中美产品特征对产业升级作用机制的比较研究——基于产品空间理论视角

A Comparative Research on the Effect of Product Features on the Industrial Upgrade between USA and China——Empirical Analysis Based on the Product Space Theory

基于产品空间理论视角,选取1962-2013年中美出口贸易数据,从微观产品特征视角对比分析了中美两国产品特征对产业升级的作用机制。研究表明:产品特征在产业升级与发展过程中发挥双重作用机制,即产业升级与发展不仅取决于现有产品积累的要素禀赋,还受到产品本身技术复杂性的影响。在产业升级与发展过程中,中国主要依赖产品密度(DEN),即依赖于既有产品积累的要素禀赋实现渐进式发展,很难实现跨越式发展,而美国在产业升级与发展过程中,产品密度(DEN)与产品技术复杂性(PCI)同时发挥了积极的双重作用并促进新竞争优势形成。进一步研究表明,密度(DEN)和产品复杂度指数(PCI)在不同产业升级过程中的作用机制存在差异。通过对比研究中国改革开放前后两个阶段发现,随着生产要素禀赋积累以及产品技术复杂性提高,产业升级的支撑作用增强,抑制作用减弱,但是引领作用不足。

with the economic development of China, how to adjust the industrial structure and digest the overcapacity has become a heated topic for scholars.As the supply side structural reforms have been put forward, more and more attention has been taken on them.Based on the product space theory, we focus on the dual effect of product features on the industrial upgrade between China and America and test the relationship between RCA and density, as well as the relationship between RCA and product complexity index(PCI) by using the global product trade database to explore the dual effect of product features on the industrial upgrade.The empirical research shows that China have more revealed competitive products with low PCI, which inhibits the development of industrial upgrade.Conversely, the industrial structure of America is of more competitive products with high PCI, which promotes the industrial upgrade in a comparative-advantage-defying way.What's more, the dual effect of product feature varies in different industries in different countries, including the direction and the power of the effect.Further, we analyze the difference of the dual effect of product features in two stages: before the opening and reform and after the opening and reform.There is no doubt that China have more paths to get industrial upgrade with the increasing of production factor endowments and the PCI is bigger.While it’s not enough at all.Because the path of upgrading is comparative-advantage-following strategies, and the low CPI also inhibits the upgrading of the industrial structure.Therefore, China should develop more powerful industries to increase the production factor endowments and the PCI to gain more upgrading abilities in the future.
