Abstract:bet365 games is always accompanied by the emergence and spread of economic fluctuations，Suppressing economic fluctuations has become an important way to curb bet365 games，The interest relationships formed by the global value chain (GVC) have attracted much attention for the role of GVC in reducing global economic fluctuations。Based on the optimal tariff model including economic fluctuation parameters，Explore the inhibitory effect of GVC embedding on bet365 games from the perspective of economic fluctuations and conduct empirical testing，It can be found that GVC embedding has an inhibitory effect on bet365 games，Suppressing economic fluctuations is an important mechanism embedded in GVC to suppress bet365 games，And the GVC embeddedness of GVC-dominated countries has an inhibitory effect on bet365 games by smoothing economic fluctuations，GVC following countries have no significant effect on restraining bet365 games through this mechanism，It may even exacerbate economic instability，Causing bet365 games。As a country’s GVC leadership capability improves，GVC embedding calms economic fluctuations，The effect of inhibiting bet365 games is gradually obvious。
