According to the city's 2012 Major Employers in Torrance Report, the city's top 10 employers (and number of employees) are:
The Del Amo Fashion Center, at 2.5 million square feet (232,000 m²), is one of the five largest malls in the United States by gross leasable area.
 The current mall was created when Del Amo Center, built in 1958, merged with Del Amo Fashion Square, built in 1972.
 Once located on opposite sides of Carson Street, a gigantic expansion of the mall spanning Carson Street joined the two centers by 1982, making it the largest mall in the world at the time.
 In 2005, the east end of the original mall north of Carson Street was demolished to make way for a new open-air shopping center, opened in mid-September, 2006.
This was followed in 2015 by the opening of an expanded northern Fashion Wing, with Nordstrom as the mall anchor and supplemented by luxury retailers such as Kate Spade, Hugo Boss, Uniqlo, Michael Kors, and Ben Bridge.
The Old Towne Mall was an entertainment-themed mall operating in the 1970s.

As a major oil-producing region, Torrance was once dotted with thousands of oil wells and oil derricks.
 Though the oil wells are not as common as they once were, the Torrance Refinery Oil refinery owned by PBF Energy in the north end of the city is responsible for much of Southern California's gasoline supply.
Torrance was also an important hub and shop site of the Pacific Electric Railway.

Torrance has a general aviation airport, originally named simply "Torrance Airport" and since renamed Zamperini Field after local track star, World War II hero and Torrance High graduate Louis Zamperini.
The airport handles approximately 175,000 annual take-offs and landings (473 per day), down from the 1974 record of 428,000 operations.
Airport noise abatement is a major local issue.
In 2007 the Western Museum of Flight moved to Zamperini Field.

Torrance is also home to the main bakery facility for King's Hawaiian, the dominant brand of Hawaiian bread in North America.
Younger Optics, Torrance's 10th-largest employer, created the first seamless or "invisible" bifocal.

The headquarters of Mitsuwa Marketplace and Nijiya Market are located in Torrance.
