摘要
本文采用第三次全国工业普查521个制造业行业近60万个企业的系统数据,深入考察了中国制造业集中与利润率之间的关系。分析结果表明,中国制造业集中度与行业利润率之间存在着一种正相关关系,即中高集中产业利润(税)率要远高于低集中产业。但是,这种关系并非完全是线性的、连续的和单调的,它受到许多因素的综合影响和扰动。在此基础上,笔者对中国制造业行业利润率差异进行了初步的解释。
By using of the data of The Third National Industrial Census in 1995,this paper examined concentration and profit rate of 521 manufacturing industries in China's Mainland.We found that there exists a positive correlation between concentration and profit rate.That is to say,the profit rate of midhighly concentration industries is higher than that of lowly concentration industries.However,that positive correlation isnt entirely linear,continuous and flat,and many factors may affect its change.
