科学的建筑供应链知识共享机制对实现建筑工业化进程中的知识创新与增值具有重要意义。运用演化博弈理论研究有限理性下的工业化建筑供应链知识共享机理，构建知识共享演化博弈模型，分析系统演化路径、演化稳定策略及其影响因素的作用机理。结果表明：建筑企业知识共享行为的演化具有路径依赖性，存在均共享与均不共享两个演化稳定策略，企业采取知识共享策略的概率与惩罚成本、知识吸收与收益能力以及共享激励强度正相关，与共享成本负相关，合理的惩罚成本有助于约束机会主义行为，并通过数值分析验证了结论的正确性。%The knowledge-sharing mechanism of construction supply chain(CSC)is of great significance for knowledge innovation and increment in the process of construction industrialization in China. Evolutionary games theory was used to study the knowledge-sharing mechanism of industrialized CSC under the condition of bounded rationality. The evolutionary path,stable equilibrium strategy,and the mechanism of influencing factors were analyzed by establishing evolutionary game model. The results indicate that knowledge-sharing behaviors have the characteristics of path dependence and two evolutionary stable strategies (sharing and non-sharing)exist. The probability of knowledge-sharing in CSC has a positive correlation with punishment cost, knowledge absorption and profit ability,and sharing incentive intensity,and has a negative correlation with sharing cost. The punishment cost in reasonable level could help to reduce opportunistic behaviors. The numerical analysis was carried out to verify the conclusions.
