| The clean energy vehicle industry,as an important starting point for the clean transition of transportation energy,is of great significance to China’s energy security,environmental protection,and the transformation and upgrading of the manufacturing industry.In recent years,the clean energy vehicle industry has developed rapidly with the strong support of China’s policies,but there are still problems such as low market share,incomplete infrastructure,and lack of core technologies.Compared with traditional fuel vehicles,clean energy vehicles are still in the initial stage of industrial development.From the perspective of industrial ecosystem,the development of an industry is not a single-point breakthrough of a single enterprise population,but the result of mutually beneficial symbiosis and interaction between interrelated subjects.The endogenous formation of various entities within the industry through competition and cooperation is an important force to promote the development of the industry.Therefore,in order to achieve the replacement of traditional fuel vehicles,it is essential to establish a complete clean energy vehicle industry ecosystem.Based on ecological principles and industrial ecosystem theory,this paper takes the clean energy vehicle industry ecosystem as the research object,establishes a clean energy vehicle industry ecological model,and divides it into clean energy subsystem,vehicle subsystem,consumer subsystem,and external environment,analyze its operation mechanism and driving factors.At the same time,uses the ecological theory,divides the life cycle of the industrial ecosystem into the construction phase,self-organization phase,system equilibrium phase,decline or transformation phase,and the evolution behavior of enterprise communities in the industrial ecosystem is analyzed at each stage.Taking the hydrogen fuel cell vehicle industry as an example,the system dynamics is used to construct its industrial ecosystem model,and the impact of different policy variables on industrial development is pointed out.It is pointed out that the difference in subsidy objects will affect the subsidy effect.The purchase subsidy has a strong effect on increasing the market size,the innovation subsidies for auto companies can significantly improve the technological level of enterprises.In addition,guarantee policies can create a good investment environment and promote investment in infrastructure construction.Finally,according to the research conclusions,specific suggestions and measures are put forward from the perspective of policy making and business operation. |
