For the impact of integration of informationization and industrialization on corporate innovation,exiting literature ignores two important issues: firstly,corporate activities are connected by the convergence of value chains,and information technology or products will penetrate into different value chain links; secondly,corporate innovation activities are featured by diversification,and innovation forms are different in different value chain links.Hence,based on the questionnaire of Chinese firms in the World Bank Business Environment and Enterprise Performance Survey in 2012,this paper empirically tests the effect of integration of informationization and industrialization on corporate innovation from the perspective of enterprise value chains.It arrives at the following conclusions that the integration of product design,marketing and informationization improves the tendency of product innovation input and the integration of manufacturing link and informationization advances the tendency of process innovation input.Furthermore,it shows that the increase in the whole level of integration of informationization and industrialization can increase output value of corporate new products and helps to realize corporate economic benefits.It not only enriches the understanding of the impact of integration of informationization and industrialization on corporate innovation,but also has important implications for the promotion of innovation capacity in manufacturing and the transformation of economic structure.
