Some changes have occurred during the urban development of Tianjin since 2018，such as the decline of economic growth rate，the continuous upgrading of the three-industry structure，the further deepening of the supply-side structural reform，and the steady advancement of eco-city construction. In order to achieve the basic positioning in national central city construction，Tianjin promoted the Beijing-Tianjin-Hebei coordinated development strategy，the construction of “one base and three zones”，and the strategy driven by openness and innovation，which have produced some results. However，Tianjin is still confronted with three major problems during the process of national central city construction. First，its economic growth is declining，and it is under a great pressure for transformation and upgrading. Secondly，further improvement is required in the platform construction intended to undertake non-capital functions from Beijing. Thirdly，the development of intelligent technology industry is still hindered by shortcomings of core technologies and relatively weak basic industries. Only by focusing on solving these problems，promoting the development of intelligent technology industry，improving the platform construction to undertake non-capital functions，and sharing accurate innovative resources with Zhongguancun，can Tianjin be truly built into a national central city with guiding，driving and distributing functions.
