The street market is a spatial vehicle that can deliver the thesis goal. Supply justice as a development strategy can incubate and mobilize the collective networks carried by the street market to practice inclusive urbanization. The collective making and street market as two symbiotic urban networks are potent instruments in promoting supply justice.
