wheat and other grains. Large scale plantations as seen in the South did not
develop; but neither did extensive industry.
