Abstract:As the quantitative research on the development level of local standardization has not received enough attention, this paper analyzed the contribution of local standardization to high-quality economic development and its influence mechanism from the regional level. We use standard drafting information to assess the level of local standardization. Based on China’s 30 provincial panel data from 2002 to 2019, we estimate the influence of local standardization on regional economic scale and industrial structure and consider the regional heterogeneity by using the least squares method (OLS), individual fixed effect and two-way fixed effect regression method. The results show that the local standardization development significantly promotes local economic growth and industrial upgrading, and the economic growth effect is particularly obvious in inland areas, while the coastal areas benefit more from the industrial upgrading effect. We also find that the technological progress is an important mediating way for local standardization to affect economic growth and industrial upgrading, but the mediating effect of marketization is not significant. These results suggest that the leading enterprises in the eastern region should be encouraged to carry out the formulation of advanced technology standards, and lead the technological track evolution through the standards. At the same time, we should carried out pilot standardization projects in industrial agglomeration parks in western region and establish cross-regional standardization development coordination mechanism.
