Based on the data of POI (point of interest) in Jiangsu Province and economic and social statistics data, we used the methods of the standard deviation ellipse, nuclear density, the nearest neighbor index, and multiple linear regression to discuss the spatial distribution pattern and agglomeration characteristics of urban commercial outlets at different levels and stages of development. We also revealed the influencing factors of regional differences in the wholesale and retails, residential and catering industries. It was found that the commercial outlets in Jiangsu Province had the distribution trend of moving northwest, indicating a relatively concentrated distribution pattern and the characteristics of agglomerating in the cities south of the Yangtze River and intensive layout in centers of the prefecture-level cities. The spatial distribution patterns of different types of outlets varied from one to another. In the wholesale and retail industries, the spatial clustering characteristics of outlets are the most significant, while the distribution of residential outlets is relatively balanced. The commercial structure of each city is characterized by the number of wholesale and retail outlets and restaurants, as the sales of wholesale and retail take the dominant place. The regional GDP, population size, per capita disposable income of residents, comprehensive accessibility of cities, and proportion of the tertiary industry are the main factors deciding the distribution of outlets. The influence of different factors on the distribution of commercial outlets diverse from each other. The proportion of the tertiary industry and regional GDP of Jiangsu Province have more powerful influence on the distribution of commercial outlets.
