distinctive features, industrial structure optimization, service industry agglomeration and regional linkage.

1, distinctive features. The service industries of cities in the Yellow River Basin have different characteristics. For example, the rise of the central part of Zhengzhou has promoted the development of logistics and commerce, and the spring city culture in Jinan has attracted many tourists and cultural consumers, as well as the traditional Chinese medicine culture and traditional handicrafts in Henan and other places, which have become important supports for local service industries.

2. Optimization of industrial structure. The industrial structure of the service industry in the Yellow River Basin is constantly being optimized and adjusted, and it is gradually transforming from traditional trades such as commerce, catering and accommodation to knowledge-intensive, technology-intensive, innovative and high value-added services. For example, Henan Province is vigorously promoting the transformation and development of "internet plus" service industry, and promoting the improvement of service quality and efficiency.

3. service industry agglomeration. The distance between the cities in the Yellow River Basin is relatively close, and the service resources are gathered and enjoyed, forming a region with a relatively developed service industry. For example, Jinan National High-tech Industrial Development Zone, Henan New District Development, etc., all focus on the agglomeration development of service industry.

4. Regional linkage. The Yellow River basin is located between the two economic zones of North China and Central China, and also borders the northeast and northwest regions, forming a relatively complete economic region. The linkage between regions has greatly promoted the development of service industry.
