Location conditions and main industrial sectors of the three major industrial zones in the United States

Northeast China is the earliest area where European immigrants arrived, and also the earliest area where American capitalism developed. China's traditional industries such as steel, machinery, automobiles and chemicals are mostly concentrated here.

The southern region used to be dominated by agriculture. Because of the cheap land price, abundant labor force and less environmental pollution, a new industrial base of petroleum, aircraft, aerospace and electronics in the United States has been formed.

The long and narrow plains and valleys along the Pacific Ocean are the concentrated areas of western industries, and emerging industries such as aerospace, electronics and information technology are developing rapidly, making it the largest high-tech industrial center in the United States.
