Research on measuring and assessing the development of nanotechnology based on co-countries and co-institutions analysis

This paper chooses the SCI (Science Citation Index) data co-published by Chinese author from 1985 to 2011 to research the international technology cooperation of P. R. China resent years. In this paper, we are focused on three main collaboration countries (USA, Japan and Germany).We combine bibliometric analysis and social network analysis method to analyze and compare collaboration between USA, Japan, Germany and China based on the analysis of co-countries, co-institutions together. In addition, we adopted the scientometric analysis and social network method to make further and deeper exploration and analysis of China's international technology collaboration situation. We find that most of the co-countries are from some developed ones, such the United States, Taiwan province, Hong Kong and Japan and the international cooperation between the institutions is not close, just focused on the several American institutions. In addition, the research fields are room term, carbon, magnetic, electron, transmit in nanotechnology.
