Since the establishment of CAE, entrusted by the relevant ministries and commissions, the academy has offered consultancy to the State on major programs, planning, guidelines, and policies. With the incitation by various ministries of the central government as well as local governments, the academy has organized its members to make surveys on the forefront, and to put forward strategic opinions and proposals. These entrusted projects have played an important role in maximizing the participation of the members in the macro decision-making of the State. In the meantime, the members, based on their own experiences and perspectives accumulated in a long term and in combination with international trends of the development of engineering science and technology, have regularly and actively put forward their opinions and suggestions.
