Simulation Research On Low-carbon Cooperation Behavior Of Construction Supply Chain Subject Based On Complex Network Evolutionary Game

The construction industry is an industry that emits a lot of energy.From brick by brick to the construction of high-rise buildings,every link is generating a lot of carbon emissions.Nowadays,research on low-carbon emission reduction in the construction industry is mainly focused on the development of low-carbon building materials and low-carbon technologies.However,as the number of participants in the construction industry gradually grows,there are complex and diverse interest relationships,which are relevant to the efficiency and effectiveness of low-carbon implementation.None of them are ideal.In order to achieve China's low-carbon goal of peaking carbon dioxide emissions in 2030,it is not enough to rely on a single company or a supply chain main body to carry out low-carbon emission reduction.The main body of the construction supply chain needs to cooperate to reduce carbon emissions.The low-carbon cooperation behavior of the main body of the construction supply chain reflects a certain degree of importance.Based on the basic theory and a comprehensive review of the literature results of domestic and foreign scholars,this paper first analyzes the low-carbon behavior of the main body of the construction supply chain and the low-carbon cooperation relationship of the main body of the construction supply chain,and then uses the citespace knowledge graph theory to analyze the construction The literature related to the low-carbon cooperation behavior of supply chain entities was retriev ed,sorted and analyzed,and the main influencing factors of the low-carbon cooperation behavior of the construction supply chain entities were summarized,including benefit distribution,penalty for breach of contract,synergy,and low-carbon spillover effects.Secondly,an evolutionary game model of low-carbon cooperation behavior in the construction supply chain is established.The main body of the construction unit and the main body of the construction unit are the representatives of the main body of th e construction supply chain.The game relationship and equilibrium strategy between the two are studied,and the evolutionary stability strategy is related.Analysis.Theoretically,it proves the necessity of low-carbon cooperation between the upstream and downstream entities of the construction supply chain,and provides a theoretical basis for constructing the complex network evolution model of low-carbon cooperation behavior of the construction supply chain entities.Finally,based on the scale-free network,the network evolution model of low-carbon cooperative behavior of construction supply chain subjects is constructed,and the influence factors of low-carbon cooperative behavior of construction supply chain subjects on the network evolution are studie d.According to the research results of network evolution,it is concluded that strong synergy,moderate default punishment mechanism and reasonable benefit distribution all play a positive role in the low-carbon cooperation behavior of the main body of co nstruction supply chain;In the process of low-carbon cooperation,the main body of construction supply chain should pay attention to the influence of low-carbon spillover effect on cooperation behavior,improve the coefficient of low-carbon spillover effect in small-scale network,and control the coefficient of low-carbon spillover effect in a reasonable range in large-scale network to promote low-carbon cooperation among the main bodies of construction supply chain.The complex network game model of the l ow-carbon cooperative behavior of the main body of the construction supply chain constructed in this paper focuses on the study of the influence factors of the main body of the construction supply chain on the evolution of the network,and proposes relevan t suggestions for the main body of the construction supply chain to conduct low-carbon cooperation,Improve the enthusiasm of the main body of the construction supply chain to participate in low-carbon cooperation,and promote the optimization of low-carbon cooperation between the main body of the construction supply chain.
