The international trade improves the technology innovation performance through technology spillover but the effect may be hindered with the GVC lowlocked in the developing country like China. Under the circumstance the coordination between the international trade and domestic trade becomes a possible way to strengthen the spillover effect. Specifically this coordination enhances the effect of completion and imitation as well as the relationship between the enterprises, which is named as ‘competitive driving’, ‘information diffusion’ and ‘connection of the value chain’. The specialization of the trade sectors also positively moderates the coordination. In the empirical section, we construct three indexes to measure the coordination and investigate the relationship between the coordination and the technology innovation with the fixedeffect model and the panel quantile model. Several robust tests are also utilized including changing the proxy of the technology innovation and using the discrete independent variable. We find that the coordination between the international and domestic trade is positively associated with the technology innovation and the effect of the coordination is strengthened in the area of which domestic trade sector is highly specialized.
