Development and Evolution of Collective Welfare Facilities in Industrial Living Areas of Old Industrial Cities：Taking Three Samples in Xianyang as an Example

Collective welfare facilities are a product of the industrial construction period， not only reflecting the collectivist ideology under specific historical conditions， but also witnessing the development and evolution of industrial construction，production and lifestyle. The study takes Xianyang City in Shaanxi Province as an example. Based on the industrial living area welfare facilities in the era of enterprise-run society in China， the study takes the collective welfare facilities of Northwest State Cotton Factory No.2（Factory No.2）， Northwest State Cotton Factory No.7（Factory No.7）， and Shaanxi Colour Picture Tube Plant（CPT Plant）， which were constructed in different historical periods， as samples and examines them through the analysis. The study systematically sorted out the planning， layout ideas and spatial characteristics of the collective welfare facilities in the living areas during the early period of the planned economy， the period of the Great Leap Forward， and the early period of reform and opening-up， after which it reveals the evolution process from closed self-use to open public use. The study provides a historical basis for further enriching the value study of industrial heritage in China， and also provides a historical basis for the protection and reuse of architectural heritage in high-quality urban renewal.
