This session include four presentations on innovation, regeneration and urban in China. The first one focuses on "undefined viaduct space" in Guangzhou. It presents three representative cases with particular attentions on how the state, the street-level administration, the citizens, and the private sectors engage in the production of such sapce. The key observation is that the vacuum of state regulation makes possible of informal subsistence for viaduct bottom space utilization. The second one brings forth several cases of urban regeneration projects in the Pearl River Delta against the new trajectory of innovation replacing the former advance manufacturing and high end services. It interrogates whether the current trend could be fit into a broadened context of gentrification or defined as a new type of urban regeneration model so called innovitization. The third presentation deploys multi-temporal Landsat imagery to investigate urban renewal information. The novelty of the proposed method is identifying urban renewal by detecting redevelopment cycle, which typically involved the change of old-buildings – construction land – new buildings. Compared with built-up areas, construction land is characterized by high spectral reflectance and thus can be easily identified. With 30 Landsat scenes in Guangzhou from 1980 to 2018, urban renewal sites and the start and end time of renewal were both identified. The fourth presentation shift focus to Shanghai, using data of patent applications to map the spatio-temporal evolution of innovation outputs in Shanghai metropolis. Spatial concentration of patent applications in central Shanghai juxtopses that of diffusion in suburban area. Among all the four types of innovation entities, firms contribute most to patent growth and are the main sources of innovation evolution. Though annul Gini Coefficient suggests a high concentrations of innovation activities, the degree of concentration decreased in the past 16 years. The mapping of spots and Gi* contours a changing pathway of how an initial mono-centric innovation space structure evolves to a poly-centric one.
