The new name has been in place for several years, due to the much extended range of the territory including the Dalian Free Trade Zone (Chinese: 大连保税区; pinyin: Dàlián bǎoshuìqū) to the south and Dalian DD Port (Chinese: 双D港; pinyin: Shuāng D gǎng) to the east.
Now Kaifaqu is a quickly expanding city, with a territory of 338 square kilometers, and a population of 360,000 including 31 ethnic groups: Han, Man, Hui, Chaoxian (Korean), Mongolian and other nationalities.
On April 9, 2010, in order to fully demonstrate gathering advantage and development vitality and further accelerate the process of urbanization of Dalian, Dalian Municipal Committee and Municipal Government decided to combine Jinzhou District and Dalian Economic and Technical Development Zone (Export Processing Zone, Golden Pebble Beach National 5A-Level Tourism and Holiday Resort included) and found Jinzhou New District.
To the east of the Development Zone, on the way to Jinshitan, is the Dalian DD Port, taking its name from Digital and DNA of the Bio industry.
Most of the enterprises in DDA are factories owned by foreign companies, especially from Japan, South Korea, Germany and the USA.
