Due to historical condition reason, the pace of art design development in China is late. Since the reform and opening up, the art design obtains a long-term development in China. In order to adapt to the trend of world economy integration, all aspects of art design fields in China are learning from the foreign countries, however, it is hard to have a breakthrough creation in itself, and it lacks of domestic art design ＂localization＂ , which can not fully reflect the national culture and national elements. At the same time, the self-innovation power is weak, and the creation ability is insufficient, which also restricts the independent development of art design field to a higher level in China. The art design, as a comprehensive subject, is affected by many factors of society, science and technology and market for its own improvement. This paper mainly discusses from national culture level for art design, thinking that if the art design in China wants to develop higher, it needs to be based on the national culture and profound cultural base, constructing the art design products with Chinese national styles.展开更多

文摘The progress of social economy drives the progress of humanity art. Due to historical condition reason, the pace of art design development in China is late. Since the reform and opening up, the art design obtains a long-term development in China. In order to adapt to the trend of world economy integration, all aspects of art design fields in China are learning from the foreign countries, however, it is hard to have a breakthrough creation in itself, and it lacks of domestic art design ＂localization＂ , which can not fully reflect the national culture and national elements. At the same time, the self-innovation power is weak, and the creation ability is insufficient, which also restricts the independent development of art design field to a higher level in China. The art design, as a comprehensive subject, is affected by many factors of society, science and technology and market for its own improvement. This paper mainly discusses from national culture level for art design, thinking that if the art design in China wants to develop higher, it needs to be based on the national culture and profound cultural base, constructing the art design products with Chinese national styles.
