The Evolution of Trade and Scientific Collaboration Networks in the Global Wine Sector: A Longitudinal Study Using Network Analysis

Abstract

Throughout the past three decades, the global pattern of wine production has undergone fundamental changes, most notably the emergence of New World producers. This article presents a detailed account of the sector’s changing global organization from 1974 to 2004 by applying network analysis methods to the evolution of international trade and scientific collaboration networks. We argue that there is a strong mutual interdependence of trade and scientific knowledge production, as a result of which we expect the geographic configuration of global knowledge and trade networks to coevolve. Our results show that, over time, only a few New World wine producers developed trade and scientific collaboration networks that resemble those of traditional Old World producers. They also show that structures of trade and scientific collaboration networks are more alike for Old World than for New World producers, which suggests that, contrary to our expectations, it is particularly Old World producers who may have mainly benefited from participation in international scientific collaboration.
