Empirical analysis based on the extended trade gravity model

Based on the extended Trade Gravity Model, this paper uses the panel data of China and 43 trading partners in 2000-2015 to empirically examine the impact of importing countries’ TBT on China’s high-tech products export. The results show that whether the implementation of TBT or IPR of importing countries will inhibit China’s high-tech products export in different degrees. And if importing countries combine TBT with IPR to form more subtle TBT, it will significantly inhibit the export. China’s high-tech products export shows differences by industry, and the export of high-tech products in different segments of the industry is different from the TBT sensitivity of importing countries, in which the inhibition effect of pharmaceutical industry is the largest. Finally, due to the existence of technology imitation and product homogenization phenomenon, China’ s high-tech export will suffer more severe TBT in the middle and high-income countries, and the inhibition effect on export is greater. China should take IPR protection as a supplement to importing countries’ TBT.
