How does Basic Research Promote the Innovation for Patented Invention: a Measuring of NPC and Technology Coupling

Abstract

When a new technology is invented, it may absorb new knowledge from basic research. But how to evaluate the affection of basic research on technological invention and innovation accurately is difficult. The paper constructs a model for measuring the relationship between basic research and patented invention by quantitative analysis. The research introduces the concept of technology coupling which can be used for measuring technological complexity in the process of patented invention. The paper develops an empirical research by USPTO patent datum to identify that basic research play a more important role for those patented inventions at high level of technology coupling. And the research indicates a positive correlation between patent value and utilization of basic research.
