ABSTRACT
Although there is an abundant regional literature analyzing traffic congestion, only a few studies have explored extending such analysis with spatial effects. This study uses a dynamic spatial Durbin model and city-level panel data for the period 2003–14 to investigate the spatial spillover effects of traffic congestion on urbanization in China. The results show that there is an inverted ‘U’-shaped relationship between urbanization and traffic density in local and neighbouring cities, and congestion effects have appeared. In the short and long run, the spatial effects of traffic congestion have become an important force restricting the effective promotion of urbanization in China.

2 Under the hypothesis of classical NEG theory, the total amount of labour in city j can be obtained by solving the firm-maximization condition of the manufacturing firm, i.e., . Therefore, there is a one-to-one correspondence between the number in the urban labour force and the number of product varieties.
3 Han and Ke (Citation2016) tested the effects of factor proximity and market potential on manufacturing output. They used different distance-decay parameters (δ = 1, 2, 3) to test the accessibility variables (including market potential) and found that the models were better fitted and the coefficients slightly more significant using δ = 1. Therefore, we set the distance attenuation parameter in the market potential to 1 in the present paper.
