  Itinerant peddlers are informal practitioners who retail and serve by setting up booths on the streets or other public places, often without a business license and a fixed business place. The problem of itinerant peddlers takes a great proportion of the urban social space contradiction in China. But the existence of itinerant peddlers is reasonable and necessary. Whether the diversion area can attract peddlers to settle in is the key to whether the “diverting-and-blocking” governance measure could work, which depends on whether the diversion area can meet the economic needs of the peddlers. If not, they will tend to operate informally, invalidating the inclusive governance policy.

  Therefore, the quality of the site selection of the diversion area directly determines the effectiveness of the “diverting-and-blocking” governance measure.

Study Area

  Jianghan, named after the intersection of the Yangtze River and the Han River, is the most prosperous center in Wuhan. Jianghan District is a comprehensive land mixed by public land, residential land, commercial land and green space, where it has a high potential for peddlers’ gathering. Jianghan District is selected as the representative and for the generalizability, reducing the research difficulty in the meantime.

Analysis Process

  Based on the research results of the existing literature, this work, choosing Jianghan District as the research area, uses 102 community units, population density data, vector road network data, housing price data and POI big data. It analyzes the locations where they have a high potential for peddlers’ gathering by 6 indicators (population density, housing prices, type of land use, comfort degree of block scale, diversity and abundance of urban functions). Combining with the “local standardization” principle and the specific control measures, the work provides guidance for regulating itinerant peddlers in the urban management system.

  To eliminate the difference in magnitude between the grid values in the six raster maps, the normalization process is adopted, and then analyze by the analytic hierarchy process, obtaining the contribution of each of the six factors affects the spatial distribution of itinerant peddlers.

  Six-factor Analysis


  By six-factor analysis, we obtain the recommended areas of (potential) high-incidence gathering of itinerant peddlers in Jianghan District, which can be also regarded as the locations of the diversion area.


  Based on previous research, the team is committed to providing a scientific analysis framework that can provide guidance for the location analysis of itinerant peddlers in various regions. We hope that, at the expense of the least urban public space, it is possible to not only preserves itinerant peddlers’ means of livelihood but also resolve the contradiction between the three major groups of itinerant peddlers, residents and urban managers.
