Caption: Beijing Economic and Technological Development Area
Beijing Economic and Technological Development Zone (BJETDZ) was approved by the State Council as a state-level Economic and Technological Development Zone (ETDZ) on 25 August 1994. The first phase was planned on a 15 km 2 area. Located in Yizhuang in Daxing District, BETDZ is just next to the Beijing -Tianjin Expressway near the south 4th Ring Road of Beijing. Tiananmen Square, the heart of the capital city, lies 16.5 km north of BJETDZ.
In January 1999, when Zhongguancun Science Park (ZSP) was renamed by the State Council, 7 km 2 of BJETDZ was named Yizhuang Science Park and made a part of the ZSP. Consequently, this 7 km 2 area of BJETDZ offers preferential policies found in both national economic development areas and national high-tech industrial parks.
