Abstract Under the background of big data, achieving equalization and digitization of basic public services and narrowing the regional economic gap are the main problems facing regional coordinated development in the new era.

The study concluded that the economic growth of UA-YRD is conducive to the improvement of the quantity and quality of public services, especially for the public services of education and health care, while the competition among local governments is negatively correlated with the supply of public services. and put forward targeted suggestions from the perspective of co-construction and sharing of digital public services for people’s livelihood.
