In the context of the new development pattern,a domestic and international circular indicator system was constructed based on 30 provinces from 2010 to 2021.The entropy weight Topsis method was used to measure the domestic and international circular development level index.Based on this,a panel bidirectional fixed effects model was used to analyze the impact of the square terms of domestic circulation,international circulation,dual circulation,and dual circulation on economic growth,and heterogeneity and robustness tests were conducted.The final analysis concludes that the domestic and international circulation indices are showing an upward trend,and those with good development levels are mainly concentrated in economically developed regions,with the development level in the eastern region being higher than that in the central and western regions.The domestic cycle and dual cycle have a significant positive impact on economic growth,while the square term of the dual cycle shows a negative impact.Based on the conclusion,the following suggestions are proposed:strengthening domestic and international circulation,optimizing industrial structure,and increasing diversified imports and exports;implement regional differentiation policies,with a focus on developing underdeveloped areas;enhance North-South cooperation and achieve complementary resource advantages;reduce trade barriers and increase market openness;enhance their competitiveness and explore international markets.
