规模异质性与集聚拥挤效应

Scale heterogeneity of enterprises and crowding effect of industrial agglomeration

产业集聚到一定程度会出现负面效应——拥挤效应,近些年学术界对此已开展了相关研究。本文基于企业规模异质性视角,以浙江省纺织业为例,通过构建企业生产率影响模型,分析企业规模对集聚拥挤效应的影响。结果表明:在规模经济有效的情况下,企业规模异质性对集聚具有正向影响;当出现规模不经济时,企业规模异质性对集聚拥挤效应具有负面影响。本文最后针对不同规模类型企业,提出了改善集聚拥挤效应的对策建议。

Industrial agglomeration,to a certain extent,will cause a negative effect-crowding effect,and in recent years,the academic community has carried out relevant research on this topic. Based on the perspective of enterprise scale heterogeneity,this paper takes the textile industry in Zhejiang Province as an example,analyze the influence of enterprise scale on agglomeration crowding effect through constructing the enterprise productivity influence model. The results show that,when the scale economy is effective,enterprise scale heterogeneity has a positive impact on the crowding effect of industrial agglomeration. When the scale economy fails to appear,enterprise scale heterogeneity has a negative impact on agglomeration crowding effect. At the end of this paper,we put forward some countermeasures and suggestions to improve the crowding effect of enterprises with different scales.
