Research on the Threshold Effect of China’s Pharmaceutical Export Trade on Internal and External R&D Investment

Abstract

Objective To study the threshold effect of export trade on internal and external R&D investment in China’s pharmaceutical industry, and to provide reference for some pharmaceutical enterprises to improve the investment. Methods The panel data of pharmaceutical industry in 25 provinces and cities in China from 2009 to 2019 were selected to conduct empirical analysis by establishing a threshold regression model, and a better export trade interval was obtained. Results and Conclusion There is a threshold value for the effect of new product export on both internal and external R&D expenditures, and the threshold values are 845.278 8 million yuan and 318.419 8 million yuan, respectively. There is a single threshold effect of export trade on both internal and external R&D investment in China’s pharmaceutical industry, and the effect of export trade on internal and external R&D investment changes from negative to positive as the export trade develops from low to high.
