Hong Kong International Airport (HKIA) generates enormous economic value for Hong Kong. In 2008, the total economic contribution made by Hong Kong's aviation industry and related businesses amounted to HK$78 billion in value added, representing 4.6% of Hong Kong's GDP. The airport also supports Hong Kong's four main economic pillars - financial services, trading and logistics, tourism, and producer and professional services - which together accounted for 58.5% of GDP in 2011. These businesses rely heavily upon the efficient flow of people and goods made possible by HKIA.
Currently, the airport directly provides over 65,000 jobs. This number almost triples when indirect and induced employment - such as jobs created by hotel, catering, retail goods suppliers, the tourism industry, and more - are taken into account. Together they represent over 5% of the total workforce in Hong Kong.
