Knowledge interaction analysis of cooperative digital green innovation of photovoltaic building materials enterprises based on reciprocity theory

In the process of collaborative digital green innovation of photovoltaic building materials enterprises, knowledge sharing between photovoltaic building materials enterprises and academic and research institutions is conducive to the achievement of win-win goals of enterprises and academic and research institutions. However, due to the non-contractual relationship between cooperative subjects, it is difficult to observe the efforts of members, which is easy to cause poor information. Therefore, knowledge reciprocity incentive is particularly important. In this paper, the sequential reciprocity model is introduced to analyze the knowledge interaction between photovoltaic building materials enterprises, and academic and research institutions on cooperative green innovation. The results show that: (1) when the reciprocity sensitivity of academic and research institutions is large enough, academic and research institutions can feel the goodwill conveyed by the high effort level of knowledge sharing, and will reciprocate with friendly behavior. (2) When the reciprocity sensitivity of academic and research institutions is small, they will choose to pay a low level of effort in knowledge sharing. (3) When the reciprocity sensitivity of academic and research institutions is in the middle value, the higher effort level of the institutions will increase with the increase of reciprocity sensitivity of the institutions. In this paper, the sequential reciprocity model is introduced to study the reciprocity incentive effect of knowledge sharing in enterprise cooperative digital green innovation from the perspective of dynamic domain, in order to enrich the reciprocity theory and provide reference for the knowledge sharing incentive problem of enterprise cooperative digital green innovation.
