Mumbai has traditionally owed its prosperity largely to its textile mills and its seaport until the 1980s. These are now mostly replaced by industries employing more skilled labour such as engineering, diamond polishing, healthcare, pharmaceutical marketing and information technology. Mumbai is today India's primary financial centre, housing both major Indian stock exchanges (the Bombay Stock Exchange and the National Stock Exchange, which are the 9th and 10th largest stock exchanges in the world by market capitalization), brokerages, asset management companies (including the majority of Indian mutual funds), the headquarters of most Indian state-owned and commercial banks, as well as the financial and monetary regulatory authorities of India (the Securities and Exchange Board of India and the Reserve Bank of India) and many other institutions. As Mumbai is the capital of Maharashtra, government employees make up a large percentage of the city's workforce. Mumbai also has a large semi-skilled labour population, who primarily earn their livelihood as hawkers, taxi drivers, mechanics and other such proletarian professions. The port of Mumbai and shipping industry too employs many residents directly and indirectly. Like most other metropolitan cities, Mumbai also has a large influx of people from rural areas looking for employment. The entertainment industry is Mumbai's other major employer. Most of India's television and satellite networks are located in Mumbai, as well as the major publishing houses. A large number of the Hindi and English television shows are produced in Mumbai. The Hindi movie industry, also known as Bollywood, is also located in Mumbai, along with the largest studios and production houses. To add to this, most major advertising companies operating in India also have their primary office in Mumbai. Industries

Another key contributor to Mumbai's economy is the transport sector. The city has been investing in and developing various transport related infrastructure projects. Mumbai Suburban Railway, popularly referred to as Locals forms the backbone of the city's transport system. It is operated by the Central Railway and Western Railway zones of the Indian Railways.

The Mumbai rail network is spread at an expanse of 319 route kilometres. 191 rakes (train-sets) of 9 car and 12 car composition are utilized to run a total of 2,226 train services in the city. The Mumbai Monorail and Mumbai Metro have been built and are being extended in phases to relieve overcrowding on the existing network. The Monorail opened in early February 2014. The first line of the Mumbai Metro opened in early June 2014. Mumbai is the headquarters of two zones of the Indian Railways: the Central Railway (CR) headquartered at Chhatrapati Shivaji Terminus (formerly Victoria Terminus), and the Western Railway (WR) headquartered at Churchgate.

BEST introduced air-conditioned buses in 1998. BEST buses are red in colour, based originally on the Routemaster buses of London. Maharashtra State Road Transport Corporation (MSRTC, also known as ST) buses provide intercity transport connecting Mumbai with other towns and cities of Maharashtra and nearby states. The Navi Mumbai Municipal Transport (NMMT) and Thane Municipal Transport (TMT) also operate their buses in Mumbai, connecting various nodes of Navi Mumbai and Thane to parts of Mumbai. Buses are generally favoured for commuting short to medium distances, while train fares are more economical for longer distance commutes.

Though 88% of the city's commuters travel by public transport, Mumbai still continues to struggle with traffic congestion.

The proposed Navi Mumbai International airport to be built in the Kopra-Panvel area has been sanctioned by the Indian Government and will help relieve the increasing traffic burden on the existing airport.
