Narrowing the regional development gap is of great significance to achieving high-quality development，ensuring the effects of regional coordinated development strategies，achieving common prosperity，and promoting comprehensive and deepening reforms. In the new era，my country has already seen a widening gap in the development of large cities，a decline in the fiscal sustainability of individual regions，a widening gap in the development of different sub-regions within the province，the growing gap between the North and the South，and the development gap between different main functional areas. New trends such as expansion. In response to these new trends，regional coordinated development should be based on innate advantages and realizing measures to local conditions；based on comparative advantages and achieving complementary advantages；based on overall advantages and achieving scaled economy. On this basis，it is proposed that the future of coordinated regional development should adhere to the construction of a more restrictive institutional foundation，a more cohesive sharing mechanism，and a more driving layout idea.
