　　摘要：In recent years, smart city is hot. We remember, however, numerous urban concepts had emerged and disappeared. Eco city, creative city, world city, and global city are only a few of those. Geographers, planners, architects and other urbanists debate to improve the concept and whether the concept explain urban changes. However, it was rarely asked why there are so many urban concepts in the first place. This paper offer an explanation on frequent changes in urban discourse from Marxian economic perspective. In Marxist tradition, built environment is considered as means of production like machine. However, it was not discussed how built environment is different from machine as means of production. I argue in this paper, that the long duration of capital circulation and agglomeration economy are the two main difference of built environment from machine. I further argue that these two unique characteristics of built environment shackles capital circulation in built environment sector and urban discourses are used to partly overcome such problem. 

　　主讲人介绍：Dr. Sonn's research is focused on two themes in urban and regional economic development: (1) the urban and regional dimension of technological knowledge production and (2) political analysis of regional economic planning. The geographical focuses of his research are the U.S., South Korea and China. Funded projects include temporal changes of localised knowledge spillovers in the U.S. (North American Association of Regional Science), the emergence of a metropolitan knowledge cluster (the Leverhulme Trust), a comparative study of innovative capacities between the Seoul metropolitan area and the Southeast region (the Asian Institute for Regional Innovation), creative centres as a new orthodoxy in Chinese urban development (the Royal Institution of Chartered Surveyors) and Localised knowledge spillovers and regional absorptive capacity (European Commission).
