This paper aims to examine the effect of agglomeration on firm level productivity in Iran’s food manufacturing by employing a firm level dataset during 1986–2015 among firms for four districts. The empirical results show that agglomeration in north districts are key factors in productivity growth. In this work, we apply a spatial Bayes model that uses hierarchical techniques during the three terms. The productivity clustering map is able to capture such patterns as the high productivity area that appears in the south, north districts of Iran. This paper evaluates the effect of agglomeration on firm productivity in Iran’s food industries at district level. We find that regional market potential is the strong predictor of productivity; moreover, industrial agglomeration has a productivity-augmenting impact.

产业集聚对生产力的影响：来自伊朗食品工业的证据

本文旨在通过在 1986-2015 年期间在四个地区的企业中采用企业级数据集来研究集聚对伊朗食品制造业企业级生产力的影响。实证结果表明，北部地区的集聚是生产力增长的关键因素。在这项工作中，我们应用了一个空间贝叶斯模型，该模型在三个术语中使用了分层技术。生产力聚类图能够捕捉到出现在伊朗南部、北部地区的高生产力区等模式。本文在地区层面评估了集聚对伊朗食品工业企业生产力的影响。我们发现区域市场潜力是生产力的有力预测指标；此外，工业集聚具有提高生产力的影响。
