# Data Element Sharing in Convergence Media Ecology Based on Evolutionary Game
## 3 Data Element Sharing Model Based on Evolutionary Game  
### Node Classification  
According to the characteristics of nodes in the convergence media ecology, there are two modes of relationship between nodes in the process of data element sharing based on the evolutionary game:  
1. Producer and consumer model  
In the producer and consumer model, producers and consumers are clearly distinguished, and each plays a different role. The producers are mainly news media organizations, enterprises, etc., the main function of which is the production of data elements, and the consumers are mainly common users, the main function of which is the use and consumption of data elements [57]. The advantages of this mode are as follows:  
1. Clear role: Producers focus on producing high-quality data elements, while consumers focus on acquiring, screening, sharing and interacting data elements. 2. Help to maintain data quality: Producers can better ensure data quality and reliability and reduce the risk of false information dissemination. 3. Research iteration: The node function in the system is clear, which is more convenient to study the system sharing efficiency so as to promote the system update iteration. The disadvantages of this model are as follows:  
1. Limiting innovation and engagement: Too much explicit role division may limit the motivation of common users to participate in data element production, reducing content innovation and diversity. 2. Information asymmetry: There may be information asymmetry between producers and consumers, resulting in some data elements that cannot be effectively spread and shared. Producer and consumer node pattern is shown in Figure 2.
2. Undifferentiated node pattern  
In this model, all participants are seen as differentiated nodes that can both produce and consume data elements. The advantages of this mode are as follows:  
1. Innovation and diversity: Encourage users to participate in the production of data elements and increase the innovation and diversity of content. 2. Fluent information flow: Undifferentiated node mode helps to break down the information barriers and realize the wider sharing and dissemination of data elements. The disadvantages of this model are as follows:  
1. Data quality is difficult to control: the lack of clear producer and consumer roles may make it difficult to guarantee data quality and reliability. 2. Resource allocation efficiency may be reduced: In the undifferentiated node model, participants may need to distract between production and consumption, potentially reducing the efficiency of resource allocation and utilization. 3. Difficult to target research: In the undifferentiated node mode, the functional characteristics of nodes are weakened, and it is difficult to reflect the targeted characteristics of research. Undifferentiated node pattern is shown in Figure 3.  
In order to facilitate the study of ecological data elements sharing based on the evolutionary game, analyze the game strategies of different roles in sharing of which the influence on the sharing of data elements, and, at the same time, guarantee the quality of data sharing, this paper adopts producers and consumers model to study the sharing process. In the ecological actual operational process, node can flexibly transform producer

At the same time, in order to ensure the enthusiasm of nodes to participate in sharing and the quality of sharing data elements, regulator nodes are introduced in the ecology. In conclusion, we divided nodes into three categories according to the functional positioning of nodes participating in data element sharing:  
1. Business organization node (\(B\)).
