| In 2004,the advent of graphene attracted worldwide attention.With its excellent physical and chemical properties,graphene has become an important component in the field of new materials in strategic emerging industries.Graphene not only has a profound impact on electronic information,new energy,aerospace,seawater desalination and other fields,but also is more likely to cause a disruptive technological revolution after the "Silicon Age".Compared with other developed countries,although China is rich in graphite resources,it started late,and there are certain deficiencies in technological innovation and product transformation,industrial scale and commercial development,and macro environment improvement.Therefore,it is of great significance to analyze the status quo of graphene industry technological innovation and explore the development direction of graphene industry technological innovation.This paper firstly uses the data envelopment analysis method combined with the Malmquist index to measure the technological innovation efficiency of 14 listed companies in Shanghai and Shenzhen from 2016 to 2020,from four aspects: comprehensive technical efficiency,pure technical efficiency,scale efficiency and Malmquist index.Conduct analysis to understand the status quo of technological innovation efficiency of graphene industry;further,build an SD model of China’s graphene industry technological innovation system,analyze key factors affecting the development of industrial technological innovation from a systematic and dynamic perspective,and explore graphene industry technological innovation System optimization direction.The research results show that:（1）There is huge room for improvement in the technological innovation efficiency of my country’s graphene industry.Some enterprises in the industry have low technological innovation efficiency,and there is a problem of unbalanced technological innovation efficiency among enterprises,but the gap is gradually narrowing;（2）In terms of industrial policy,financial support policies and tax policies have a significant positive effect on the development of China’s graphene industry,and capital is still the core factor affecting technological innovation in the graphene industry;（3）In terms of macro environment,the financial environment and legal environment Improvement has a significant positive role in promoting the development of the graphene industry.In comparison,the financial environment has a more obvious role;（4）In terms of the main body of graphene industry innovation,the improvement of technology conversion capabilities and the degree of integration of production,education and research will promote the graphene industry.Development has a significant positive effect,in comparison,the degree of industry-university-research integration plays a more significant role. |
