Magnolia when it was founded was a cotton, farm production, and marketing town. Slowly the town grew, and in 1909 the Third District Agricultural School, subsequently known as Magnolia A&M and Southern State College, now known as Southern Arkansas University, was founded. During World War II Magnolia became a heavy manufacturing city. In 1938 oil and natural gas were discovered near the city in what was called the Magnolia Oil Field, the largest producing field by volume in the nation during the war. The city soon became a producer in steel, lumber, aluminum, bromine, rubber-coated products and fuel cells for the military.

The town's primary economic focus is heavy industrial, including Albemarle Corporation's Bromine Products Division (which has two facilities near town), Amfuel (which produces fuel cells for the military), and Sapa Group's extruded aluminum products facility. Also located in the area are several oil and brine drilling companies, many of which are locally owned, and timber companies, such as Deltic and Weyerhaeuser.
