Cultural soft power refers to the overall ability of a country to carry out cultural inheritance，cultural creation，cultural production，cultural trade，and cultural communication guided by core values，etc. It unfolds in multiple dimensions of historical inheritance，realistic development，and guidance of the future. The most fundamental driving force of the world’s century-long change is the scientific and technological industrial revolution and the acceleration of the rise and fall of great power. In this context，the success of a country’s cultural soft power strategy is closely related to its ability to cope with the world’s great changes. Urban agglomerations are not only the central embodiment of national technological and economic strength，but also the main creators and promoters of cultural soft power. They have become powerful engines of cultural soft power in the sense of stimulating innovative vitality，radiating innovative culture，and promoting creativity and creation. On the new journey of China’s comprehensive construction of a modern socialist state，urban agglomerations must become bases for inheriting and developing Chinese cultural heritage，highlands for gathering innovative resources and renewing innovative impetus，hubs for allocating domestic and foreign cultural resources，and engines for promoting Chinese culture to the world.
