In 2016，with the favorable economic situation，the urban competitiveness of Changchun city has been significantly improved，and the development level and equilibrium level have been improved，and the urban development is full of vitality. The comprehensive economic competitiveness is in the middle and upper reaches of the country，higher than the mean of the national cities，but the ranking is backward，and the economic growth is insufficient. The competitiveness of sustainable cities has been greatly improved，and the competitiveness of the whole region has been particularly prominent，but the competitiveness of information cities has declined，and Changchun has yet to open up to the outside world. Therefore，it is necessary to strengthen urban economic construction，enhance the inclusiveness and fairness of the city，and build a city with sustainable development and comprehensive competitiveness.
