It also analyzes the economic development characteristics, regional patterns, and location distributions of Mianyang, Deyang, Leshan, Yibin, Luzhou, Nanchong and Dazhou, the seven alternative subcenters in Sichuan province. It focuses on the analysis of their basic situations regarding scientific and technological(S&T) innovation development including investment in S&T innovation, talent team construction, S&T achievements, industrial structure and S&T platforms compared with the innovative subcenters in leading provinces. Results show that the scale of S&T innovation activities in the seven alternative subcenters in Sichuan province needs to be improved. Finally, based on the ChengduChongqing economic circle strategy, this paper puts forward the thoughts and suggestions on how to cultivate the innovative subcenters in Sichuan province.展开更多
