Economy

[edit | edit source]

Most of the city's active labor is absorbed by the commerce and services. In spite of that, the primary and secondary sectors, specially agribusiness, still play an important role in the local economy. The farming of livestock supplies local slaughterhouses, which in turn allows Imperatriz to export meat to other states in Brazil and abroad. In addition to food processing and agribusiness, construction and non-metallic mineral processing are important. The area's most important crops are soy, rice and cassava. Recently, sugar cane has become important as well. According to IBGE, Imperatriz has a total of 5,657 commercial and 730 industrial enterprises.

The city is served by Prefeito Renato Moreira Airport.
