Retailers’ store-level performance is crucial to their success. The China Chain Store & Franchise Association and the Li & Fung Research Centre have collaborated and established the Key Performance Index System（KPI）for retail chain operators. The KPI system measures the performance of 5 major retail formats，including convenience stores，supermarkets，hypermarkets，department stores and home electronics appliance chains on a regular basis. In this report，we share with you the KPIs of different format retailers in the second half of 2009. We hope this report can shed some light on the key development trends of China’s retail chain stores.
