Abstract: With the development of social productivity and the increasing complexity of engineering technology， the connotation of craftsman spirit has been continuously enriched and developed. The longer the history， the richer its meaning. Since the reform and opening-up， China has made brilliant achievements in the four fields of science， technology， engineering and industry in the world competition. In particular， it has been able to stand out in the field of engineering construction， thanks in large part to the craftsmanship of Chinese engineers. This kind of craftsman spirit has developed into a new era， and has already got rid of the limitations of micro-individual ingenuity and has risen to the spirit of Chinese craftsmanship in the new era in the macro-collective sense. Based on the spirit of Chinese traditional craftsmen and guided by the world outlook and methodology of dialectical materialism， it is of theoretical and practical significance to explore the connotation and philosophical foundation of the Chinese craftsman spirit in the new era， and carry the spirit on and forward in the great project of socialist modernization with Chinese characteristics.

Key words: craftsman spirit, craftsman spirit with Chinese characteristics, dialectical materialism, historical materialism
