Introduction: Urban morphology can be defined as the study of spatial and physical characteristics of towns and cities as a result of spontaneous and purposeful building practices.Though typological thinking is an available way to study how the area changed over time, it was discussed among Chinese architects as late as the 1980s, since then an interest has developed in relevance to architectural design, urban conservation, and analysis of historical building forms, but it hadn’t been applied in industrial districts. Now “transformation of old industrial area” becomes a heat issue in China. Hitherto studies about it concentrate on transform patterns and problems, little about its whole revolution process. In China,Urban planning is made for ten or more years with certain predictions. However development process of a specific area is dynamic, concerning many aspects, so outcomes may contrast to the government’s intentions. Industrial districts are particularly important in this regard because of weak policy and powerful economic processes–the particular case of Bagualing industrial district in Shenzhen. The original plan proposed Bagualing as an industrial area, but now it is becoming a comprehensive area. This research want to discuss: How this area changed over time?To what extent does the morphology support the transformation? What is the role of the government and leaseholders during this process? What interventions are possible in this bottom-up transformation process? How can the top-down planning by government be adjusted to meet with the reality of spontaneous transformation?

The research methods in this study are documentation and field work. Documents derive from the Government website. Basic map download from Google earth. Seven members divided into 4 groups. And whole area was divided into three parts, one group investigate one part.We interview two kinds of people: 1-work or living in Bagualing(at least ten person was interviewed in each building if the change is obvious);2-people working in the property management company(5 persons was interviewed) . The main questions are: when this building constructed? Who is the owner? When it changed the function (if had)? Where first to change? why it changed ?What‘s the policies for transformation? How much is the present rent?

The government's policies,market needs and urban planning have a big influence on the morphological evolution of this area.It can be divided into three developing stages.During the past 30 years, the street layout has not changed but subway has appeared in 2013 year. Individual streets have their own morphological characteristics, with Baguayijie the special focus of this presentation. Buildings' change by two ways: 1-redecoration and reuse;2-demolition and rebuilding. The first floor of nearly all buildings, especially those along the main street, has redecorated for commerce. The property relationships are complex,which make it hard for the government to change comprehensively with large-scale interventions, so they allow spontaneous change by extending the land use right for twenty years. Now Industry also occupies a large proportion but appearing industrial clusters in spatial distribution.

This research performs a new morphological analysis to study the evolution of industrial area .It exams the use of morphological theory in a specific area and provides an object and rational viewpoint to understand the evolution of industrial area except perceptual description.
