上海自由贸易区, or the Shanghai Free Trade Zone, was established in 2013 as China's first free trade zone. It aims to promote trade and investment by reducing regulations and allowing for more flexible business operations. The zone serves as a testing ground for economic reforms and innovative policies. The 自由贸易区 covers several districts in Shanghai and includes various industries such as finance, shipping, and technology. By attracting foreign investment and facilitating international trade, it plays a crucial role in enhancing Shanghai's position as a global financial hub.
