Abstract：Inquiry into the spatial pattern of the transportation network can not only clarify its enhancement of regional economy, but be an useful exploration within the development framework of modern transportation system. This paper uses the local MoranI index and the Moran index heat map to analyze the spatial correlation and spatial aggregation of the transportation networks of three provinces and one city in the Yangtze River Delta region, and constructs a spatial Dubin model to further study the direct, indirect, and overall economic benefits of transportation network density on regional development. The results show that the distribution of traffic network density in the region shows a divergent pattern centering on Shanghai-Jiangsu and moving toward Zhejiang-Anhui. Transportation network density has a significant positive spillover effect on economic growth, and the impact of indirect effects is much greater than that of direct effects. In order to achieve overall coordinated regional development in the region, it is necessary to make full use of the positive spillover effect between provinces and cities, strengthen the construction of interregional transportation networks, and reduce internal economic differences.
