ABSTRACT
Urban-rural balancing has close linkage to sustainable development as it attaches to all of us in a way of mutual supplementation. Its critical role has even been highlighted since the spread of COVID-19, which has menaced our lives and highly impacts our environment. This research scrutinizes the rationalization process of urban-rural population and infrastructure to establish the static foundation. It further proposes time-space swap theory to trade “space” for “time,” to protect us as dynamic solutions.
