We analyzed the mechanism of urban food desert expansion based on data at the block level. According to the food demand curve, the elasticity was high and the nutritional value diet decreased as the store prices increased. The store prices within 500m from the redevelopment would tend to increase because luxury supermarkets would dominate, while over 500m they would often tend to decrease because new non-luxury supermarkets would compete for opening. There are only two types of blocks with high risk of food desert: a block surrounded by multiple redevelopments or a block whose store price has gone up considerably.
