Outline
To empirically analyze the relationship between the level of economic development of China's pharmaceutical manufacturing industry and R&D capital investment in order to provide reference for improving the level of economic development and R&D investment of China's pharmaceutical manufacturing industry.
The relevant data from 1995 to 2016 were selected and the VEC model was constructed and the Granger causality test was conducted based on the co-integration theory to analyze the influence between the two factors.
There was a long-term stable equilibrium relationship between the total industrial output value/GDP and r&d investment intensity of China's pharmaceutical manufacturing industry, and the long-term elastic coefficient was 0.515 1. The results of Granger causality test show that when the lag order is 1, 5 and 6, only the total industrial output value/GDP of pharmaceutical manufacturing industry is the Granger cause of R&D investment intensity.
The economic development level of the pharmaceutical manufacturing industry in China has a significant positive impact on the R&D capital investment, and the positive impact has a lag. The increase of R&D capital investment in the pharmaceutical manufacturing industry in the short term can not significantly improve the economic development level.
