China is experiencing the unprecedentedly rapid urbanization hence how to build a sustainable city with Chinese featuresbecomes a common challenge for city planners and researchers in the field of sustainability. Beijing has been the imperialcapital of China for more than eight hundred years and is deeply embedded within ancient Chinese urban planning theoriesand thoughts; for this reason it is chosen as the subject of this study. The history of Beijing as an imperial city from theYuan Dynasty to the Qing Dynasty (1267-1912) is reviewed under the framework PEBOSCA, an assessment framework ofsustainable community development which derives from UN HABITAT Agenda. The state of the seven resources ofsustainability is outlined to demonstrate the sustainability of Beijing’s imperial city planning history. Following this,sustainability was assessed at micro- and macro-levels: first the quadrangle as the basic unit of the city is documented andassessed with the Green Building Assessment Standard of China and the LEED for Homes Ranking system in a qualitativeapproach; then the city as a whole was analyzed to assess the interrelationships between the ancient Chinese urban theory –the Fengshui Theory – and urban ecology to understand its implications for the sustainable city planning.The study shows that although sustainable development is becoming a global issue, the key to the challenges faced is local.Integrated with modern technologies, the quadrangle design and the Fengshui Theory will inspire future sustainablecommunity planning and sustainable development.

Over the next decades, China will face various thorny issues caused by the fasturbanization progress. Therefore, Caofeidian eco-city, being the most prominenteco-city project in China, is currently in the course of planning and construction,thereby providing a sound model for future urban development. The master plan of 30square kilometers area and current situation is fully analyzed by the PEBOSCAinterdisciplinary framework based on the UN Habitat agenda. To better realize theeco-city in a Chinese context, a series of interdisciplinary problems and potentialchallenges of Caofeidian eco-city are identified and corresponding interdisciplinarysolutions are presented in this paper. Deferring to the different city developmentstages, a tentative schedule and back casting goals are set to assess the Ecocityperformance in the next 50 years.

Text in German, with summaries in German, English, Afrikaans, and isiZulu / Includes bibliographical references (leaves 111-117) / Das Themengebiet der Wirtschaftsethik bezieht sich auf eine gesellschaftlich höchst relevante Thematik, insofern das Denken in der modernen wirtschaftswissenschaftlichen Disziplin als auch die diesbezüglich tagtäglich im Wirtschaftsleben geübte Praxis teils sehr negative Konsequenzen für Mensch und Umwelt zeitigen. Vor diesem Hintergrund soll in dieser Arbeit das Verhaltensmodells der Standardökonomie, welches den durchschnittlichen wirtschaftlichen Akteur (homo oeconomicus) als rationalen Gewinn- und Nutzenmaximierer beschreibt, in Hinblick auf die zugrunde liegenden normativ-ethischen Grundlagen und den daraus abgeleiteten Umgang mit den beiden zentralen Produktionsfaktoren Arbeit und Kapital untersucht werden. Sodann wird das dahinterstehende Menschenbild und ethische Verhaltensmodell der biblisch-christlichen Anthropologie und Ethik gegenübergestellt und es werden die diesbezüglichen Gemeinsamkeiten und Differenzen herausgearbeitet. In der Beantwortung der Forschungsfrage wird auf ein spezifisch christlich-evangelikales Schrift- und Auslegungsverständnis zurückgegriffen. Die gegenständliche Arbeit zeigt, dass i) das christliche Menschen- und Gottesbild alle Lebensbereiche und somit auch den des Wirtschaftslebens umfasst und ii) sich Gemeinsamkeiten und Differenzen in den Menschenbildern und ethischen Verhaltensmodellen identifizieren lassen. Weiterführende Ansätze werden am Ende skizziert. / The topic of economic ethics refers to a highly relevant societal issue, as the analytical thinking in modern economic science as well as everyday business practice are in part responsible for substantial negative effects on human beings and the environment. Against this background, this research paper describes the behavioural model of standard economics (homo oeconomicus) in terms of the underlying ethical foundations. In the next step, the underlying anthropology and ethics of the homo oeconomicus model are contrasted with the biblical Christian view, and common features as well as fundamental differences are elaborated on. This research paper shows that i) Christian anthropology and ethics refer to all areas of life including the area of economic activity; and ii) common features as well as fundamental differences can be identified. The concluding section outlines some approaches to adapt the standard economic modelling on the basis of biblical principles. / Ekonomiese etiek is ’n hoogs tersaaklike samelewingsvraagstuk omdat analitiese denke in moderne ekonomiese wetenskap én in alledaagse sakepraktyke beduidende gevolge inhou wat ’n negatiewe invloed op mense en die omgewing het. In die lig hiervan beskryf hierdie navorsing die behavioristiese model van standaardekonomie (homo oeconomicus) in terme van die onderliggende etiese grondslag. In die volgende stap word die onderliggende antropologie en etiek van die homo oeconomicus-model en ’n bybelse, christelike standpunt teenoor mekaar gestel. Die kenmerke wat hierdie twee beskouings met mekaar gemeen het sowel as die verskille tussen hulle word in detail uiteengesit. Hierdie studie toon i) dat christelike antropologie en etiek van toepassing is op alle terreine van die lewe, insluitend ekonomiese aktiwiteite; en ii) dat gedeelde kenmerke én grondliggende verskille geïdentifiseer kan word. As deel van die gevolgtrekking word voorgestel hoe die standaard- ekonomiese model aan die hand van bybelse beginsels aangepas kan word. / Isihloko senkambiso elungileyo yezomnotho sibhekiswe odabeni oluphathelene nomphakathi olusemqoka futhi okungudaba olufanelekile kakhulu, njengoba ukucabanga-sakuhlaziya emkhakheni wesayensi yezomnotho wesimanje manje ngokunjalo nezinqubo-nkambiso zansukuzonke eziphathelene nebhizinisi ngandlelathile kunaso isandla kumthelela omubi kakhulu owenzekayo kubantu nakwimvelo. Ngokususela kulesi simo, leli phepha locwaningo lichaza imodeli yokuziphatha eqondiswe emkhakheni wezomnotho ojwayelekile (homo oeconomicus) ngokwezisekelo zenkambiso elungileyo eziqondene nalokhu. Esinyathelweni esilandelayo, isayensi yemvelaphi kanye nenhlalo yabantu (anthropology) kanye nenkambiso elungileyo yemodeli ye-homo oeconomicus eyisisekelo salokhu kuqhathaniswa nombono wobuKrestu wasebhayibhelini, futhi kuchazwa kabanzi ngezinto ezifanayo ezitholakala kulokhu kokubili kanjalo nezicibunjalo ezibalulekile ezenza lokhu kwehluke. Leli phepha locwaningo liyabonisa ukuthi i) imvelaphi nenhlalo yabantu ngokobuKrestu kanye nezinkambiso ezilungileyo zobuKrestu kuqondiswe kuyo yonke imikhakha yempilo kubandakanya nomkhakha wemisebenzi yezomnotho; futhi ii) zingahlonzeka izinto ezifanayo kanye nezinto ezibalulekile ezihlukile kulokhu okubili. Isigaba sokuphothula sibeka ngokucacile izindlela ezithile zokuhambelanisa amamodeli ezomnotho ajwayelekile nemigomo yebhayibheli. / Philosophy, Practical and Systematic Theology / M. Th.
