In the 2018-2019，the overall service industry of the Yangtze River Economic Belt has developed well，and the proportion of each service has been continuously improved. The inter-regional development gap still exists，with advantages in the upper，middle and lower reaches. The cooperation and exchange of modern service industry in the Yangtze River Delta region have been deepening. The service industry in the middle reaches has been continuously upgraded. The upper reaches of the Yangtze River have grown rapidly. The inter-regional cooperation in the modern service industry in the Yangtze River Economic Belt has deepened and become a model for coordinated regional development in the country. In terms of industries，key industries such as finance，wholesale and retail，transportation，real estate，and tourism have also performed well. However，it still faces some bottlenecks. For example，the growth rate of development and the growth rate of investment are slowing down. The sustained momentum needs to be strengthened. Environmental pollution still exists. The pressure of green development is still large. The regional development gap is still large，and the coordination of the whole basin is not strong. Therefore，in the future，we should further improve planning and related laws，explore the road of coordinated development of environmental protection and regional industries，improve the transportation supporting system，optimize the development environment of modern service industry，deepen system reform，expand market opening，and promote the development of modern service industry.
