Given the importance of entry promotion to prompt economic growth and promote structural transformation, this paper investigates the regional determinants of firm entry in the 30 Iranian regions, considering four different sizes—micro, small, medium, and large—over 2000–2015. Using a new and unique database, we estimate different spatial econometric models, which take into account three types of spatial interaction effects. We find that firm entry is related to some regional characteristics, but the relationship is not homogeneous across firms of different size. We also find that most types of firms are influenced by the negative effect of economic sanctions during the sample period.

考虑到进入促进对促进经济增长和促进结构转型的重要性，本文研究了伊朗30个地区的企业进入的区域决定因素，考虑了2000-2015年间的四种不同规模（微观，小型，中型和大型）。使用一个新的独特数据库，我们估计了不同的空间计量经济学模型，其中考虑了三种类型的空间相互作用效应。我们发现企业进入与某些区域特征有关，但不同规模企业之间的关系并不相同。我们还发现，在样本期内，大多数类型的公司都受到经济制裁的负面影响。
