Based on the knowledge-based theory, this study uses multiple regression methods to study the performance mechanism of R&D investment by using data from 190 GEM listed companies in China from 2011 to 2015. The main conclusions obtained include: first, R&D investment promotes long-term performance better than short-term performance; second, the intellectual property protection positively regulates the relationship between R&D investment and long-term and short-term performance of enterprises and in areas with strong intellectual property protection, and R&D investment can improve long-term and short-term performance of enterprises.
