   This unique city has the San Francisco Center for Economic Development (SFCED) to attract and retain business specifically in San Francisco. It supports and encourages small local businesses. Their goal is to "strengthen business ties within the local community as well as spur growth and development throughout the Bay Area Regional Economy." Why San Francisco you may ask. Well, according to SFCED San Francisco's worker productivity doubles the national average. It also produces more patents than any other region in the U.S. and attracts 36% of the nation's total venture capital investments.
