Abstract
Sustainable development has become the development goal of all countries worldwide. Promoting green buildings in sustainable development is important to promote environment-friendly development. Considering this, we used the multi-player quantum game method to analyze the interest relationship between the developer, general construction contractor, and building materials supplier for the development of green-building and discussed the influence of the three on the game system. Furthermore, this study proposes a novel three-person quantum game model, discusses the optimal strategy selection process of the three parties with and without considering the entanglement, and uses a practical engineering case to prove the effectiveness of the proposed method. Without considering the entanglement of states, developers have the lowest willingness to invest in green-building, that is, the minimum investment of 28 million. When entanglement of states is considered and the initial state is ψini=Ĵ000, developers have the highest intention to invest in green buildings, that is, 56 million. Compared with the initial state of ψini=Ĵ111 when entanglement of states is not considered and entanglement of states is considered, developers' intention to invest in green-building shows an upward trend. The results show that entanglement can effectively prevent betrayal in the process of green-building construction. Finally, according to the meaning of quantum entanglement and quantum strategy, an “entanglement treaty” is constructed, aiming at reducing the occurrence of treachery and providing an important guarantee for encouraging green-building participants to actively participate in green-building development. This study provides a decision reference for promoting green-building construction. The proposed method is also applicable in other fields.
