The capital's mayor Boris Johnson said 50 so-called business improvement districts (BIDs) have been set up over the past few years, contributing more than £25m to regenerate town centres and industrial sites.
More than 60,000 firms now operate in the BID districts, with the number of jobs almost doubling since 2012.
The mayor said: "BIDs have played a key part in the regeneration of town centres and industrial estates and they continue to boost growth and help drive London's economy."
