Inland Port Innovation and Firm Internationalization: A Hybrid SEM–fsQCA Analysis of Supply Chain Cognition and Institutional Dynamics
This study employs a hybrid SEM–fsQCA analysis of 372 Chinese enterprises to demonstrate that inland port innovations drive firm internationalization by enhancing supply chain resilience and cost cognition, which—alongside strengthened institutional mechanisms—foster internal and external motivations, with internal motivation proving particularly impactful through four distinct configurational pathways.

In the vast, shifting landscape of global trade, the movement of goods has long been defined by the distance between a factory and the sea. For decades, the standard model relied on coastal ports, where massive ships docked and cargo was transferred to trucks or trains for the long haul inland. However, a quieter revolution is taking place far from the ocean's edge. Inland ports—specialized hubs located deep within a country's interior—are evolving from simple storage yards into sophisticated gateways that connect local industries directly to the world. These facilities are not just about moving boxes faster; they are about changing how businesses think, feel, and decide to enter foreign markets. When a company considers selling its products abroad, it faces a complex web of concerns: Will the goods arrive on time? Will the paperwork get lost? Is the cost too high? The environment around a business, including the rules, the technology, and the reliability of its supply chain, shapes these answers. Understanding how these local improvements translate into global success is the central question driving a new investigation into the heart of regional trade.
A team of researchers set out to uncover exactly how these inland hubs influence the companies that surround them. They focused on a specific region in China, surveying 372 business leaders and managers located near inland ports in Hebei and Henan provinces. These respondents were not just random employees; they were the people making decisions about logistics, strategy, and international sales. The researchers asked them to evaluate the changes happening at their local ports, ranging from new physical infrastructure like railways and warehouses to new ways of organizing customs clearance and digital services. They also asked how these changes affected the companies' confidence in their supply chains, their perception of costs, and their willingness to expand into foreign markets. By combining two different analytical approaches, the team mapped out the journey from a local port upgrade to a company's global growth, revealing that the path is rarely a single straight line.
The study found that improvements in the physical world of the port, such as better roads, rail links, and digital tracking systems, directly strengthened a company's belief that its supply chain could withstand disruptions. When a business feels that its logistics are stable and secure, it becomes more confident in pursuing international opportunities. This sense of security acts as a springboard, encouraging the company to look outward. However, the researchers discovered a surprising nuance regarding cost. While new operational models at the ports—such as one-stop customs services and integrated logistics platforms—did successfully lower the perceived cost of doing business, this reduction in price alone did not automatically trigger a desire to expand internationally. Lower costs are helpful, but they are not the sole driver. A company might save money on shipping but still hesitate to enter a foreign market if it lacks the internal drive or the strategic readiness to do so.
The role of government and institutional support proved to be equally complex. The study distinguished between three types of support: formal rules and policies, professional standards and norms, and the shared understanding of how international trade works. The researchers found that while new policies and regulations at the ports were quickly noticed, they did not, on their own, create a strong internal desire to expand. Instead, it was the shift in professional norms and the growing shared belief among local businesses that "going global" is a legitimate and achievable goal that truly fueled internal motivation. When a business sees its neighbors and peers successfully navigating international trade, and when the local environment makes that path feel familiar and accepted, the company's own leadership becomes more committed to the effort. This internal commitment, the willingness of the management team to allocate resources and take risks, emerged as the most powerful predictor of actual international success.
To understand the full picture, the researchers looked beyond simple cause-and-effect relationships to see how different factors combine to produce results. They identified four distinct pathways that lead to high levels of international growth, showing that there is no single formula for success. One path involves a company that feels its supply chain is rock-solid and has a strong internal desire to grow. Another path shows that a company can succeed by aligning strong external opportunities with its own internal readiness. A third, perhaps more surprising, route revealed that a company can achieve high growth through efficient operations and cost savings, even if the institutional support from the government is not yet fully developed. The fourth path is a comprehensive approach where strong infrastructure, efficient services, and high confidence in logistics all work together to drive expansion. These findings suggest that inland ports are not just logistical tools but dynamic platforms that can support internationalization in multiple ways, depending on the specific strengths and circumstances of the businesses they serve.
Ultimately, the research paints a clear picture of how local innovation ripples outward to create global opportunities. The physical upgrades to inland ports build confidence in the reliability of the supply chain, while the evolution of services and norms builds the cultural and strategic readiness needed to cross borders. The study confirms that while external conditions like better ports and lower costs are necessary, they must be translated into an internal commitment by the firm itself to truly succeed. For the managers of these inland hubs, the lesson is that investment must go beyond concrete and steel; it must include the creation of an environment where international trade feels normal, supported, and understood. For the businesses themselves, the takeaway is that the gateway to the world is often built right in their own backyard, but walking through it requires a mix of logistical trust and strategic courage. The journey from a local port to a global market is not a straight line, but a series of interconnected steps where confidence, culture, and capability meet to open new horizons.
