海南封关倒计时，全球航司为何排队来这里修飞机？

Core Viewpoint - The Hainan Free Trade Port is set to officially launch its island-wide customs closure on December 18, which is expected to significantly boost the aircraft maintenance industry, attracting global airlines and increasing international flight routes [2][11]. Group 1: Aircraft Maintenance Industry Growth - The aircraft maintenance industry in Hainan has seen unprecedented growth, with the value of aircraft maintenance under customs supervision at Haikou Meilan Airport increasing by nearly 70% year-on-year in the first 11 months of this year [2]. - The one-stop aircraft maintenance base in Haikou has serviced over 2,400 aircraft this year, indicating a strong demand for maintenance services [5]. - The base has already filled its business capacity for the next three years, with an expected annual maintenance volume of around 700 aircraft post-customs closure [7]. Group 2: Advantages of Hainan Free Trade Port - Hainan's geographical advantage allows a 4-hour flight radius to cover 21 countries and regions, reaching 47% of the global population, while an 8-hour radius extends to 59 countries and 67% of the population [9]. - The policy advantages of the free trade port enable foreign airlines to save 10% to 15% on maintenance costs through tax exemptions and the ability to store maintenance materials in advance, reducing waiting times for parts by 2 to 3 months [9]. Group 3: Customs and Tax Policies - The customs closure will expand the range of "zero tariff" goods from 1,900 to approximately 6,600 tax items, covering about 74% of all goods, which is an increase of nearly 53 percentage points compared to before the closure [11]. - The management of imported "zero tariff" goods will shift to a negative list model, replacing the previous positive list approach [11]. Group 4: Air Rights Expansion - Hainan is the only province in China that has proactively opened up fifth and seventh freedom rights, with 14 fifth freedom routes already established [14]. - Following the customs closure, the seventh freedom rights will be fully opened, allowing foreign airlines to operate routes from Hainan to third countries independently [14]. - New international cargo routes have been added since September, enhancing the air economic corridor between Hainan and Europe and the Middle East [16].
