Abstract:With the further advance of "the Belt and Road" strategy, international economic and technological cooperation among China and "the Belt and Road" countries is becoming further and further strengthened. Our survey is based on technology areas analysis of "the Belt and Road” countries’ patent application in China along 12th Five-Year Plan. Dividing all these countries into six zones, we make analysis of temporal and spatial trends, and add in-depth analysis of the technology areas on this basis, and finally find the technology areas of great advantage, and further we can find the "the Belt and Road" countries country's technical characteristics and trends of the patent layout; while the top five countries to apply for patents in China are analyzed, and according to correspondence WIPO published between patent IPC Classification and technical fields, we match the technical area of "the Belt and Road” countries’ patent application in China with the country's commercial type to provide decision-making reference for the further implementation of the " the Belt and Road " strategy .
