industrial symbiosis is the quintessential characteristic of an eco-industrial park. To divide parks into different types, previous studies mostly focused on qualitative judgments, and failed to use metrics to conduct quantitative research on the intemal structural or functional characteristics of a park. To analyze a park＇s structural attributes, a range of metrics from network analysis have been applied, but few researchers have compared two or more symbioses using multiple metrics. In this study, we used two metrics （density and network degree centraliza- tion） to compare the degrees of completeness and dependence of eight diverse but representative industrial symbiosis networks. Through the combination of the two metrics, we divided the networks into three types： weak completeness, and two forms of strong completeness, namely ＂anchor tenant＂ mutualism and ＂equality-oriented＂ mutualism. The results showed that the networks with a weak degree of completeness were sparse and had few connections among nodes; for ＂anchor tenant＂ mutualism, the degree of completeness was relatively high, but the affiliated members were too dependent on core members; and the members in ＂equality-oriented＂ mutualism had equal roles, with diverse and flexible symbiotic paths. These results revealed some of the systems＇ internal structure and how different structures influenced the exchanges of materials, energy, and knowledge among members of a system, thereby providing insights into threats that may destabilize the network. Based on this analysis, we provide examples of the advantages and effectiveness of recent improvement projects in a typical Chinese eco-industrial park （Shandong Lubei）.

A review of industrial symbiosis research： theory and methodology

引用

Frontiers of Earth Science 2015年第1期9卷 91-104页

作者： Yan ZHANG Hongmei ZHENG Bin CHEN Meirong SU Gengyuan LIU State Key Joint Laboratory of Environment Simulation and Pollution Control School of Environment Beijing Normal University Beijing 100875 China

The theory, methodologies, and case studies in the field of industrial symbiosis have been developing for nearly 30 years. In this paper, we trace the development history of industrial symbiosis, and review its current theoretical and methodological bases, as well as trends in current research. Based on the research gaps that we identify, we provide suggestions to guide the future development of this approach to permit more comprehensive analyses. Our theoretical review includes key definitions, a classification system, and a description of the formation and development mechanisms. We discuss methodological studies from the perspective of individual industrial metabolic processes and network analysis. Analyzing specific metabolic processes can help to characterize the exchanges of materials and energy, and to reveal the ecological performance and economic benefits of the symbiosis. Network analysis methods are increasingly being used to analyze both the structural and functional characteristics of a system. Our suggestions for future research focus on three aspects： how to quantitatively classify industrial symbiosis systems, monitor the dynamics of a developing industrial symbiosis system, and analyze its internal attributes more deeply.

Social network analysis and network connectedness analysis for industrial symbiotic systems： model development and case study

Frontiers of Earth Science 2013年第2期7卷 169-181页

作者： Yan ZHANG Hongmei ZHENG Bin CHEN Naijin YANG State Key Joint Laboratory of Environment Simulation and Pollution Control School of Environment Beijing Normal University Beijing 100875 China

An important and practical pattern of industrial symbiosis is rapidly developing： eco-industrial parks. In this study, we used social network analysis to study the network connectedness （i.e., the proportion of the theoretical number of connections that had been achieved） and related attributes of these hybrid ecological and industrial symbiotic systems. This approach provided insights into details of the network＇s interior and analyzed the overall degree of connectedness and the relationships among the nodes within the network. We then characterized the structural attributes of the network and subnetwork nodes at two levels （core and periphery）, thereby providing insights into the operational problems within each eco-industrial park. We chose ten typical eco-industrial parks in China and around the world and compared the degree of network connectedness of these systems that resulted from exchanges of products, byproducts, and wastes. By analyzing the density and nodal degree, we determined the relative power and status of the nodes in these networks, as well as other structural attributes such as the core-periphery structure and the degree of sub-network connectedness. The results reveal the operational problems created by the structure of the industrial networks and provide a basis for improving the degree of completeness, thereby increasing their potential for sustainable development and enriching the methods available for the study of industrial symbiosis.

Urban and industrial Metabolism： Towards Sustainable Planning

Journal of Civil Engineering and Architecture 2012年第2期6卷 182-188页

作者： Ma Carmen Ruiz Puente Elena Romero Arozamena INGEPRO Research Group Department of Transport and Technology of Projects and Process University of Cantabria Spain

Nowadays, urban planning supposes a key issue to promote sustainable cities＇ development. In the last decades, the urban growth of developed countries has caused several environmental, social and economic problems, such as the inefficient use of resources and infrastructures. Notwithstanding, detailed analysis of population＇s necessities allows decreasing these drawbacks. These enhancements can foster a more feasible development through technical sustainability criteria. Therefore, the urban metabolism study becomes an essential tool to plan a suitable management for material and energy flows. industrial ecology （IE） theory looks for the sustainable integration of human activities on their natural environment. It seeks mimic natural systems performance and their processes. industrial Metabolism （IM） studies those processes which turns material and energy into products and wastes. The IE final goals aim to promote improvements in process efficiency, decreasing consumption and waste generation through flows recirculation and exchange networks of material and energy. This contribution proposes a new conceptual framework which integrates urban and industrial metabolisms as an opportunity to achieve more efficient and sustainable development. The review of national and international experiences shows the improvements achieved through metabolisms＇ combination based on the exchanges of residual energy and water streams.

Focus on the key problems and dilemmas that arise in developing eco-industrial parks in China

Journal of Environmental Science and Engineering 2009年第3期3卷 43-55,63页

Despite the widespread incorporation of sustainable development into policy discourses, actually achieving the win-win-win scenario of economic, environmental and social development continues to be problematic. Advocates of industrial ecology suggest that shifting the basis of industrial production from a linear to a closed loop system, these gains can be achieved. In recent years, concepts drawn from industrial ecology have been used to plan and develop eeo-industrial parks （EIPs） that seek to increase business competitiveness, reduce waste and pollution, create jobs and improve working conditions. Despite a growing interest in EIPs, there have been few empirically informed studies that seek to explore the potential contribution such EIPs may make to sustainable development. This paper contributes to a developing sympathetic critique of industrial ecology by focusing on the key problems and dilemmas that arise in the course of developing eco-industrial parks, drawing upon empirical work conducted in China. The paper draws upon both an extensive survey of EIPs and in-depth interviews conducted with a range of stakeholders at some sites in China. As the paper reveals, EIPs in China are in their early stages and likewise their contribution to economic development and environmental policy, let alone social policies, is complicated and inchoate. The empirical material reveals that key features of industrial ecology such as inter-firm networking and collaboration in the form of materials interchange and energycascading are either absent or in the early planning stages. In each of the cases studied what is emerging is a form of EIP partly determined by the geographic setting and broader economic realities of the locality. While collaborative behavior between firms is central to EIP development if the potential benefits of industrial ecology are to be realized, it is important to realize that such behavior is difficult to develop from scratch through policy intervention.
