The establishment of the pilot Free Trade Zone(FTZ)reflects China's firm determination to fully open up,play a role in promoting trade facilitation,investment liberalization,innovation and diversification,and serve as an important platform for strengthening international cooperation and regional integration and development.Based on the panel data of 10 provinces in China from 2009 to 2022 and Liaoning Province as the research object,this paper uses the DID model to evaluate the impact of the establishment of Liaoning Free Trade Zone on the upgrading of its industrial structure and test its impact mechanism.The results show that the establishment of free trade zone in Liaoning Province plays a significant positive role in promoting the upgrading of its industrial structure,and the regional industrialization effect and technological innovation level play an intermediary role in the upgrading of industrial structure.Through the parallel trend test,the change of establishment time,the substitution variable and so on,the conclusion has strong robustness.Actively promoting the improvement of the innovation level of the free trade area and further expanding the regional spillover effect of the construction of the free trade area are the important development directions of the future free trade area.
