he factor endowments of airlines industry include human resources, capital, equipment and facilities, air space resources, etc.
In human resources, due to the characteristics of technology-intensive in airlines industry, the organization requires a lot of professional and technical personnel. Meanwhile, the aviation industry also needs administrative, financial investment and sales staffs. The multi-cultural Singaporean workforce is highly educated, highly motivated and highly productive. It is also proficient in English – the language of international business. Singapore has a large base of engineering talent, with the number of engineers in universities and polytechnics expanding steadily each year, in addition to the sizeable pool of skilled technicians. In addition, Singapore government through the open immigration policy enhances Singapore’s talent pool. This gives companies the opportunity to source for the best personnel from anywhere in the world (http://www.edb.gov.sg/edb/sg/en_uk/index/why_singapore/knowledge.html). For these reasons, the Singapore airlines industries have good manpower.
In capital, airlines industry needs a large finance support, the aircrafts and airport cost millions of money. In Singapore, the world's major banks have opened branches or offices. Therefore, the Singapore airline industries do not have problem in capital. For example, Commerzbank Singapore branch has 30 years’ experience in financing aircraft to arrange and manage the entire deal, and a complete suite of financing products (https://www.commerzbank.com.sg/en/financing/aircraft/aircraft_financing.htm).
Although the Singapore's skies are limited, however the airline industry not far from reaching saturation point. According to Lee Kuan Yew (former Prime Minister of Singapore), due to the aid of advanced navigation technology, Singapore can shorten the distance of the aircraft flight and to increase flights density, therefore Singapore in terms of the open skies, still have a lot of space.
