Abstract: Based on the literature data from the important journals of system engineering during 2010~2014, this paper adopted two scientometrics measurement indexes including cooperation frequency and Salton cooperation intensity to explore science and technology cooperation of 31 regions in Chinese mainland and describe its spatial structure of science and technology cooperation behavior. Research results showed that different regions were more inclined to regional internal cooperation; geographical proximity had strong regional cooperative tendency; economic or cultural equivalent development level or resource superiority potential difference were easy to promote cooperation. In the study, the Salton cooperation strength index was more realistic to reveal the regional cooperation relationship, and also had the objectivity.
