Abstract: Selecting the data of 2012—2016 in the Yangtze River Delta region, the coupling coordination degree model and influencing factor model between regional innovation and informatization are constructed. The principal component analysis method is used to determine the index weight, the comprehensive evaluation index of the Yangtze River Delta region is calculated according to the coupling coordination degree model, while its influencing factors are analyzed by means of fixed effect regression. The results show that the coupling and coordination of innovation and informatization between cities in the Yangtze River Delta region are very different, and the overall high quality coupling and coordination haven't been achieved. The innovation level of the core cities in this region lags behind the informationization level, while of the small and medium-sized cities are opposite. The level of input and the level of urbanization promote the coordinated development of innovation and informatization significantly, while effect of the level of education and openness are not obvious. Based on this, the region should increase innovation support, continue to improve the level of urbanization, and take the balanced development between regions into account.

Key words: Yangtze River Delta, regional innovation, regional informatization, coupling coordination analysis
