| Abstract |
The R&D of urban greening technology is an important impetus for the realization of ecological city and green city. The patent literatures as records of scientific inventions, have recorded a large number of technical information which is true, accurate and informative. Through statistical analysis of the patent information, we can obtain the competitive intelligence of technological innovation's processes and new developments. In this paper, based on the urban greening technology public patents in the China Patent Database of 1985-2012, we can obtain the urban greening patent intensive distribution fields through the IPC analysis, and then analyze the detailed patents in these fields, dig out the R&D hotspots which scientific research personnel concerned, provide references for the development of urban greening technology, promote the R&D of new intellectual achievements. |
