Abstract: The construction of innovative cities is a key component of new urban development, an essential task in promoting Chinese path to modernization, and a crucial focus in building an innovative nation. Cities, particularly innovative cities, serve as the source, concentration, and growth pole for the emergence of new quality productive forces. In turn, these new quality productive forces are the driving force and core support for the construction of innovative cities. The relationship between the two is characterized by an internal logic of "symbiosis" and "mutual construction". The mechanism through which new quality productive forces lead the construction of innovative cities is primarily reflected in the promotion of cities' digital, intelligent, and green transformation through technological advancements, driving efficiency, power, and quality changes in urban development through shifts in energy dynamics, and fostering networked, synergistic, and interconnected urban innovation through changes in model and strategy. The practical approaches in which new quality productive forces guide the construction of innovative cities include: (1) leading the consolidation of the foundation for scientific and technological innovation to promote the city's digital and green transformation; (2) facilitating the transformation between old and new driving forces to support the high-quality development of urban industries; (3) guiding the optimization of the innovation system and mechanisms to create a robust innovation ecosystem within the city; and (4) strengthening multi-dimensional collaborative innovation to foster the creation of an urban innovation community.
