  3. Context of Study The introduction of the ‘National New-type Urbanisation Plan’ by the Chinese government in March 2014 signifies a shift in its urban development strategy towards a more human-centred and environmentally sustainable pathway. The ‘New-type Urbanization Plan’ will result in the construction of 30 million units of housing, with associated public amenities and infrastructure, over the next seven years. As the urban form and associated infrastructure are not locked in yet, this rapid development presents challenges and opportunities to move towards a new type of urbanisation that is financially and environmentally sustainable.
  4. Context of Study In order to accommodate the rapid increase in urbanisation, the concept of a ‘new’ type of urbanisation is introduced for: • Coordinating urban and rural development; • Supporting an urban lifestyle for ecological production and consumption; • Making basic urban public services available to all permanent urban residents; • Optimizing macro-level city layouts; • Integrating ‘ecological civilization’ into the urbanization process.
  5. Context of Study • There are however inherent tensions among these core principles as increasing service provision, housing and infrastructure development will increase the built-up area and urban land cover and could have major implications on future energy use and emissions; • The 2014 IPCC (p.940) report argues that the income gap in China between urban and rural areas has caused major differences in consumption and that there is a positive relationship between economic growth and CO2 emissions of urban areas in China.
  6. Context of Study • Rapid urbanization of China is exerting environmental impact • Impact aggregated on population health and human well- being in cities particularly in poor communities • China has strict environmental codes and standards however these are often not adhered to, and they have sometimes been placed second to economic goals • Whether the efficiency gains from urbanisation can offset the scale of environmental challenges brought by the associated growth consumption and infrastructure construction?
  7. Context of Study • Chinese cities, like cities across the globe face challenges of resource use, green space, species conservation, biodiversity, pollution, security, public service provision, population growth and adapting to climate change. • There is an opportunity for Chinese policymakers to learn from the experiments and best practices of other urban areas in developing effective strategies to enhance the urban environments and sustainability in future.
  8. Relevant definitions • Urban ecosystem:a complex artificial-socio-economic-ecosystem. • Ecological communities: the modern ecological communities which with the human and the nature harmonious as the core and can play an ecological function. • Integrated urban eco-communities management from multidimensional and interdisciplinary research on:planning, industrial structure, resource utilization and allocation policy, eco-environmental protection, for urban adaptation and ecosystem sustainability. The kernel is the relationships between human well-being and eco-environmental sustainability which drives and be interacted by economic production, conscience of life cycling, and environmental conservation for green development.
  9. Context of Study l Avoid vicious cycle of urbanization in future China; l Predict resource utilization and environmental capacity; l Implicate co-design of urban transformation and eco-environmental adaptation. New-type urbanization l Balance between high speed of economic growth and resource consumption; l Coordination on the trade-offs and synergies of multiple benefits between current and future generation. Eco-civilization

  11. Key research questions • What kind of eco-environment can grantee a better living standard of urban residents? How to quantitatively assess the impacts from their changing consumption patterns? • Where an integrated management options can be formulated and concentrated for efficiently and effectively allocating resources and improving using their using efficiency as well ? • How policy interventions can be enforced to coordinating conflicts between resource supply and demand in urban or potential urban area? How could we enhance our actions in a clear order?
  12. Conceptual framework - explore spatial distribution - analyze driving indicators or impact factors -integrated modelling - management and policy implication in hierarchical frameworks
  13. Key research issues 1. Eco-community construction constrained by supply and demand of resources o Eco-environmental indicators assessment o Comprehensive life cycle assessment 2. Urban management for decision making o Urban resource and ecosystem assessment o Eco-asset valuation and assessment 3. Eco-efficiency and environmental effects o Data Envelopment Analysis on eco-environmental effects o Modelling eco-efficiency of environmental effects 4. Urban adaptation and policy implication o Stochastic frontier approach for eco-environmental management o Integrated modelling of urban eco-environmental optimization process for ecologically adaptive management strategies
  14. 1. Eco-community construction given resource supply and demand • An overview of the evolving contexts of urban development in terms of the interactions among the economic, socio-cultural, and environmental aspects, and the changing institutional and legal frameworks that have evolved in response to the challenges brought by globalization, climate change and rapid urbanization. • A meta-analysis of the literature review will be produced; and the conceptual framework will be refined by adapting relevant theories and methods to the rapid development context of China to examine the relationship between urban development, lifestyles, resource consumption, and environmental impacts and to identify the key characteristics of a ‘well-being’ oriented urban future. Eco-environmental indicators assessment
  15. 1. Eco-community construction given resource supply and demand Life cycle assessment Analysis of lifestyle and consumption patterns in typical eco-cities and their impacts on the urban and regional environment by conducting integrated life cycle assessment.
  16. 2. Urban management for decision making Urban resource and ecosystem assessment In-depth quantitative study on the efficiency of urban ecology, environment, and resource utilisation for sustainable development and the selected local communities to identify key impact factors of environmental changes brought by regional economic development and urbanisation.
  17. 2. Urban management for decision making Eco-asset valuation and assessment Identifying formal legislation and regulations, financial and other incentives, investment and strategies in relation to economic growth, service and infrastructure provisions and environmental management in Chinese cities.
  18. 3. Eco-efficiency and environmental effects Data Envelopment Analysis on eco- environmental effects Evaluate the comprehensive efficiency of ecological community by conducting a data envelopment analysis.
  19. 3. Eco-efficiency and environmental effects Modelling eco-efficiency of environmental effects • Based on the literature review and field research, the research parameters such as urban size, spatial scale, study period, etc. will be chosen to finalize the data collection methodologies and analytical framework of the trend patterns of eco-management. • Undertaking a compilation of secondary statistics to construct sector-based indices and performing an analysis (e.g. shift-share analysis to ascertain the relationship between innovation-economic-environmental performance to contextualize and benchmark the state of sustainable development) that can be used in the integrated model. • Analysis of lifestyle and consumption patterns in typical eco-cities and their impacts on the urban and regional environment by using methods such as index decomposition method and DEA.
  20. 4. Urban adaptation and policy implication Stochastic frontier approach for eco-environmental management Applying SFA to calculate eco-efficiency and to assess the ecological adaption management patterns to figure out a series of adaptive and feasible measurement strategies. The findings can then inform the development of eco-city policy and urban land use planning to meet the objectives of sustainable urbanization.

Urban adaptation and policy implication Integrated modelling of urban eco- environmental optimization process for updating managerial strategies Synthesizing the findings to provide insights to inform the design of institutional frameworks, governance structures, and policy and monitoring measures on the planning and management of ecological environmental performance of rapid urban growth, including beyond the Chinese context.
