The upgrading of export product quality propels the manufacturing industry to transition from a cost advantage to a quality advantage, facilitating the transformation of the trade model from quantity growth to a balance of quality and efficiency, and accelerating China’s progress towards becoming a trade power. The internal mechanism of service industry openness on the quality of manufacturing export products from the perspectives of the business environment and technological innovation was explored. Empirical analysis shows that for every 1% increase in the level of service industry openness, the quality of manufacturing export products improves by 0.373%, primarily attributed to the improvement of the business environment and technological innovation spillovers. Furthermore, the level of factor marketization also influences this relationship, exhibiting nonlinear characteristics. The enhancing effect of service industry openness on export product quality can only be fully exerted when the marketization of labor, capital and technological factors surpasses a certain threshold.
