Enhancing building energy efficiency: Formation of a cooperative digital green innovation atmosphere of photovoltaic building materials based on reciprocal incentives

A good innovation atmosphere between photovoltaic building materials manufacturing enterprises and universities and scientific research institutions is conducive to the effective development of a cooperative digital green innovation process. This paper establishes an evolutionary game model for the formation of a cooperative digital green innovation atmosphere in photovoltaic building materials manufacturing enterprises under two mechanisms: direct and indirect reciprocity. The results show that both direct and indirect reciprocity mechanisms are conducive to the formation of a cooperative digital green innovation atmosphere for photovoltaic building materials manufacturing enterprises. This study provides theoretical guidance for photovoltaic building materials manufacturing enterprises to cultivate a cooperative digital green innovation atmosphere.
