By integrating relational embeddedness in international strategic alliance networks (ISANs) and the dynamic capability perspective, this article presents an examination of the drivers of the post-entry internationalisation commitment of small- and medium-sized enterprises (SMEs). Specifically, we investigated the mediating effect of opportunity-sensing capabilities (OSCs) on the relationship between ISAN relational embeddedness and the post-entry internationalisation commitment of SMEs. We also examined the moderating impact of strategic adaptiveness on the relationship between OSCs and post-entry internationalisation commitment. An analysis of 320 UK-based SMEs, performed using structural equation modelling, revealed that OSCs are an important mechanism through which the ISAN relational embeddedness leads to increased post-entry internationalisation commitment. Furthermore, strategic adaptiveness strengthens the positive relationship between OSCs and post-entry commitment to foreign markets. This article extends the existing SME venturing and internationalisation literature to the domain of SME post-entry internationalisation commitment.

通过整合国际战略联盟网络 (ISAN) 中的关系嵌入和动态能力视角，本文对中小企业 (SME) 进入后国际化承诺的驱动因素进行了考察。具体而言，我们研究了机会感知能力 (OSC) 对 ISAN 关系嵌入与中小企业进入后国际化承诺之间关系的中介作用。我们还研究了战略适应性对 OSC 与进入后国际化承诺之间关系的调节影响。使用结构方程模型对 320 家英国中小企业进行分析，揭示 OSC 是一种重要的机制，通过它 ISAN 关系嵌入导致增加的进入后国际化承诺。此外，战略适应性加强了 OSC 与进入后对外国市场的承诺之间的积极关系。本文将现有的中小企业风险投资和国际化文献扩展到中小企业进入后国际化承诺的领域。
