We contend that the Uppsala internationalisation process (IP) Model offers the basis, yet unrealised, for a process theory of growth of the internationalising firm. From the Model’s origins, particularly in Penrosean theory, we develop this potential by offering a theory extension that explicates the organisational changes within the firm required to sustain international growth. This repositioning distinguishes us from previous attempts to amend, supplant or extend the IP Model. In developing the theory extension, we specify how we remain faithful to the IP Model’s behavioural assumption ground. We provide a model of the internationalising firm that posits non-linear growth paths. This is due to the challenges of synchronising the external opportunity seeking of the firm as it expands internationally with the internal capacity building required to realise these opportunities. Introducing to the IB field this asynchronicity problem, an absence of temporal concurrence, we show its potential in explaining organisational changes and discontinuities in the internationalising firm’s development as it seeks to grow. By extending the IP Model to offer a theory of growth of the internationalising firm, we provide the basis for further process scholarship on this topic that addresses contemporary concerns and developments.

我们认为，乌普萨拉国际化过程（IP）模型为国际化公司成长的过程理论提供了基础，但尚未实现。从模型的起源，特别是在彭罗斯理论中，我们通过提供理论扩展来开发这种潜力，该理论扩展阐明了维持国际增长所需的公司内部的组织变革。这种重新定位使我们有别于之前修改、取代或扩展知识产权模型的尝试。在发展理论扩展的过程中，我们具体说明了我们如何保持对知识产权模型行为假设基础的忠诚。我们提供了一个国际化公司的模型，该模型设定了非线性增长路径。这是由于公司在国际扩张过程中寻求外部机会与实现这些机会所需的内部能力建设同步面临的挑战。通过向 IB 领域引入这种异步性问题（即时间上缺乏并发性），我们展示了其在解释国际化公司在寻求成长过程中的组织变化和发展中的不连续性方面的潜力。通过扩展知识产权模型以提供国际化公司的增长理论，我们为解决当代问题和发展的这一主题的进一步学术研究提供了基础。
