Abstract: Haidian science and Technology Park is the national innovation center of high-tech industry. The central government pursues to construct it as the national demonstration zone of transforming technological innovation resources into innovation ability. In this paper we explore and compare the innovation process of manufacturing and information service industry based on the firm-level data of Haidian Science Park by using the model proposed by Crépon, Duguet and Mairesse (CDM). We expect to find the common and different stories of the innovation process between manufacturing and information service industry. We find that in information service industry the relationship between firm size and the propensity of producing new product is inverted U shape, while in manufacturing the larger the firm is the higher the propensity of producing new product. Information service industry is knowledge-intensive while we didn’t find the same result in manufacturing. Although in information service industry state-owned firms have similar innovation input intensity as other types of ownership firms, their innovative conversion efficiency is lowest, which means they have lower innovation efficiency. In Manufacturing state-owned firms lack motivation to carry out innovation in the first stage.
