中国制造业企业利润决定机制研究——基于异质性生产率的视角

基于异质性生产率角度提出决定企业利润的数量模型,使用中国制造业企业样本数据研究企业的利润状况,并且提出衡量企业利润状况的两种利润率,即销售利润率与投资利润率,最后实证检验生产率对企业利润的决定作用。研究结论显示:中国制造业企业的投资利润率具有逐渐提高的趋势,而销售利润率却具有逐渐下降的趋势;企业生产率与其利润规模呈显著的正相关关系,并且具有相同生产率的企业选择进入出口市场会获得更高的利润。

Profiting Mechanism of Chinese Industrial Enterprise:Based on Heterogeneous Productivity

From the perspective of heterogeneity of productivity,this paper proposes a quantitative model to decide corporate profits,researches a firm’s profit by using sample data of China’s manufacturing,puts forward two conditions to measure a firm’s profits margins,the profit margin on sales and investment,and empirically tests productivity of corporate profits in the decision.It has concluded that:profit margin of China’s investment in manufacturing firms gradually increase,and sales profit margin is with a gradually downward trend;corporate profits and their productivity scale show a significant positive correlation,and companies of same productivity enjoy higher profits if they have access to export markets.
