Abstract: Abstract：Based on the industrial innovation index, the spatial econometric model is used to analyze the spatial and temporal evolution pattern and spillover effect of the innovation capability development of strategic emerging industries in the Yangtze river economic belt from 2001 to 2016. The research finds that :(1) the innovation capacity of strategic emerging industries in the Yangtze river economic belt increases rapidly on the whole, but the spatial difference is expanding on the whole. The spatial non-equilibrium of innovation capability is remarkable, and the “east is strong and west is weak” zonal pattern is stable. (2) the innovation capacity of strategic emerging industries in the Yangtze river economic belt is significantly positively correlated in space. Hot spots in the Yangtze river delta region are stable, while cold spots are increasing. (3) strategic emerging industries each subdivision industry innovation ability development state is differ, high-end equipment manufacturing industry, new material industry, new energy automobile industry are the core shaft schema evolution, a new generation of information technology industry is single center polarization mode evolution, energy conservation and environmental protection industry, biological industry, new energy industry is the core group schema evolution; (4) spatial spillover effect exists in innovation capacity of strategic emerging industries. In addition to human resources, economic development level, industrial structure, government policy, external contact level and innovation environment produce obvious positive effects.
