Hongqiao Hub in Shanghai

In China, urban development goes hand in hand with the development of the rail network. Across the country, large regional plans are being drawn up, referring to the principles of globalization and global cities. The establishment of High Speed Railway (HSR) is one example, it is located on the outskirts of the cities and develops an urban form adjacent to the station. This master thesis proposes to analyze this new urban form around the establishment of stations by questioning its "integration" on several scales to understand the issues. The Hongqiao Hub in Shanghai is the main case study, it is examined on several scales reflecting the different integration strategies and their consequence on three different scales. Hongqiao Hub is an exceptional form in the establishment of HSR type stations by its hybrid form by integrating an airport in the same building group. The first scale provides answers on the Mega-Region system favored by the passenger rail network. It allows increased competition between cities, confirming Shanghai’s position as the main city of the Yangtze region. At the scale of the Municipality of Shanghai, it supports the principle of polycentric integration of the city, linking the southwestern part of Shanghai linking with the secondary centers. It highlights a strategy of centrality of the business district established by economic tools and preferential tariffs orchestrated by actors of the public-private partnership. The last scale examines the whole district with field work that informs the transition from the station to the surrounding neighborhood on the one hand, and on the other hand studies the urban life which is catalyzed in the whole district by 6 samples of one kilometer square. The integration is reflected in a typological cluster consisting of the shopping center, the business district and the "gated communities". It confirms the predominance of flows throughout the district, reflecting a sectored urban form for efficient flows, and shows a tendency to reduce urban life in the semi-private to private sector.
