摘要：Difficulties in accessing food exist in some Chinese cities, and it can be a challenge for residents to buy affordable, good-quality and nutritious fresh foods. This study proposes a residential building-based measure to evaluate food accessibility based on Geographic Information Systems. We used a total of eight types of food retailers and 28 food categories in our analysis and explored whether inequities in access to food existed among neighborhoods with different housing prices in the Dalian Development Zone using Kruskal-Wallis test methods. Our results show that 38% of residents living in 3724 residential buildings required between five and 10 min to access the nearest supermarket, while 10% required more than 20 min. The mean walking accessibility to stores with eggs (10 min) and with milk (10 min) was quicker than that to other types of food stores (14-16 min). In addition, high-wealth neighborhoods had better food accessibility than did low-wealth neighborhoods. However, in comparison to the other studied neighborhoods, those with medium-low-wealth had the highest level of food accessibility. Our results can be used by policymakers to better understand food access in residential areas and to help improve the food environment in Chinese cities.
