Tianjin Binhai High-tech Industrial Development Area, established in 1988 and approved as one of the first national-level high-tech zones by the State Council in 1991. It was designated as a national independent innovation demonstration zone in 2014. It consists of Huayuan Science and Technology Park, Marine Science and Technology Park, and Bolong Lake Science and Technology Park, covering a planned area of 100 square kilometers.

With the goal of "building an upgraded version of the national independent innovation demonstration zone" and "creating a first-class technology city in northern China," the area has formed a high-end industrial system centered around the information technology industry and supported by the new economy service sector, biopharmaceuticals, new energy, and high-end equipment manufacturing. Efforts are being made to develop the "China Information and Innovation Valley" and the unique "Cell Valley" in the Beijing-Tianjin-Hebei region. The construction of the Haihe Laboratory of Information Technology Application Innovation, Haihe Laboratory of Cell Ecosystem, Haihe Laboratory of Brain-Computer Interface and Human-Computer Integration is being accelerated. The area has attracted a group of strategic emerging industries represented by Sugon, Phytium, Kylinsoft, and 360, nurtured leading companies such as Yunzhongtong, Toutiao, and Tencent, and gathered a number of high-end research institutions, including the Fifth Academy of Aerospace, the Eleventh Academy of Aerospace, the 18th Institute of China Electronics Technology Group Corporation, the Advanced Research Institute of the Chinese Academy of Sciences, Zhejiang University Binhai Research Institute, and the Institute of Advanced Technology. It has become a region with abundant innovation resources, the largest number of independent intellectual property rights, and the greatest potential for economic growth in Tianjin. Efforts are underway to build an upgraded version of the national independent innovation demonstration zone and create a first-class technology city in northern China.
