本文基于扩展的M-O模型,提出了出口企业阶段性“低加成率陷阱”现象。通过引入产品质量,对这一现象的微观机制进行了深入探索。本文认为,企业低加成率出口正是较低生产率水平下“最优出口产品质量选择”所带来的一种阶段性现象,采用中国工业企业数据和海关交易数据进行的经验研究结果显示:中国出口企业普遍处于“低加成率陷阱”区间;出口企业加成率关于生产率的“U型”曲线的门槛值约为6.93,约25%的企业已经跨越了“低加成率陷阱”区间;东部企业面临的“质量升级效应”更强烈,“质量升级”意愿较强;中国具有比较优势的劳动密集型行业更多处于“低加成率陷阱”区间,而技术密集型行业出口负向影响相对较弱。
Based on the extended M-O model, this paper puts forward the phenomenon of export enterprises stage “low bonus rate trap ”. Through the introduction of product quality, the microscopic mechanism of this phenomenon has been explored in depth. This paper argues that the low-rate-of-business export is just a phased phenomenon brought about by the “optimal export product quality selection” under the low productivity level. The empirical research results based on the data of China’s industrial enterprises and the customs transaction data Shows that: Chinese export enterprises are generally in the “low rate of increase trap” interval; Export enterprises on the rate of productivity on the “U” curve threshold is about 6.93, about 25% of the enterprises have crossed the Low rate of increase of the trap “interval; eastern enterprises are facing ” quality upgrade effect “more strongly, ” quality upgrade “strong will; more labor-intensive industries with comparative advantages in China are more in Rate-trapped ”interval, while exports from technology-intensive industries have a relatively negative impact.
