产业集群对企业业绩增长的影响具有两面性,而集聚正(负)外部性对企业业绩增长的作用效果会受到企业自身因素的影响。基于企业异质性视角,运用中国工业企业数据库,实证检验了产业集群对异质企业业绩增长的影响,并应用分位数回归法,考察了产业集群对异质企业业绩增长的影响随企业业绩增长率的变化趋势。结果发现,总体上,企业业绩增长明显受益于MAR外部性与Jacobs外部性;企业资本深化度与本土根植性水平越高,MAR外部性与Jacobs外部性对企业业绩增长率的促进效果越明显;随着企业业绩增长率的提升,MAR外部性与Jacobs外部性对于高资本深化度与强本土根植性企业业绩增长的促进效果呈现出增强的趋势;低业绩增长率企业的资本深化度越高其拥塞效应越显著。
The effect of industrial clusters on corporate performance growth has two sides, and the effect of positive (negative) externalities on corporate performance growth will be affected by the enterprise’s own factors. Based on the perspective of enterprise heterogeneity, using the database of Chinese industrial enterprises, this paper empirically tests the impact of industrial clusters on the performance growth of heterogeneous enterprises, and uses the quantile regression method to examine the impact of industrial clusters on the performance growth of heterogeneous enterprises. The trend of growth rate. The results show that, overall, the growth of corporate performance obviously benefits from MAR externality and Jacobs externality; the higher the level of corporate capital deepening and local rootedness, the more obvious the effect of MAR externality and Jacobs externality on corporate performance growth; With the growth of business performance, MAR externality and Jacobs externalities have shown an increasing trend toward the promotion of high-capital deepening and strong local-rooted business performance growth. The low-performance growth rate of firms deepens their capital The more obvious the congestion effect.
