Research on development level and spatiotemporal evolution of new quality productivity in megacities

The development level of urban new quality productivity is of great significance for improving regional new quality productivity and leading high-quality economic development. However, the monitoring indicator system for the development level of new quality productivity in mega cities has not yet been systematically defined. On the basis of reviewing relevant policy documents and research literature, this article combined the characteristics of mega cities to determine the connotation of the monitoring and monitoring indicator system for the development level of new productive forces. It further constructed a monitoring system for the development level of new productive forces in mega cities. Then total index and sub-indexes of the monitoring system for the development level of new quality productivity in mega cities were measured based on the monitoring system. Relevant suggestions are proposed based on the calculation results, in order to provide reference for the government and relevant departments.
