Based on the perspective of innovation process and the integration of attention-based view and resource-based view, this study analyzes the impact of the difference between the marketing ability of high-tech companies on the stage of innovation of decision-making and the stage of achievement transformation. First of all, marketing ability may affect the attention of the company and thus affect the decision of innovation input. Secondly, marketing ability will affect the commercialization efficiency of the company's product innovation, thus affecting the relationship between innovation investment and performance. Taking A-share listed high-tech companies from 2012 to 2017 as samples, this paper empirically tests all theoretical hypotheses. The results show that in the stage of innovation of decision-making, marketing ability has a significant inhibitory effect and "crowding out" effect on innovation input. In the stage of achievement transformation, marketing ability promotes the positive influence of innovation input on corporate performance, and innovation input in the early stage has significant positive influence on innovation input in the current stage. The research in this paper expands the theoretical framework of how marketing ability influences corporate innovation in the past, enriches the research on the dynamic changes of innovation input and corporate performance, and has practical guidance and inspiration for understanding the allocation of marketing and innovation resource of high-tech manufacturing enterprises in China.
