产品创新如何影响企业加成率
发布时间：2018-10-23 12:20
【摘要】：本文从成本加成率角度分析企业获取创新垄断租金的微观机制,一方面,产品创新通过增加市场份额降低产品需求弹性,企业可以索要更高的加成率,即"市场份额效应";另一方面,产品创新带来的生产率提升促使企业边际成本降低,进而提升加成率,即"成本效应"。我们理论分析了"市场份额效应",并在成本加成率和生产率估计模型中考虑"成本效应",将企业创新纳入其生产率动态过程。利用2001-2007年中国工业企业数据研究验证了以下理论预期:产品创新通过增加市场份额显著提升了企业成本加成率,与此同时,产品创新也通过降低边际成本显著提升成本加成率,但"成本效应"弱于"市场份额效应"。考虑创新的自选择、测量误差和内生性问题后结论仍然稳健。
[Abstract]:This paper analyzes the micro mechanism of enterprises obtaining innovative monopoly rent from the angle of cost addition rate. On the one hand, product innovation reduces the elasticity of product demand by increasing market share, and enterprises can demand a higher addition rate. On the other hand, the productivity increase caused by product innovation leads to the reduction of marginal cost and the increase of addition rate, which is called "cost effect". We theoretically analyze the "market share effect", and consider the "cost effect" in the cost addition rate and productivity estimation model, and bring enterprise innovation into its productivity dynamic process. By using the data of Chinese industrial enterprises from 2001 to 2007, this paper verifies the following theoretical expectations: product innovation significantly increases the cost addition rate by increasing the market share, and at the same time, product innovation significantly increases the cost addition rate by reducing the marginal cost. But the cost effect is weaker than the market share effect. After considering innovative self-selection, measurement error and endogeneity, the conclusion is still robust.
