Based on the perspective of policy synergy, this paper uses the panel data of 1890 county-level cities in China from 2004 to 2017 to investigates the synergistic emission reduction effect of the smart city and low-carbon city development model from aspects of “quality” and “quantity” by using Recentered Influence Function decomposition and Difference in Difference in Difference model, and makes an extended analysis of their heterogeneity from the aspects of region, scale and emission reduction pressure. The results show that the superposition of low-carbon city and smart city development model accelerates the green and low-carbon development of cities. In the view of “quality” point, the carbon emission reduction effect of smart city construction is greater on the basis of low-carbon city development model. From the “quantity” point of view, the construction of smart cities has made low-carbon cities more low-carbon. However, the synergistic emission reduction potential by the superposition of the two types of urban development models is released only in the eastern and central regions, large and super-large cities and cities with greater emission reduction pressure. Accordingly, we propose that we should innovate urban development model, and stimulate the potential of coordinated emission reduction; classify promotion of urban wisdom development on the basis of low carbon; strengthen policy coordination in the process of superposition of urban development models.
