Abstract:Expand the research objects of the innovation system, and study the construction of the innovation system of the comprehensive national science center. Take the comprehensive national science center of the Greater Bay Area as an example, use analytical tools such as innovation value chain and innovation mechanism to construct a research framework of innovation system for comprehensive national science center, analyze the innovation value chain of Songshan Lake Science City , and find that Songshan Lake Science City has initially built an innovation system with a complete chain. Comprehensively analyze the coordination mechanism of the smooth innovation chain, the guarantee mechanism that brings together innovation elements, and the motivation mechanism that stimulates innovation vitality, refine the advanced experience of the comprehensive national science center at home and abroad, and find that the Songshan Lake Science City has problems such as weak basic research , insufficient opening coordination mechanisms, insufficient function of guarantee mechanism and insufficient motivation and comprehensiveness of motivation mechanism, propose that the Songshan Lake Science City should strengthen the construction of basic research system and build an open collaborative innovation mechanism, resource guarantee mechanism that gathers high-end innovation elements, and motivation mechanism that fully stimulates innovation vitality and other countermeasures and suggestions
