【摘要】 本文基于Katz-Bonacich中心性方法测算了1990-2015年189个国家（地区）8个制造业的全球价值链网络中心地位，将出口产品价格分离成产品质量与质量调整价格两个部分，并且从理论与实证两个层面分析与检验了二者对全球价值链网络中心地位的影响。研究发现，产业出口的产品质量提升或质量调整价格下降可以提升其全球价值链网络中心地位，但产品质量的影响比质量调整价格更稳健；产品质量和质量调整价格对全球价值链网络中心地位的提升效应在不同的产业、产品、发展程度的地区和时间段上表现出异质性，但总体上产品质量比质量调整价格更关键。机制分析表明，与质量调整价格相比，产品质量能够使得产业的出口规模更大。本文的研究有益地拓展了全球价值链地位的研究，并提出提升全球价值链网络中心地位需牢牢把握产品质量策略。更多还原

【Abstract】 The Katz-Bonacich centrality is utilized in this paper to calculate centrality of 8 manufacturing industries across 189 economies during the period from 1990 to 2015, representing the hub position in the global value chains network. The product price is decomposed into quality and quality-adjusted price, and their impacts on the centrality are analyzed both theoretically and empirically. The findings reveal that both quality upgrading and decreases in quality-adjusted price can promote the centrality position within the global value chains network, with quality emerging as the key factor. The effect of quality and quality-adjusted price on the promotion of centrality position vary across industries, products, regions with different development levels, and time periods. Overall, the quality upgrading proves to be more effective than reducing quality-adjusted price.Mechanism analysis indicates that improving quality, compared to lowering quality-adjusted prices, results in greater export levels. The research on positioning in global value chains is extended in this paper, and the quality upgrading policies to enhance a nation’s position within the global value chains network should be prioritized.更多还原
