全球价值链网络中心地位提升的关键因素：质量或价格

doi:10.16381/j.cnki.issn1003-207x.2021.2036

Abstract

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.

Key words: global value chains network, Katz-Bonacich centrality, quality, quality-adjusted price
