The economy of Florianópolis is focused on the public, commerce and services sectors, with a main focus on tourism. The industry is not strong for environmental reasons, causing this sector to develop in the cities of the macro-region of Florianópolis. Despite this, the capital is highlighted when it comes to technology. Nearly 300 cutting-edge companies form the city's technology park, providing technology even for the international market. The revenue of this sector reaches R$ 500 million a year.  

tourism and events
The tourist sector in Florianópolis is a highlight and strongly moves the economy during the summer with around 500 tourists arriving here. They are the main source of income for hotels, restaurants, bars and other services da city, generating annual revenues of R$ 170 million. With the cold, the low season does not attract so many tourists to the beautiful beaches. That is why in the last decade this sector has undergone a transformation: throughout the year, Florianópolis holds the most diverse events, including congresses, lecture cycles, meetings of the most diverse professionals and sports competitions, such as Ironman Triathlon. These achievements are attracted by the structure that Florianópolis has, as it provides quality hotels and options for eating, drinking and going out at night. The city is also home to one of the largest events center in the country.  
fishing and mariculture
Artisanal fishing was once the livelihood of many native families in Florianópolis, but in the 1990s, with the advance of industrial fishing, it went into decline. Today there are few artisanal fishermen and even fewer who make fishing their only livelihood. What has grown in the last two decades on the island is the cultivation of seafood: shellfish and oysters are the main source of income for many families and businesses. Florianópolis is the largest producer of oysters in the country, with a share of 70% of the market and an annual turnover of R$ 7 million.  
In Florianópolis there is no agricultural production. The municipalities of Greater Florianópolis that form the Green Belt (Santo Amaro da Imperatriz, Águas Mornas, Antônio Carlos, São Pedro de Alcântara and Rancho Queimado) supply the capital with fresh produce, especially organic products.
