为何中国能够做到海南封关？

Group 1 - The establishment of a free trade zone in Hainan is unique due to China's large-scale market of 1.4 billion people, which provides a significant advantage over smaller nations like Singapore and Dubai [3][4] - Hainan's area of 33,900 square kilometers is 47 times larger than Singapore, allowing for a more substantial economic impact without the fear of rampant smuggling or market chaos [3] - The "one line open, one line control" strategy in Hainan utilizes big data for smart regulation, effectively managing risks associated with free trade [3][4] Group 2 - China's stable policy environment, including a 15% corporate tax rate and a capped personal income tax for high-end talent, supports the development of substantial industries rather than mere transshipment trade [4] - The focus on four leading industries in Hainan encourages genuine research and manufacturing, contrasting with other countries that may have inconsistent policies [4] - Hainan's approach to free trade is seen as a test of China's confidence in high-level openness, demonstrating that with the right path and safeguards, greater openness can lead to stronger development momentum [4]
