今日起全岛封关，去海南旅游购物有啥影响

Core Viewpoint - The launch of the all-island customs closure in Hainan Free Trade Port on December 18 marks a significant step in China's commitment to high-level opening-up and the construction of an open world economy [1]. Group 1: Definition and Features of All-Island Customs Closure - The all-island customs closure defines Hainan Island as a special customs supervision area, implementing a policy characterized by "one line" being open, "two lines" being controlled, and free movement within the island [2]. - The "one line" refers to the more liberal and convenient movement of goods between Hainan and foreign countries, allowing for the release of eligible "zero tariff" goods [2]. - The "two lines" control the taxes and certificates for goods moving between Hainan and the mainland, ensuring that the "one line" open goods are managed appropriately [2]. Group 2: Impact on Tourism and Trade - The customs closure does not require additional permits for travel to Hainan, maintaining the same regulations for personnel and goods as before [4]. - The "zero tariff" policy has expanded from over 1,900 tax items to more than 6,600, increasing the proportion to 74%, benefiting all enterprises and non-enterprise units on the island [6]. - The policy allows for the free circulation of "zero tariff" goods and their processed products among eligible entities, optimizing the processing and value-added tax exemption policies [6]. Group 3: Future Policy Enhancements - The policy benefits will continue to be released, with plans to expand the range of duty-free goods available to residents and tourists [9]. - Research is underway on tax policies for imported goods for island residents, allowing for tax-free purchases of certain imported products [10]. - Hainan has implemented the most favorable visa exemption policies in the country, allowing for visa-free entry for citizens from 86 countries [10]. Group 4: Development Goals - The all-island customs closure is a milestone in the construction of the free trade port, marking the beginning of a new phase of open development [14]. - The construction of Hainan Free Trade Port is planned in three phases, with the first phase aiming to establish a policy system focused on trade and investment freedom by 2025 [15]. - The second phase aims for a mature system and operational model by 2035, while the final phase targets the establishment of a high-level free trade port with significant international influence by the middle of this century [15].
