The Regional Innovation System in China: Regional comparison of technology, venture financing, and human capital focusing on Shenzhen

Shenzhen has become a hot spot of innovation in China. In this paper, we characterize Shenzhen's innovation by comparing it with that of Beijing and Shanghai using patent and venture investment data. First, the role of universities and public research institutions is small in Shenzhen's innovation system as compared to Beijing and Shanghai. In contrast, private high-tech firms, such as Huawei, ZTE, and Tencent, are leading the innovation scene in Shenzhen. Second, we find that high-tech start-ups are geographically concentrated in the Nanshan district, particularly Yuehai Jiedao, where national-level high-tech zones are located. Recently, the number of start-ups has been increasing, and local, big firms, such as ZTE, are providing the human resources for such start-up firms. Third, inventor-disambiguated information based on patent data allows us to look at interorganizational talent movements. We find that such movements tend to occur within short distances, such as within the same district (e.g., Nanshan district). To sum up, Shenzhen has truly become a hot spot of high-tech entrepreneurship and innovation, but the dynamics are very much regionally bound. Therefore, it is important to become a local player in order to take advantage of innovation movements in Shenzhen by means of minority investment by corporate venture capital into local start-up firms.
