Abstract:With the continuous deepening of the nested influence of scientific research and economic society, scientific research has received unprecedented attention. At the same time, it faces bottlenecks in its own development. The scientific research itself, the scientific establishment, and the scientific policy are in a state of change. It is necessary to understand the new laws of scientific knowledge production, and re-understand the interactive relationship between science, technology, and engineering to expand the boundaries of scientific research. This article analyzes the reasons for re-understanding scientific research, expounds the new connotation of scientific research from aspects of object, function and method, and puts forward policy recommendations to adapt the scientific changes.
