Research On The Co-evolution Of Digital Industry Innovation Ecosyste

China ’s economy is accelerating the upgrade from a speed-scale model to a quality-efficiency model,and accelerating the construction of a new development pattern with the domestic large-scale cycle as the main body and the domestic and international double cycles promoting each other.The digital economy has become a key support for building a new development pattern,and plays an critical role in promoting the effective improvement of economic quality and the rational growth of economic quantity.Although the scale of digital industry development is gradually expanding and its proportion in national economic growth is increasing,China still faces problems such as low competitiveness of digital economy development at the international level and obstacles in the circulation of enterprise factors at the domestic level.At this time,China needs to establish an innovation ecosystem with interconnected factors,explore the key driving forces to promote the collaborative evolution of the digital industry innovation ecosystem,and transform a single disorderly digital industry innovation ecosystem into a complex and orderly direction.In order to solve the problem of the key driving force to promote the co-evolution process of the digital industry innovation ecosystem,this paper takes the digital industry innovation ecosystem as the research object,based on the theory of synergetics and self-organization,expounds the connotation and characteristics of the innovation ecosystem,and combines the theory of ecosystem co-evolution and dissipative structure to determine the conditions for the self-organization evolution of the digital industry innovation ecosystem.Secondly,the scope and boundary of the digital industry are clarified,and the digital industry innovation ecosystem based on the Haken model is constructed.It is divided into four subsystems : human resource subsystem,innovation capability subsystem,factor supply subsystem and environmental support subsystem.The above four components are used as the four variables of the Haken model;thirdly,the evolution equation of digital industry innovation ecosystem from2016 to 2020 is constructed by using entropy method and Haken model,and the key driving factors of the co-evolution of digital industry innovation ecosystem are identified.The results show that innovation capability is the sequential parameter of the coevolution of the innovation ecosystem of the digital industry,and the factor affecting the change of innovation capability is human resources.There is a positive synergy relationship between innovation ability and human resources,but a positive feedback mechanism has not been established within the system to promote the continuous development of innovation capability in the digital industry.Therefore,it is necessary to actively improve the innovation ability of China’s digital industry innovation ecosystem and the synergy ability of human resources to meet the development needs of the system,and improve the positive feedback mechanism of innovation ability as a sequential parameter on system evolution,and the establishment of positive feedback mechanism of human resources to the system internally,so as to promote the process of collaborative evolution of digital industry innovation ecosystem.Finally,according to the empirical research conclusions,the following countermeasures and suggestions are put forward for the collaborative evolution of the digital industry innovation ecosystem: first,increase the number of digital industry innovation subjects,second,improve the quality of digital industry innovation subjects,third,increase the intensity of scientific research investment,and fourth,strengthen the integration and application of innovative technologies.
