Global technological collaboration network: network analysis of international co-inventions

  • Giuditta De Prato
  • Daniel Nepelski


Global innovation networks are emerging as a result of the international division of innovation processes through, among others, international technological collaborations. At the aggregate level, the creation of technological collaboration between countries can be considered as mutually beneficial (or detrimental) and their random distribution is unlikely. Consequently, the dynamics and evolution of the technological collaborations can be expected to fulfil the criteria of a complex network. To study the structure and evolution of the global technological collaboration network, we use patent-based data of international co-inventions and apply the network analysis. In addition, extending the gravity model of international technological collaboration by network measures, we show that a country’s position in the network has very strong impact on the intensity of collaboration with other countries.
