Featured Graphic. The Declining Impacts of Danwei on Commuting? Visualization of Journeys to Work from Danwei and Adjacent Areas in Xi'an, China
利用2011年西安家庭出行调查数据，绘制了109个单位大院及其周边区域的通勤流地图，发现多数单位大院的主要工作地已不在院内，且周边非单位居民与单位居民共享部分工作地。
Jobs–housing balance describes the relationship of housing stocks and jobs within different subdivisions of a city or within a reasonable commuting distance/time from points of interest (Cervero, 1989; Giuliano, 1991). Many advocate for jobs–housing balance to reduce commuting distance, car dependence, and associated congestion and air emissions. According to the planning doctrine in the Socialist era, the working-unit, or Danwei, is a good way to realize jobs–housing balance. Recent case studies indicate that Danwei’s impacts on the jobs–housing relationship and commuting may still persist (Wang and Chai, 2009; Zhao et al, 2011). At the city or regional levels, however, there have rarely been geocoding and visualizations of Danwei and associated commuting flows. Using the commuting data from the 2011 Xi’an Household Travel Survey (N = 59 967), we made two maps, which show all 109 Danwei compounds in the city and commuting flows associated with these compounds and their adjacent areas (figures 1 and 2). The maps shed new light on Danwei and commuting in post-Socialism cities. First and above all, we see that for the most Danwei compounds, the top destinations (workplaces) are no longer within or even around the same compounds (figure 1). Second, many workers residing in the non-Danwei areas surrounding Danwei commute to the suburbs (figure 2). Interestingly, these workers share several common workplaces as their counterparts living in adjacent Danwei compounds.
