I believe it is because if New England started a manufacturing industry, it could result in self-sufficient colonies, and England also wouldn't make money off of them.
Ex.
a) south produces raw material => sent to North => Raw materials processed and sold
b) south produces raw material => sent to England => England processes raw materials => can be sold to the colonies and  other countries 

Answer:

England discouraged the development of manufacturing in New England colonies because it would influence the colonies becoming self-sufficient, which would gradually lead it into self-supporting colonies. By allowing the colonies into manufacturing goods would bring crises in the British economy. New England colonies supplied raw materials to England, the raw material was manufactured in England and were sold in colonies for the profit as well as to make these colonies their dependent.
