The statistical table presents the Concentration Ratios (CR) in terms of business receipts, which are useful for analysing the extent of business concentration in selected industry groups of Hong Kong. It should be noted that analysis of CR should focus on temporal comparison rather than cross-industry comparison, because the size of individual industries may differ widely, and smaller-sized industries generally tend to have higher values of CR. For concepts, methods, definitions of terms and notes relating to the CR statistics, please refer to the feature article " Statistics on Sectoral Concentration".
The above-mentioned feature article is normally published every two years. It presents the CR statistics for more industry groups and broadly highlights some key observations.
