| In order to improve the level of BIM technology and support the structural modernization and digital transformation of the Chinese construction industry,the cooperation between construction companies and BIM companies to develop BIM research and development is an important cooperation model that effectively promotes and maintains BIM technology innovation.At the same time,to encourage innovation,the government is Encourage and even participate in cooperative innovation activities while improving the innovation environment.In the process of cooperative research and development of new BIM technologies,there are market sharing,technology integration,management coordination,as well as opportunism and moral hazards.Construction companies and BIM companies face the risk of cooperative research and development,which will weaken the motivation of companies to carry out BIM technology cooperation research and development.Affect the effect of cooperation.In order to ensure the healthy,stable and orderly development of the cooperative R&D relationship between construction companies and BIM companies,while considering the role of the government as a regulator of technological innovation activities,it is necessary to cooperate with both parties under the conditions of reasonable consideration of relevant influencing factors.And the evolution of government participation in cooperative games.Based on this background,the main research of this article is as follows: First,it analyzes the cooperative R&D relationship between construction companies and BIM companies,determines key influencing factors,and uses evolutionary game theory to establish a BIM cooperative R&D model between construction companies and BIM companies without government participation.Then the stability analysis,path evolution analysis and parameter simulation analysis are carried out on the model.Secondly,on the basis of the former,the government is introduced,with construction companies,BIM companies and the government as the main game player,and the evolutionary game theory is used to analyze the evolution process of BIM cooperative R&D behavior under government participation.Using simulation software,according to the actual situation and the basic assumptions of the model,further analyze the influence of each influencing factor on the stable point and evolution path.Based on the research conclusions,certain suggestions are made to relevant enterprises and government departments,in order to provide certain references for promoting the cooperative research and development of BIM technology.The research conclusions of this paper are as follows: with the participation of the government,the greater the proportion of the initial choice of cooperation between construction enterprises and BIM enterprises,the greater the possibility of the evolution to collaborative research and development;Increasing the synergistic coefficient and knowledge transfer efficiency and reducing the BIM R&D cooperation cost can effectively promote the cooperative research and development of cooperative subjects.Reducing the risk of joint research and development and independent research and development will be beneficial to promote the joint research and development of enterprises of both sides.The liquidated damages and reputation loss of BIM enterprises promote the stable development of construction enterprises and BIM enterprises through negative incentives;The weaker the learning and conversion ability of construction enterprises and BIM enterprises to each other’s invested resources,the less obvious the knowledge spillover effect is,and the more stable the cooperation system is.The distribution of income according to work or the equal sharing of income between construction enterprises and BIM enterprises can effectively promote the joint research and development between them.In the case of government participation in innovation,the participation of government has an obvious promoting effect on the evolution of cooperation between construction enterprises and BIM enterprises.Government subsidies and supervision in BIM research and development need to be formulated according to the actual situation,too large is not conducive to the evolution of the three parties(cooperation,cooperation and participation);Increasing the fines of the government helps to maintain the stability of the(cooperation,cooperation,participation)strategy;The higher the revenue growth rate is,the more likely the construction and BIM enterprises will evolve toward cooperation. |
