近日，對外經濟貿易大學全球價值鏈研究院王直教授、美國哥倫比亞大學商學院魏尚進教授、對外經濟貿易大學國際經濟貿易學院余心玎副教授和中國人民大學經濟學院祝坤福副教授的合作論文“Global value chains over business cycles”在Journal of International Money and Finance正式發表。

Global Value Chains (GVCs) now represent a key aspect of economic interdependence across countries. This paper makes two methodological contributions. First, it proposes a framework with which to decompose total production activities at the country, sector, or country-sector level into different types depending on whether they are for pure domestic demand, traditional international trade, simple GVC activities, and complex GVC activities. Second, this work proposes a set of GVC participation indices that improves on measures used in the literature. Upon applying this framework to Inter-Country Input-Output Tables, we find a number of interesting patterns connecting value chains and business cycles. First, the composition of global production has evolved dramatically since 1995. Second, production activities of complex GVC activities comove with global business cycles more than other types of production activities. Third, the level of GVC participation affects the performance of economic growth.
