Methods: First, the difference-in-difference (DID) empirical strategy is used to analyze the impact of the implementation of the GDT on the improvement of the primary medical attendance rate, and the parallel trend test and the placebo test were used to test the robustness to illustrate the necessity of policy implementation. Secondly, combined with customer value theory, this paper uses logistic regression model to study the impact of customer value perception on grass-roots medical care. Result: The implementation of the GDT can indeed improve the rate of primary care (p=0.028), but the impact is relatively small (0.042). From the perspective of value perception hierarchy, emotional value perception (p < 0.05) is the key factor that affects the grass-roots medical treatment behavior at this stage. Contribution: This paper fills the gaps in existing research, including empirical research on the grassroots medical treatment behavior of the masses under GDT and the impact of value perception on grassroots medical behavior. Besides, the recommendations are made for primary care institutions based on the analysis results, which promote the advancement of primary care services in China.
