十七大以来,中国共产党在深刻总结领导全国各族人民推动科学发展、促进社会和谐的实践经验,尤其是在办成大事、办好喜事、办妥难事的基础上丰富和发展了科学发展观。本文从以人为本的执政理念、加快转变经济发展方式、把社会建设摆在更加突出的地位和以改革创新精神加强党的建设这四个主要方面作了梳理和总结,并且认为研究党的十七大以来科学发展观的新发展,具有重要的理论意义和政治意义。 Since the 17th CPC National Congress, the CPC has profoundly summed up the practical experience of leading the people of all ethnic groups across the country in promoting scientific development and promoting social harmony, and especially enriched and developed the scientific concept of development based on the accomplishment of major events, the promotion of happy events and the fulfillment of difficult tasks . In this paper, we review and summarize the four major aspects of people-oriented ruling philosophy, speeding up the transformation of economic development mode, placing social construction in a more prominent position and strengthening party building with the spirit of reform and innovation, and think that the study of the 17th CPC National Congress Since the new development of scientific concept of development, has an important theoretical and political significance.
