# Data Element Sharing in Convergence Media Ecology Based on Evolutionary Game
## 1 Introduction  
In recent years, with the development of science and technology, the media industry has achieved rapid development and has experienced three development stages, from traditional media to new media and then to convergence media [1; 2]. Traditional media mainly comprises radio, television and newspapers, while new media is predominantly represented by mobile and Internet-based platforms. Convergence media, on the other hand, emphasizes the holistic evolution of media formats. Convergence media is a new media form that makes full use of media carriers and integrates different media such as radio, television, newspaper, mobile phone and Internet with both common ground and complementarity in terms of manpower, content, communication and governance [3]. As new media continues to develop, it brings about significant transformations in media patterns and modes of communication. The reorganization of various media forms and resources to form a joint force has become the main form of expression of media, which is also the main feature of the stage of convergence media [4]. In the convergence media ecology, different media organizations can establish connections by setting up unified standard application program interface, and at the same time, they can set up unified standard data formats and media resource libraries to realize the circulation of data elements so as to adapt to the impact of technological iteration. At present, the media industry is in a critical stage of the development of convergence media. The recombination of different media forms and resources and the application of artificial intelligence, big data, blockchainand other technologies have promoted the intelligent matching of information and user needs and improved the operation and maintenance efficiency of convergence media [5; 6; 7]. However, the development of convergence media still faces a series of problems and challenges, including information traceability, technology and media integration, data security and user privacy, and data circulation efficiency [8]. Data elements refer to data resources that participate in social production and management activities, bring economic benefits to users or owners, and are recorded electronically [9]. As a new factor of production, data have profoundly changed our mode of production, lifestyle and social governance. With the continuous innovation of data collection, governance, application, safety and other technologies and the rapid development of the industry, the current data element market construction has achieved remarkable results, the market environment has constantly improved, and the quality of data elements has been greatly improved [10]. With the advent of the era of big data, media have paid unprecedented attention to the integration and accumulation of big data resources [11]. Building a new platform of \"media data\" and seizing a new highland of \"data media\" has become the direction of many media organizations [12]. The goal of the research on the data element market is the efficient, orderly and free circulation of data elements among various market entities, which can be explained by the circulation mode of the data element, the circulation technology of the data element and the circulation system of data element [13; 14]. According to the different circulation of data and interests between subjects, its circulation mode can be divided into three types: opening, sharing and trading [15].
