Some 32 per cent of Dubai's GDP is expected to come from the aviation sector by 2020, a new report has suggested.Released by Oxford Economics, the study added that the sector is also likely to account for 22 per cent of all of the emirate's employment."Aviation is one of the main engines driving Dubai's emergence as a global centre for trade, commerce and tourism," said Shaikh Ahmad Bin Saeed Al Maktoum, chairman and chief executive of Emirates airline."That is why we have created a business and regulatory environment that supports its growth by encouraging open competition between all airlines, efficient operations and customer satisfaction. There is no magic here. It's just good business."According to the report, which was commissioned by Emirates airline and Dubai Airports, the region is praised as being "consensus-based, highly-competitive and consumer-centric".Meanwhile, the Dubai Airport Show was officially opened earlier this week, with it hoping to attract investors to the emirate's aviation industry.
