A wide range of statistical indicators can be compiled from the results of annual economic surveys conducted by the Census and Statistics Department for analysing the business situation and performance of various economic sectors in Hong Kong. Among others, statistics on sectoral concentration can throw light on the extent of business concentration within individual sectors. A feature article analysing the extent of business concentration in selected economic sectors of Hong Kong, making reference to the Concentration Ratios and Herfindahl-Hirschman Indices compiled in terms of business receipts in 2011 and 2012, was published in the August 2014 issue of the Hong Kong Monthly Digest of Statistics. This article is an updated version of that article, presenting figures for 2013 and 2014.
