Xi'an Yanliang State Aviation High-tech Industry Base in Shaanxi Province is located some 50 kilometers northeast of downtown Xi'an, where large-scale aircraft manufacturing firms, an aviation research institute, aircraft test institute, aircraft test pilot college and aviation technical schools are concentrated. 

The base got the official go-ahead from the National Development and Reform Commission on August 11 in 2004 and the construction was officially started on March 24 in 2005. The whole base will cover a total area of 244.4 square kilometers and will consist of two parts: the core zone and the expansion zone. 

The core zone is planned to occupy an area of 40 square kilometers, of which 11.28 square kilometers have been completed, and with the support of the enterprises and research institutes now extant in Yanliang, the core zone will serve as the center of aircraft design, manufacturing, and test flight appraisal.

The expansion zone refers to the province's central area, mainly engaged in the research, development, and production of aircraft on-board equipment and installation.

The base will rely on and make full use of the rich aviation resources in Shaanxi Province, to strive for its 2010 targets that include: reaching a yearly aviation output volume of 20 billion yuan (US$2.42 billion); greatly upgrading the level of aviation engineering; cultivating 10 key aviation enterprise groups and 1,000 related corporations to form an industrial chain; establish a technological and innovation system with industrial characteristics; build up a batch of key projects with individual intellectual property rights; and form complete and functional services.
