  Recent years have witnessed an exceptional extension of public transportation
networks in People's Republic of China, both at a national scale with the
construction of the first HSR railway network of the world, and at local scales
with numerous cities developing high coverage subway networks often from
scratch. This chapter studies these mutations, both from a quantitative
perspective with the study of the evolution of population accessibility
landscapes, at a national level and for several cities, and from a qualitative
perspective with fieldwork observations. We confirm that rebalancing planning
objectives are well achieved in terms of accessibility at both scales, when all
planned lines will be achieved but already in a significant manner. We finally
hypothesize possible paths for the coupled network-territory systems, given the
extent without precedent of such mutations.
