Spillovers from high growth firms: evidence from Hungary
利用匈牙利行政微观数据，研究发现高增长企业能提升同行业及下游供应商行业的生产率，中等生产率水平的企业受益最大，且结果不受空间聚集程度或企业年龄、出口状态影响。
Abstract How do high-growth firms (HGFs) affect the rest of the economy? We explore this question using Hungarian administrative microdata. Relying on the Birch definition of HGFs, we find evidence for stronger productivity growth for firms operating in industries with more HGFs and for firms supplying industries with more HGFs. Knowledge spillovers or the surge of HGFs’ demand for intermediate inputs could explain these positive associations. Firms with intermediate productivity levels seem most likely to benefit from this effect, while we find no differences by age or export status. The results hold irrespective of the level of spatial aggregation and are robust to alternative definitions of HGFs as well as different measures of productivity or spillover.
