The impact of customs and trade regulations on the operations of African firms
利用世界银行企业调查数据，研究非洲企业将海关和贸易法规视为运营障碍的程度，发现从事国际业务的小企业较少报告此类障碍，而认为腐败和政治不稳定是障碍的企业则更易受其影响。
This paper uses data from the World Bank Enterprise Surveys to investigate the extent to which customs and trade regulations are perceived to be an obstacle to the operations of establishments in Africa. It examines variations in responses to a question on the impact of customs and trade regulations in establishments across a range of African countries and investigates the factors that determine the observed differences. The regression models focus particularly on three sets of influences. The results indicate that small establishments that engage internationally are less likely to report customs and trade regulations as an obstacle. In contrast, such obstacles were deemed to be more severe in establishments that also considered corruption and political instability to be obstacles. This was also generally the case for establishments located in lower income countries.
