TIANJIN -- The Beijing-Tianjin-Hebei low-altitude economy industry alliance was established on Saturday in North China's Tianjin municipality, with 33 related projects being officially signed.

The projects include the construction of a low-temperature battery production line and supporting facilities, and the overall planning of a low-altitude public route in a science park, among others.

Guests from Beijing, Tianjin and Hebei province, attended the ceremony, and watched a drone show demonstrating low-altitude application scenarios and business models in the air.

Guo Kangwei, head of the Baodi district of Tianjin, said the low-altitude economy is a typical representative of new quality productive forces, a new engine of economic growth and a new track of industrial development.

Baodi is vigorously promoting the deep integration of scientific and technological innovation and industrial innovation, and accelerating the cultivation of low-altitude economy-related industrial clusters, Guo said.
