Background

The "Hong Kong Standard Industrial Classification Version 2.0" (HSIC V2.0) is a statistical classification framework for classifying economic units in Hong Kong into relevant industry classes based on the nature of their major economic activities. HSIC V2.0 has been used by the Census and Statistics Department (C&SD) in the compilation, analysis and dissemination of industry statistics since 2009.

HSIC V2.0 is devised and maintained by C&SD by modelling on the “International Standard Industrial Classification of All Economic Activities (ISIC) Revision 4” promulgated by the United Nations Statistics Division and adapting to the local economic situation.


Structure of HSIC V2.0

HSIC V2.0 follows a 5-level hierarchical system. The top level categories are called Industry Sections (represented by 1-digit alphabet code). Under each Industry Section, there are different second level categories called Industry Divisions (represented by 2-digit numeric code), under which more detailed third level Industry Groups (3-digit numeric code), fourth level Industry Classes (4-digit numeric code) and fifth level Industry Sub-classes (6-digit numeric code) are available for refined classification. The hierarchical structure of HSIC V2.0 is summarised below:
