| Compared with wind energy,hydro energy,solar energy and other energy,emerging hydrogen energy is easier to obtain,has no regional restrictions,and is clean and pollution-free.Therefore,hydrogen energy has attracted much attention.Many countries began to develop hydrogen energy related projects,accelerate the breakthrough and development of hydrogen energy related projects,form a hydrogen energy industry chain,and improve enterprise efficiency.In order to obtain more enterprise benefits,some enterprises in China have carried out research and development on hydrogen energy related projects,and formed an industrial chain.MJNY is one of the most representative enterprises.The continuous research and development of hydrogen energy projects by enterprises and the improvement of the industrial chain are conducive to technological innovation,promoting China to become an innovative country,forming a stable industrial chain,responding to the policies to ensure the stability of the industrial chain,and further ensuring the stable development of the national economy.Based on the industrial chain theory,technological innovation theory,core competitiveness theory and input-output theory,this paper uses literature analysis,case analysis and quantitative analysis to study the case company MJNY.Firstly,the paper introduces the current situation of R&D investment in MJNY,and concludes that MJNY has some problems,such as insufficient R&D personnel investment intensity,insufficient R&D capital investment intensity,low R&D project specialization and low R&D investment autonomy.Secondly,by analyzing the impact of R&D investment in each stage of MJNY industry chain on enterprise benefits,it is concluded that with the extension of industry chain stage,the contribution of R&D investment in MJNY to enterprise long-term economic benefits is decreasing,while the contribution of R&D investment to enterprise short-term economic benefits,social benefits and ecological benefits is increasing,It shows that R&D investment can improve enterprise efficiency,but the lack of R&D talents,low efficiency of R&D input and output when increasing R&D investment,low degree of specialization of R&D projects will hinder R&D investment to improve enterprise efficiency.Finally,in view of the factors that hinder the R&D investment to improve the efficiency of enterprises,from the enterprise level,MJNY should pay attention to the introduction and training of R&D talents,strengthen cooperation with universities and R&D institutions,improve the efficiency of R&D input and output,and strengthen the specialization of R&D projects.At the same time,from the government level,under the supervision of the supervision mechanism,the government’s financial and policy support can effectively stimulate enterprises to carry out R&D activities,and then improve the efficiency of enterprises,and help enterprises layout the stable development of the industrial chain. |
