| 中文摘要: |
| 研究目标：测算衡量生产分割程度的生产阶段数，探讨刻画全球价值链分工程度的生产分割对企业加成率的微观影响与作用机制。研究方法：采用DLW法测算中国企业加成率，选用固定效应模型分析全球价值链分工对企业加成率的影响，并构建工具变量法缓解内生性。研究发现：企业选择全球生产分割、国际生产分割与国内生产分割方式显著提高了企业加成率。全球生产分割方式显著提升了低生产率企业、高技术企业、民营企业加成率，尤其是低生产率企业选择国际生产分割、高技术企业选择国内生产分割。生产分割一定程度上抵消了出口企业与内销企业因“竞争效应”导致的低加成率。另外，企业“技术进步效应”和“交易成本效应”是生产分割促进企业加成率提升的两个可能的渠道。研究创新：丰富和拓展了全球价值链分工影响企业加成率的文献，从企业异质性、行业技术异质性以及结构性视角进行稳健性分析，并通过中介效应模型验证影响机制。研究价值：这些重要发现对破解中国企业“低加成率陷阱”、提升企业全球价值链分工具有重要的启示意义。 |
| 英文摘要: |
| Research Objectives: We measure the number of production stages that reflect the degree of production segmentation, which characterizes the division of labor in the Global Value Chains (GVCs), and further verify its micro effect and mechanism on firms' markups. Research Methods: We use the DLW method to measure firms' markups, design a fixed-effect model to analyze the impact of the GVCs division of labor on it, and construct an IV to alleviate endogenous problems. Research Findings: The participation of enterprises in the global production segmentation, international production segmentation and domestic production segmentation has significantly increased firms' markups. Global production segmentation has significantly increased the markups of low-productivity, high-tech, and private enterprises, especially low-productivity enterprises participating in international production segmentation, and high-tech enterprises participating in domestic production segmentation. The production segmentation partly offsets the low markups caused by the “competitive effect” of export and domestic companies. In addition, “technical progress effect” and “transaction cost effect” are two possible channels for production segmentation to increase the firms' markups. Research Innovations: This paper enriches and expands the literature of GVCs division of labor influencing firms' markups. We analyze the robustness from the perspective of firm heterogeneity, industry technical heterogeneity and structural perspective, and verify the impact mechanism through the intermediary effect model. Research Value: These important findings have important implications for cracking down on the “Low Markups Trap” and improving GVCs of firms. |
