Identification of Export Financing Dimensions for Technical and Engineering Services in the Field of Transport Infrastructure under the Buyer’s Credit Scheme

Export financing for technical and engineering services in infrastructure projects, particularly in transportation infrastructure, has become a critical area of focus for policy-makers. The buyer’s credit scheme is one of the primary financial mechanisms that enhances the global competitiveness of Iranian contractors. However, due to its novelty in Iran and a lack of comprehensive understanding of its dimensions, this scheme has not achieved its full potential, leading to inefficiencies in foreign exchange resource allocation. This study aims to bridge this gap by identifying the key dimensions of export financing for transportation infrastructure projects under the buyer’s credit scheme. By employing a mixed-methods approach, this research integrates qualitative insights from expert interviews (analyzed using thematic analysis in MAXQDA) with a quantitative validation process using structural equation modeling (SEM) in Smart PLS. The findings reveal five global themes, eleven organizing themes, and twenty-three key indicators, forming a comprehensive framework for evaluating and optimizing buyer’s credit schemes. This research contributes to the field by offering a structured model that enhances the effectiveness of export financing strategies. The findings provide actionable insights for policy-makers and practitioners to refine financial policies, mitigate risks, and strengthen Iran’s position in international infrastructure markets.
