The data was analyzed using partial least square structural equation modeling (PLS-SEM). The results reveal that customer engagement through digital channels and feedback frequency significantly influence the speed of innovation, while the direct effect of participation in co-creation activities is not significant.

It considers the relationships between green innovation and cost performance, supplier trust, government legitimacy and public reputation. By analyzing both cross-sectional and longitudinal data, the results reveal that technological opportunism significantly contributes to green innovation adoption, with government support amplifying this effect. The interaction effect of air quality, however, presented contrasting results. While technology-sensing capability positively influences green innovation in low-pollution contexts, its effect diminishes in high-pollution scenarios. Conversely, technology-response capability has an insignificant positive effect on green innovation when air pollution is low but a significant positive effect when air pollution is high.

Absorptive capacity, measured by the ratio of research and development expenses to total revenue, has a significant positive direct impact on both innovation and financial performance. However, innovation, represented by the natural logarithm of total intangible assets, has a negative influence on financial performance and mediates the positive relationship between absorptive capacity and financial performance.

Therefore, Construction 4.0, as the digital transformation of construction companies in the era of Industry 4.0, attracts the attention of both practitioners and researchers. This empirical study aims to uncover the complex relations among Construction 4.0, Business Model Innovation (BMI), and firm performance in a developing country context. We propose an original model of relations purporting that BMI mediates the positive effects of Construction 4.0 on firm performance, drawing mainly on the dynamic capabilities view. All statistical analyses were performed by using R statistical language. Data was gathered from 152 managers in the Turkish construction sector via the convenience sampling method. Descriptive statistics, validity, reliability, correlation, and PROCESS mediation analyses were used to test research hypotheses. The results show that both digital and physical layers of Construction 4.0 positively relate to firm performance and that BMI fully mediates this positive relation.
