Engineering science and technology are important driving forces in the development of society, and engineering fronts are important guidelines for the future development of engineering science and technology. Understanding trends and aiming to be at the forefront of global engineering technology has become a strategic choice for countries around the world. Since 2017, the Chinese Academy of Engineering (CAE), in conjunction with Clarivate Analytics and the Higher Education Press, has been organizing a research project named “Global Engineering Fronts,” which aims to bring together talents in engineering and technology and push the fronts of global engineering research and development by reviewing papers and patent data. They also hope that the results of this project will provide a reference for people to respond to global challenges and achieve sustainable development.
