Abstract: Construction workers in China are confronted with a series of challenges including imbalanced age structure, disordered labor mobility, low levels of professional skills, inadequate protection of rights and interests, and a lack of a unified market. They are unable to meet the needs of high-quality development in China’s construction industry, necessitating a transition towards an industrialized workforce. Against the backdrop of information technology driving high-quality development across various sectors, the construction industry is actively exploring the use of information technology to manage construction workers and enhance their professionalism. Existing studies have delved into various aspects of the industrialization of construction workers. Some studies have recognized the importance of sharing information about construction workers and have proposed recommendations for integrating and sharing construction worker information through a unified platform. However, overall, there is limited research exploring the impact of information sharing on the industrialization of construction workers. As a result, there is a lack of theoretical support to accelerate the promotion of information management, a crucial measure for cultivating a new era workforce in the construction industry. This restriction, in turn, hampers the industrialization process of construction workers.
   Evolutionary game theory overcomes the human rational hypothesis, and is applicable to various research problems under conditions of incomplete information. It has been widely used to study the formation process of social norms, and institutions or systems. To bridge the research gap of the industrialization of construction workers in China, this paper constructs an evolutionary game model among construction workers, construction labor subcontractors, and construction contractors, and analyzes the evolutionary stable equilibrium points of the model, stability judgments and stability conditions of each equilibrium point based on the second method of Liapunov. Furthermore, four representative game scenarios are simulated using numerical simulation methods. From the evolution path of the simulation model, the impact of information sharing on the behavior of players such as construction workers, construction labor subcontractors and construction contractors are further clarified.
   The research findings demonstrate that information sharing plays a decisive role in the industrialization process of construction workers. In the absence of information sharing, neither the group of construction labor subcontractors nor the group of construction workers evolves autonomously into stable states of specialized enterprises and professionalized workers. Only with information sharing, under specific initial conditions, does the system stabilize into an equilibrium state. Here, construction contractors choose to share information, construction labor subcontractors opt for specialized development, and construction workers pursue professional development. Additionally, based on the analysis of key influencing factors, the stability of the system is also influenced by factors such as the information sharing costs of construction contractors, the quality benefits of construction contractors, and income disparities among construction labor subcontractors. Specifically, reducing the cost of information sharing for construction contractors, increasing their quality benefits, and raising income disparities among construction labor subcontractors can reduce the restrictions on the initial conditions and accelerate the rate of evolution.
   Based on the research conclusions, the paper also puts forward policy suggestions to promote the development of the construction industrialization workforce, such as reducing information sharing costs, establishing quality-based incentive mechanisms, building construction contractor alliances, and establishing incentive mechanisms based on the level of construction operations.

摘要： 信息共享对于劳动力市场机制具有重要影响,然而探讨其对我国建筑劳务市场主体行为影响机理的研究较少,这导致通过实施建筑工人信息共享推动建筑产业工人队伍建设缺乏理论指导。通过构建由施工企业、劳务企业和建筑工人构成的演化博弈模型,研究了信息对于各方行为的影响与作用机制,并采用仿真分析了多情景下的博弈演化路径及关键因素对系统均衡状态的影响。研究表明,降低信息共享成本、提高施工企业质量收益、加大劳务企业收入差异、改善建筑工人绩效收入,能够促使施工企业参与信息共享,消除市场的信息不对称,激励劳务企业向专业化转型,并促进建筑工人的职业化发展。最后从降低信息共享成本、建立基于质量的激励机制、建立施工企业联盟、建立基于作业水平的激励机制等方面为推进建筑产业工人队伍建设提出政策建议。
