The objective of this study is to analyse the effect of four export barrier groups – human capital, cultural, administrative, and financial – on the product export barrier. The study participants constitute a statistically significant sample of 318 exporting companies in Brazil. The research model is tested using structural equation modelling, specifically the partial least squares (PLS-SEM) technique, and SmartPLS version 3.2.9. The results confirm that there is a significant effect of three export barriers – human capital, cultural, and financial – on the product export barrier. The effect of the administrative barrier on the product barrier is not verified. Besides, the effects of the human capital barrier on the cultural barrier and the administrative barrier on the financial barrier are verified. The mutual interaction between export barriers makes it advisable to manage each type of barrier.

本研究的目的是分析四个出口壁垒组——人力资本、文化、行政和金融——对产品出口壁垒的影响。研究参与者构成了巴西 318 家出口公司的统计显着样本。研究模型使用结构方程建模，特别是偏最小二乘法 (PLS-SEM) 技术和 SmartPLS 3.2.9 版进行测试。结果证实，三个出口壁垒——人力资本、文化和金融——对产品出口壁垒有显着影响。行政壁垒对产品壁垒的影响未得到验证。此外，验证了人力资本壁垒对文化壁垒和行政壁垒对财务壁垒的影响。
