In the late 1990s, Florida intensified its efforts to attract high-tech, high-wage industries such as silicon technologies and aviation/aerospace industries. Florida became the first state in the nation to close its Department of Commerce. All of the state's economic development and international trade strategies are now handled through a partnership of business and government, Enterprise Florida. This new approach calls for collaboration among leaders in government, business, and academia. Enterprise Florida and its regional and local partner organizations provide a statewide network of business assistance resources in the areas of capital acquisition, technology commercialization, manufacturing competitiveness, training, minority and rural business development, incentives, site selection, permitting, and trade development. Through buying blocks of discounting tickets, arranging for bargain airfares, setting up meeting with local business people, and providing a distinctive Florida booth, Enterprise Florida lowers the cost of attending trade shows for Florida exporters. Promoting Florida exports has been a major concern of recent economic policy. As of mid-2002, Governor Jeb Bush had personally led trade missions to Argentina, Brazil, Chile, Israel, Mexico and the UK. The International Trade and Business Development unit of Enterprise Florida is based in Miami with six field offices in the state and 14 international offices, including ones in Frankfurt, Germany; London, England; Taipei, Republic of China; Toronto, Canada; Seoul, South Korea; Mexico City, Mexico; Tokyo, Japan; and Sao Paolo, Brazil. Florida has 14 deep-water commercial seaports; 5 barge ports; 9 major shallow-water ports; 4 river ports; and 16 customs ports of entry. As of 2003, 20 Free Trade Zones (FTZs) had been designated, all located at or near seaports and international airports. Value added in the FTZs is not subject to US customs duties unless processed goods are imported for sale in the domestic market.
