The theories of special externality and new-new trade are combined to deduce the dynamic impact of urban sprawl on firms' export, and then, Heckman two-step model is employed to investigate the nonlinear effect of urban sprawl on dual margins of the firms' export. The research results show that the impact of urban sprawl on the intensive margin presents a significant U-shaped trend due to the fact that urban sprawl alleviates market congestion and decreases agglomeration economies. In the meantime, the impact of urban sprawl on extensive margin of firms' export presents a significant inverted U-shaped trend. After dividing the samples according to the aspects which include the degree of urban sprawl, the region the firms are located in, the features of the industry, and the ownership of firms, the results indicate that there exists significant difference among the impacts of urban sprawl on different firms. Moreover, the results of the research provide us with empirical evidence and policy insight into the link between the firms' export and urban sprawl.
