Creating a high-level opening-up pattern and accelerating the implementation of the innova-tion-driven strategy are important engines for high-quality economic development with the new develop-ment concept.Based on the sample data of 258 cities in China,this paper uses Tobit model and semi-parametric estimation method to empirically analyze the internal relationship between trade open-ness,innovation drive and high-quality economic development.It is found that trade openness,innova-tion drive and their interaction show a significant positive impact on high-quality economic develop-ment.Heterogeneity analysis shows that the promoting part of trade openness and innovation drive in non-clustering cities is bigger than that in clustering city,but their integration inhibits the high-quality economic development of non-clustering cities.The threshold effect test shows that the promoting part of trade opening in high-quality economic development influenced by the level of innovation drive has single threshold effect test,Therefore,it is proposed to speed up the construction of the highland open-ing up to the outside world,improve the system of introducing innovative talents,and strengthen the co-ordination and linkage between clustering cities and non-clustering cities in order to achieve high-qual-ity economic development.
