摘要

本文提出了一个综合框架，通过纳入投入弹性来评估全球价值链停滞扩张时期投入变化的影响。在Ghosh逆的框架下，将各进口部门视为一个具有随机输入偏好的完整输入需求系统，并基于二次几乎理想需求系统(QUAIDS)模型，利用输入弹性量化输入变化。新的经验证据涵盖了三个主要的区域价值链(RVC)和2010年至2020年的时间跨度，表明投入弹性的增加会导致大多数国家的产出增加，除了北美区域价值链内的国家。此外，本文还讨论了外部决定因素对投入弹性的不同程度影响，而在特定投入需求系统中，同质投入之间的替代效应可能决定其投入的竞争力。

What's the influence of input's variation? Estimating the input elasticity in the global value chain

This article presents a comprehensive framework for assessing the influence of input variation during the period of stagnant expansion of the global value chain (GVC) by incorporating input elasticity. Each import sector is treated as a complete input demand system with a stochastic preference for input in the framework of Ghosh Inverse, and the input elasticity is employed to quantify the input variation based on the Quadratic Almost Ideal Demand System (QUAIDS) model. New empirical evidence covering three major regional value chains (RVCs) and the time span from 2010 to 2020 reveals that increasing input elasticity leads to additional output for most countries, except those within the North American RVC. Additionally, this article also discusses how external determinants have diverse extents influence to input elasticity, while the substitution effect among homogenous input in the specific input demand system may decide their input's competitiveness.
