Abstract: Drawing on national standards data from the National Public Service Platform for Standards Information, this study matches these data with information from the China Industrial Enterprise Database and the China Customs Database. It theoretically analyzes and empirically tests the relationship between standard institutional opening-up and firms position in the international division of labor. The findings show that standard institutional opening-up has an inverted U-shaped effect on firms position in the international division of labor, an effect that remains evident in the more practically relevant sample of listed firms and exhibits dynamic persistence. Import competition, the volume of imported products, and the range of imported products are important channels underlying the inverted U-shaped relationship, with import shocks arising primarily from the consumption of imported products in coastal regions. Standard institutional opening-up overturns the conventional firm-size paradox, exerting a stronger effect on small and medium-sized enterprises than on large firms. Moreover, the effects are particularly pronounced for newly established and revised standards. These findings underscore the importance of advancing standard institutional opening-up at a measured pace and identify a pathway through which firms can move toward higher-value-added activities. They also provide policy implications for calibrating the intensity of policy intervention and promoting quality upgrading and efficiency improvements in foreign trade.
