The elliptic equation strategic smart city brand aecity and digital construction product CIM engine 3.0 were launched in Shenzhen, officially sounding the horn of smart city digital construction.

The state attaches great importance to it and local governments actively promote it

Smart city is an advanced stage of human social development. Smart city construction can effectively promote urban sustainable development. Through the construction of smart city, the core competitiveness of the city can be comprehensively improved. In recent years, in order to promote the healthy and orderly development of China’s new smart city, the central and local governments have successively issued a series of policy initiatives and strategic deployment to optimize the development environment.

The development of smart city not only benefits from the high attention of the national level, but also depends on the promotion of the local level. In April this year, the national development and Reform Commission proposed to implement the “new smart city action”, which requires to improve the urban digital management platform and perception system, integrate multi domain information systems and data resources, deepen the “one network” of government services and the “one network unified management” of urban operation, so as to support the healthy and efficient operation of the city and the rapid and intelligent response to emergencies.

Elliptic equation actively responds to policy and market demand, and devotes itself to the construction of a new smart city for four years. With years of experience in the development and construction of urban data platform and full independent research and development, the elliptic equation team officially launched the strategic smart city brand aecity and the digital construction product CIM engine 3.0.
