Abstract: This paper uses the cluster analysis method to measure the level, type and pattern of the 1007 cities in the world from the perspective of urban economic competitiveness and urban function. Based on this, it studies 292 cities in China. The study found that:China's urban development level is slightly higher than the average level of urban development in the world. China's first tier cities and Hong Kong's economic competitiveness are in the leading position in the country, and the southeast region occupies half of the top ten cities; China's urban competitiveness levels have significant regional differences, showing that the eastern region is stronger than the western region. The southern region is better than the north and the coastal area is better than the inland overall structure. The hierarchical clustering analysis shows that China's top cities have a place in the forests of the world's cities. China's urban hierarchical structure is significant, and differences within and among levels are evident and growing. The results of type cluster analysis indicate that the cities in China currently lack the world's top center cities, but China's first tier cities, Hong Kong, and Taipei rank among the top cities in the world.
