Major Research Plan
Aims

• strengthen basic and applied researches in key
  areas
• enhance the nation's sustainable creative
  capability in science and technology

Major Research Plan will meet the regularity and
characteristics of basic research, aim at key
scientific issues, and integrate and assemble the
projects with different disciplinary backgrounds,
various academic thinking and at different levels
(including General, Key and Major projects) so as
to form a group of projects with an integrated
objective. Major Research Plan will receive
relatively longer funding (6-8 years) for the
sake of promoting interdisciplinary research and
academic content and stimulating
creativity. ---http//www.nsfc.gov.cn
