The Coupling Relationship Between Industrial Linkage and Spatial Co-agglomeration of Advanced Manufacturing and Producer Services in Metropolitan: A Case Study of Beijing, China

Promoting the deep integration of advanced manufacturing and producer services is not only a key path for metropolitan to climb the global value chain, but also an important new driving force for optimizing urban spatial structure. Based on the two dimensions of industrial linkage and spatial co-agglomeration from the perspective of industrial integration, taking Beijing, China as a case, using industrial input-output data, micro-enterprise spatial data, and methods such as industrial linkage model, standard deviation ellipse, and spatial similarity coefficient, this study explores the coupling relationship between industrial linkage and spatial co-agglomeration of advanced manufacturing and producer services from 2007 to 2020. The results demonstrate that: 1) the industrial linkage between advanced manufacturing and producer services in Beijing has an upward trend, in which the business services have the most significant improvement, in which the business services have the most improvement while the technology services have the most decrease, but in general, the industrial linkage between the two industries shows a low level. 2) Producer services were more spatially clustered than advanced manufacturing, and the degree of spatial co-agglomeration of the two also showed an increasing trend, with strong regional and industrial heterogeneity characteristics, among which the pairing industry involving commerce services and technology services had a more obvious improvement. 3) The coupling analysis found that the spatial dependence between advanced manufacturing and producer services decreased, showing a weak positive correlation and a decreasing trend between industrial linkage and spatial co-agglomeration; the heterogeneity among subdivision pairs is prominent, and the strong correlation between industries does not mean that there is an inevitable spatial co-agglomeration. 4) Based on the differences in coupling relationships and influence mechanisms, four coupling modes are identified: H-H type, H-L type, L-L type, and L-H type. Finally, this study proposes three policy implications for the integration of advanced manufacturing and producer services in metropolitan areas.
