Dissertation Summary

This study confirms that improving firm performance in Indonesian construction companies can no longer rely on conventional approaches; rather, it requires a strategic transformation integrating operational capabilities, relational capabilities, and business model innovation. Within an industry context characterized by economic contraction, global supply chain disruptions, and increasingly complex environmental dynamics, firms are required to strengthen their internal foundations before leveraging external factors.

Empirically, lean construction and supply chain resilience are found to have positive and significant effects on firm performance. This indicates that operational efficiency and supply chain robustness constitute essential prerequisites for maintaining business sustainability and stability in the construction sector. However, their impact becomes more optimal when transformed through business model innovation. These findings underscore the role of business model innovation as a transformational mechanism that links internal capabilities to enhanced value creation and competitive advantage.

Meanwhile, strategic partnership does not exert a direct and significant effect on firm performance. Nevertheless, when mediated by business model innovation, strategic partnership demonstrates a significant and positive impact. This suggests that interorganizational collaboration generates strategic value only when translated into adaptive business model renewal, rather than functioning merely as contractual relationships.

Furthermore, environmental dynamism is shown to significantly strengthen the relationship between business model innovation and firm performance. The higher the level of environmental dynamism, the greater the urgency of business model innovation as a strategic response. Thus, innovation is no longer optional but constitutes a fundamental necessity in addressing industry uncertainty.

Overall, this study concludes that business model innovation serves as a key variable—or strategic catalyst—that integrates operational efficiency (lean construction), supply chain resilience, and external collaboration (strategic partnership) into enhanced firm performance. Therefore, construction companies in Indonesia should prioritize strengthening their internal foundations and transforming them through adaptive and sustainable business model innovation to remain resilient and competitive in a dynamic environment.
