Since the unification of Germany, Germany has been making great efforts to improve the urban environment in the East Germany. Among the many policies implemented in the East Germany, the Urban architecture promotion(Städtebauförderung) plays a major role. The purpose of this study is to analyze the meaning of urban regeneration of the Urban architecture promotion(Städtebauförderung) based on the analysis of changes in the East Germany after the implementation of the Urban architecture promotion(Städtebauförderung). The Urban architecture promotion(Städtebauförderung) started in the West Germany in 1971, and its purpose and method have been maintained even after the unification of Germany. At the beginning of the implementation of the urban architecture promotion(Städtebauförderung) in West Germany, the Urban Architectural Maintenance and Development Measures(Städtebauliche Sanierungs- und Entwickungsnaßnahme) program was implemented, and after the unification of Germany, the Urban Architectural Cultural Heritage Protection(Städtebaulicher Denkmalschutz) Program was first implemented. Currently, programs such as the Social cities(Soziale Stadt), the Urban redevelopment in East Germany(Stadtumbau Ost), the Active urban and regional centers(Aktive Stadt- und Ortsteilzentren), the Small cities and villages(Kleinere Städte und Gemeinden), and the Future urban greens(Zukunft Stadtgrün) are being implemented. Each of these programs of the Urban architecture promotion(Städtebauförderung) is selected and applied according to the regional situation, and the negative factors of the city are removed for the purpose of balanced urban development, thereby resolving the imbalance between cities through the improvement of the urban environment. The Urban architecture promotion(Städtebauförderung) is not an improvement of the city's physical environment through redevelopment and reconstruction, but a method of improving the urban environment through improvement of the underdeveloped or problematic areas that maintain the urban context. Therefore, the urban architecture promotion(Städtebauförderung) has a sustainable urban environment improvement method in terms of content. In this sense, urban architecture promotion(Städtebauförderung) is not a simple method of improving the urban environment, but has the meaning of sustainable urban regeneration.
