Free Trade Zone and Total Factor Productivity in the Epidemic Era Synergy Relationship

At the beginning of 2020, the sudden pneumonia epidemic has had a huge impact on the entire global industrial chain and supply chain management. De-Sinicization of the global industrial chain will become a trend in the short term, and China's economic security is facing challenges. The "dual cycle" policy is a major strategic deployment formulated by the central government in accordance with the development of domestic and international situations. At the same time, the continuous expansion of China's free trade zone is also a strategic consideration for the CPC Central Committee and the State Council to comprehensively deepen reform and opening under the new situation. The pilot free trade zone is a new engine to promote full opening in the new era, and it is also the main base for promoting dual-cycle development. Therefore, the top priority is to become a pioneer in implementing central opening. Since the establishment of the Shanghai Free Trade Zone, China's first free trade zone in September 2013, the scale of China's free trade zone has been expanding.
