This is the closest shopping mall close to me in Bangkok, which is called Siam Discovery. I think the most important stocks and flows are people and finance, but I'll choose finance as the most important. The main popuse of shop owners to set a shop in this shopping mall is to make profit, or money, whether in the form of goods, or services. For example, a furniture shop shown in the bottom of this photo, shop owner use money to get these furnitures stand there in the mall, so the money flow from the pocket of owner to producer or distributer, then the sofa is being sold, the money flows from consumers to the owner. In this case the stock of money is sofa. In the future, the shop owner may gone into bankruptcy due to the development of online shopping, nobody want to come to a mall for a sofa.
