英文摘要：

As the Belt and Road construction needs the support of scientific and systemic theories of Eco- nomics and the present theories and academic research can not satisfy this need, it is necessary to establish the Belt and Road Economics. The academic research at home and abroad, the important argumentation of President Xi Jinping and leaders of other countries, plus the policies and documents of joint construction of China and foreign countries have laid the theoretical foundation for its establishment. The research object is the new relationship of international division of work and cooperation between the Belt and Road countries formed during the Belt and Road construction. The research focuses on the coordinated development based on connectivity between the Belt and Road countries. The main research framework includes the back- ground, coordinated development, connectivity, risk prevention and supporting system for the Belt and Road construction.
