This study aims to analyze the formation mechanism, action mechanism, and evolution mechanism about the business model from the perspective of structure, and designs the enterprise business model architecture and forms a system, besides, explores approaches and strategies about enterprise carrying out business model innovation, and does beneficial bedding in order to use and improve the theoretical system in the process of the enterprise management practice. The significance of this study is to provide analytical methods and tools for the business model questions in the enterprise management practice. This paper firstly defined the connotation of enterprise business model and summarized the seven characteristics of the corporate business model. On the basis of outlining the enterprise business model design theory, the structural design of the corporate business model is mainly discussed. This paper designed the structure of the business model on modular perspective, proposed four constituent units and nine elements of enterprise business model structure system. Through the design of the enterprise business model structure and analysis of the elements that constitute structure, provide the basis for the transformation of innovative enterprise business model, or both enterprise business models, avoid the lack of elements of the enterprise business model structure and lead to business failure. Finally, the paper concludes with the five core strategies for the implementation of the enterprise business model design.展开更多

This aim is the result of a long discussion that has led to consider the public communication as a fundamental instrument supporting the dialogue between institutions and citizens and the result of an important sociological debate. Communication is nowadays considered as a structural element of Union＇s programs, and the transformation of the media system, the possibilities of communication offered by the social media, and the growth of participatory cultures have opened new ways to the development of European public communication that can contribute to increasing the European public sphere. This process involves an awareness from institutions and their representatives on the use of social media （e.g., Facebook, Twitter, etc.） to improve the relationship with the citizens and to create a sense of belonging to Europe.展开更多
