As the cornerstone of urban development, urban economic competitiveness measures the strength of urban economic development and also reflects the vitality and power of regional economic development. The latest report released by the Chinese Academy of Social Sciences shows that the comprehensive economic competitiveness of Chinese cities is still in a state of "strong in the south and weak in the north". The level of economic competitiveness of southern cities is significantly higher than that of northern cities, and the degree of difference between southern cities is lower than that of northern cities. Specifically, among the top ten cities, there is only one city from the north: Beijing, among the top20 cities, there are only three: Beijing, Qingdao and Xi’an, and among the top 50, there are only nine from the north including Beijing, Qingdao, Zhengzhou, Xi 'an, Jinan, Yantai, Taiyuan, Tianjin and Dongying. To be specific, among 130 cities in the north, 78 cities declined in economic competitiveness ranking, accounting for 60%, and 52 cities have increased their economic competitiveness ranking, accounting for 40%. The decline rate is significantly higher than the increase rate. Northeastern cities generally declined, with an average drop of 9.75. It should be noted that only Shandong has a strong economic competitiveness in northern provinces, and the recession of economic competitiveness of northern cities has spread from Liaoning, Jilin, Heilongjiang and Inner Mongolia to Hebei and Shandong, and is now approaching Henan.
