Abstract: The implementation of the Yangtze River Economic Belt strategy has important significance for promoting the economic development of our country, and the Yangtze River Economic Belt innovation ability to promote the development is the key factor. Based on the quantitative research methods of standard deviation index, variation coefficient, location Gini coefficient and concentration index, the regional innovation differences of the Yangtze River Economic Belt in the urban agglomeration level, provincial and municipal level and its reasons were studied. The research showed that the regional innovation had a sustained growth trend, and the regional innovation difference increased with the increase of the regional scale. The main causes of different regional scales affecting the innovation of the Yangtze River economic belt were different. The social environment factor was the main factor that affected the innovation of urban agglomeration. The economic environment was the main factor affecting the innovation of the province. Urban innovation was the main external factors affecting the differences. Innovation concentration decreased with the increase of regional scale. The middle reaches of the Yangtze River and the Chengdu-Chongqing city groups were in the stage of innovation activities toward to the center of the city agglomeration. However, the Yangtze River Delta city group began to enter the diffusion stage of innovation activities, and the Yangtze River Delta city group would form a huge innovation cluster system.

Key words: Yangtze River economic belt, innovation difference, regional scale, innovation cluster
