R&D Cost Stickiness and Enterprise Performance Based on Empirical Test Using WEISS Model

: As China's economy enters the new normal, scientific and technological innovation plays a more important role. This paper uses the WEISS model to measure the R&D cost viscosity of enterprises, and uses modeling tools to test the impact of enterprise R&D cost stickiness on performance. The research results show that the moderate R&D cost viscosity will have a positive effect on enterprise performance in the short term, and the positive action mechanism is more significant in non-state-owned enterprises; secondly, the higher the R&D cost viscosity, the more not conducive to the growth of enterprise long-term performance.
