Tianjin Economic-Technological Development Area (TEDA) (天津经济技术开发区), one of the first national-level economic and technological development areas in the country, gained approval from the State Council in 1984. 

In the past 34 years, Tianjin Economic-Technological Development Area (TEDA) has introduced 3,231 foreign investment projects from 79 countries and regions, with a total investment of $106 billion.

TEDA achieved a GDP growth of 8.2 percent in 2018. The three major industries of automobile, equipment and biomedicine reached double-digit growth.

The development area is roughly made up of nine leading industries: the electronic communications industry represented by Motorola, Samsung, and Panasonic; the automobile industry led by FAW Toyota and Great Wall Motor; the biological medicine industry with GlaxoSmithKline (GSK), Novo Nordiskh, and Zhongxin Pharmaceutical as representatives; the food and beverage industry represented by Bunge, Ting Hsin International Group, Nestle, and Coca-Cola; the new energy, new materials, and environmental protection industry led by Vestas, Kyocera China, and Tianjin Motimo Membrane Technology; the equipment manufacturing industry with Otis, SEW, and John Deere as representatives; the petro-chemical industry represented by CNPC Bohai Drilling Engineering Company, GWDC, and Cabot Corporation; the aviation industry represented by the industrialization base for new-generation launch vehicle; and the modern service industries, including finance, logistics, and outsourcing industries. TEDA has become the largest production base for mobile phones, base stations, electronic components, flat televisions, enzyme preparation, solar panels, and instant food.

TEDA topped other national-level development areas in terms of investment environments for 12 years in a row evaluated by the Ministry of Commerce. UNIDO also rated TEDA as one of the six most dynamic cities and regions of China. World famous magazines "Fortune" and "Forbes" selected TEDA as "China's most admirable industrial park".
