Abstract:Under the new economic situation, the integration and innovation of science and technology and finance on account of the implementation in the supply side of the structural reform and innovation-driven development strategy which China has vigorously promoted for are put forward a deeper level of urgent requirements. And these deep integration will quickly promote the efficient allocation of social resources and economic fusion effect. In this paper, we explored the coupling mechanism between scientific and technological innovation groups and financial innovation groups from the perspective of group dynamics. Then, we use the order function function and the coupling coordination function to quantitatively analyze the coupling coordination degree of the scientific and technological innovation groups and the financial innovation group. The results show that the coupling status of scientific and technological innovation groups and financial innovation groups in Guangdong Province has been improved in recent years, and the coupling coordination degree has been increasing. Finally, this paper puts forward the countermeasures of information sharing and cross-learning mechanism, government coordination mechanism and macro-environmental protection mechanism and so on. These can effectively promote the effective coordination of scientific and technological innovation and financial innovation,help to further promote China to establish a sound finance of science and technology system and implement the supply side of the structural reform and other national strategies.
