The Impact of Pilot Free Trade Zones on the Upgrading of Industrial Structure:A Validation Based on the SDID Method
On the basis of analyzing the basic idea and related characteristics of the SDID method,this paper constructs an industrial structure upgrading index,studies the impact of pilot free trade zones on in-dustrial structure upgrading from the perspective of regional heterogeneity,and uses the DID method for robustness testing to strengthen the reliability of research conclusions.Based on the research results,this paper proposed to take institutional innovation as the starting point,and to accelerate the cultivation of new competitive advantages in international industries through"promoting opening up through reform,and driving reform through opening up".to further optimize regional industrial divisions based on regional advantages and characteristics,and achieve differentiated development,highlight the importance of deepe-ning regional strategic integration and strengthen industrial resilience through internal and external linkage and strategic coordination.
