Taking America 2050, Future Ruhr 2030, New York 2030 and some other long- and medium-term strategic plans as examples, the paper analyzes the evolution of long- and medium-term strategic planning from the aspects of plan-making methods, analyzing techniques, research contents development trends etc. at the state, regional, and city levels. Based on international experience, this paper puts forward the necessity for Beijing to launch a new long-term strategic planning study "Beijing 2049." The innovation, challenges and development direction of "Beijing 2049" is also expounded in the paper.展开更多
