In fact, Hainan has always been an economic special zone, the largest economic special zone in our country, but based on Hainan's economic performance, it doesn't quite deserve this title, so not many people pay attention to it. From a historical perspective, we can't blame Hainan; after all, Hainan's unique location, being an island primarily covered by mountains, coupled with the lack of road connections to the inland, makes it difficult for Hainan to develop a manufacturing industry. The economic special zones that have taken off over the past few decades have largely relied on manufacturing as their foundation. However, Hainan has its own characteristics, tourism. From a longer-term perspective, Hainan may not necessarily lose to economic special zones that are strong in industry, manufacturing, and technology. The recent closure operation refers to the establishment of a special area throughout Hainan Island that is monitored by customs, where the first line is open and the second line is controlled, allowing freedom within the island. After the island-wide closure operation, imported 'zero-tariff' goods will be managed under a negative list, replacing the previous positive list of 'zero-tariff' goods with a directory of taxable imported goods. Additionally, goods processed by enterprises in encouraged industries in the Hainan Free Trade Port that achieve or exceed 30% added value will be exempt from import tariffs when entering the inland through the 'second line'. It can be anticipated that Hainan will see significant development in the fields of trade and finance.
