THE INTENSIVE EXCHANGES FLOWS About a "New Regionalism": OBOR ("One Belt, One Road")

Regionalism agreements are susceptible to create a traffic diversion. Since the beginning of the millennium, multilateralism stalled (cycle Doha down); where so-called regional's policies are impulse whether from United States (TPP, TTIP) or China (OBOR: New Silk Road launched in 2013). These attempts agreements take place in the areas traversed by intensive exchanges flows, tangible and intangible. Knowledge, Innovation and Trade reinforce each other by intensity. The "intensive exchanges flows" are a transformation of macroeconomics solidarities. Since 1986, a global business cycle is based on a more or less highly dynamic of exchanges: rather an informal regionalism of major trade roads. Exchange and Knowledge are joined, but with non- linearity: spillovers of knowledge are bigger if exchanges are more than average.
