In an era of knowledge economy, most construction enterprises are adopting technology alliances to address increasingly serious environmental issues and severe market rivalry. Despite the rapid development of such alliances, there is a high failure rate, how to evaluate the sustainability of construction enterprises technology alliances (CETA) is relatively lacking. However, distinct from other alliances, technology alliances are dedicated to knowledge diffusion and innovation, it’s more insightful from a knowledge perspective to analysis sustainability. Thus, based on knowledge viewpoint, this study builds a Bayesian Belief Network (BBN) model for assessing the sustainability of CETA, aiming to construct a scientific evaluation framework encompassed four dimensions, focusing on environmental, economic, social, and relational. The results indicate that: (1) Integrating of various theories, the constructed evaluation framework provide a comprehensive measure of the overall sustainability for CETA; (2) Knowledge spreads through construction activities, socioeconomic events and alliance network building; (3) The environmental sustainability is most significant for CETA, and green innovation plays an effective transmission effect, driven by green motivation, to promote the growth of green benefits. Moreover, the shared vision and asset specificity are the most important in relational sustainability. Additionally, cost feasibility and health and safety play a crucial role in economic sustainability and social sustainability, respectively .
