摘要
基于2000-2013年中国制造业投入服务化和企业加成率的测算构建计量模型,采用制造业企业数据实证检验制造业投入服务化对企业竞争优势的影响。结果显示:制造业投入服务化与企业加成率呈倒U型关系,中国当前制造业服务化水平总体上还处于倒U型曲线左侧,对企业加成率主要表现为正向效应;在改变估计方法、考虑潜在内生性问题、剔除关键变量极端值后进行估计,结果依然稳健。进一步的机制检验表明,成本降低是制造业服务化提高企业加成率的中介渠道。
Based on the measuring of the Chinese input servitization of manufacturing industries and firm-level price markup over the period 2000-2013,this paper put forward the econometric model to conduct an empirical study about how input servitization of manufacturing industries affect firm competitive advantage with the data of Chinese manufacturing firms.The result shows that there is an inverted U-shape relationship between the input servitization and firm's markup,and our sample is in the left side of the inverted U-shape curve,which means that the manufacturing input servitization significantly increases firm markup.This conclusion is valid in a series of robustness tests,such as changing the estimation method,considering endogenous problems and eliminating extreme values.The mechanism tests indicate that cost reduction is the possible intermediation channel to impact the firm's markup.
