The yellow economic circle, also known as the yellow economy, is a system of classifying businesses in Hong Kong based on their support or opposition to the 2019–2020 protests in the city. Proponents of the yellow economic circle frequent "yellow shops" and boycott "blue shops", the former supporting the protesters and the latter supporting the Hong Kong Police Force. Businesses affiliated with ("red shops") or owned by ("black shops") the Chinese Communist Party are also targets of boycotts and vandalism by protesters, which has led to the use of the alternate name anti-communist economic circle. Politically neutral businesses are labelled "green shops". Yellow shops that have supported pro-democracy protesters since the 2014 Umbrella Movement are sometimes referred to as "golden shops".
