Abstract: Sociologists believe that most of economic activities of enterprises are embedded in social networks, which can bring valuable scarce resources to enterprises for their own development, and then affect their behavior and decision-making. In recent years, the analyst industry has developed rapidly. Generally speaking, analysts will track multiple enterprises at the same time, so there will be common analysts among these enterprises. This connection relationship formed by common analysts tracking constitutes a complex social network, namely, analyst tracking network. At present, the technical structure is becoming more and more complex, and the “single fight” innovation strategy of enterprises makes it difficult for them to deal with it. Cooperative innovation has gradually become an important strategic choice for enterprises to enhance their innovation ability. As an information intermediary, analysts themselves have a lot of information about companies, and need to communicate frequently with enterprise management in their daily work. Can the network built by common analysts be a bridge for information transmission among enterprises, and then affect the cooperative innovation of enterprises?
Based on the social network theory and the data of A-share listed companies from 2007 to 2020, this paper empirically tests the impact of analyst tracking network on enterprises' cooperative innovation. The results of the research are as follows: (1) The analyst tracking network can promote enterprises' cooperative innovation, and the field research is an effective way for the analyst tracking network to transmit information; (2) The impact of the analyst tracking network on enterprises' cooperative innovation is more significant in enterprises with strong absorptive capacity, high-tech enterprises, and under the conditions of high economic policy uncertainty, high degree of marketization; (3)The analyst tracking network improves the enterprise value, and the cooperative innovation plays a partial intermediary role in it.
The main contributions of this paper are as follows: (1) It reveals the new role played by analysts as information transmission agents between enterprises. Domestic and foreign research has not paid much attention to the construction of information bridge between enterprises by analysts. This paper focuses on the influence mechanism of the social network formed by common analysts tracking on cooperative innovation, and further explores the new role playing of analyst profession. (2) It expands the research scope of the social network. In recent years, the research on the social network and the enterprise behavior has gradually increased, but a large number of studies mainly focus on the network built by directors and shareholders, while few studies take the analyst tracking network as the entry point. Compared with other networks, the analyst tracking network has its uniqueness. As an information intermediary, analysts themselves master a large amount of information and need to communicate frequently with the management of the enterprise. Therefore, the connection formed by common analysts can promote the information flow among enterprises and influence enterprises' behavior and decision-making. (3) It enriches the relevant research on the influencing factors of enterprise cooperative innovation. Most of the existing literature explores the influence of the social network on enterprise cooperative innovation from the perspective of the structural characteristics and the relationship characteristics of the overall social network, but ignores the role of the social network constructed by different subjects. This paper broadens the research on the influencing factors of enterprise cooperative innovation from the perspective of the analyst tracking network.
