The growing environmental problems, the rapid urbanization, and the disappearance of the demographic dividend in China has brought unprecedented opportunities to the development of prefabricated housing (PH). However, many barriers are hindering the promotion of PH, for instance, cost, lack of regulations, and the shortage of knowledge, among which cost is identified as one of the most critical barriers. Unlike previous studies focused only on production costs, this research aims to investigate transaction costs (TCs), e.g., searching costs, negotiation costs, and enforcement costs. First, this paper develops a theoretical TCs framework of the PH supply chain, based on an extensive literature review. Secondly, an empirical study was conducted on two cases in Chongqing to validate the TCs framework. Key stakeholders are identified by Social Network Analysis (SNA). Subsequently, 25 semi-structured interviews were conducted with key stakeholders, both to verify the new TCs framework and to explore stakeholder concerns about TCs. The centrality metrics by SNA identified six key stakeholders who have a significant influence on TCs. It is found from the interviews that both the conceptual phase and the construction phase are stages where the majority of TCs occur. Both the developer and the general contractor are paying for more TCs compared to the other stakeholders. This study contributes to theory by initially introducing the concepts of TCs to the PH field, and the findings bring implications on the governance of PH supply chain to both private stakeholders and the government. • Transaction costs in the prefabricated housing supply chain cause low economic efficiency. • Critical stakeholders include developers, general contractors, architects, local governments, supervisors and component suppliers. • Developers and general contractors are recognized as bearing more Transaction Costs compared with the other stakeholders. • The conceptual phase and the construction phase are where the majority of transaction costs occur. • To improve the governance of projects, both public and private stakeholders can take actions to reduce transaction costs.

Sustainable construction projects affect various stakeholders with different social, environmental and economic interests. It is essential that the decision makers maintain effective communication with relevant groups to avoid project failures. Although citizen participation offers a means of better addressing and meeting stakeholder concerns and expectations, the decision/evaluations of contemporary sustainable projects are becoming ever more complicated, with an increasing number of stakeholders involved to actively defend their own interests. In response, this paper provides a thorough and comprehensive analysis of the stakeholders of sustainable construction in China and quantifies their influence in decision/evaluations by semi-structured interviews (in research stage I) and a three-round Delphi survey (in research stage II). Follow-up interviews (in research stage III) are carried out to collect more in-depth views concerning the characteristics and the respective importance of each stakeholder group involved. The findings indicate that the government is the most influential entity and the extent to which its intervention is needed in balancing the interests of other stakeholders presents a major challenge. The high potential influence of end-users is also identified, suggesting the need for a more transparent and inclusive participatory decision/evaluation process in the country. An enhanced future role for NGOs is further identified. [ABSTRACT FROM AUTHOR]

Rapid urbanization poses a significant challenge of accommodating the poor, particularly in developing countries such as China where affordable housing has only been initiated a few years ago and will continue to be developed in the coming years. Two major considerations in affordable housing programs are cost and time, as the ability to meet the needs of low-income households is the main target of these programs. However, it is not a common strategy to address affordable housing shortage by means of incorporating sustainability features. One of critical issues is the lack of sustainability framework to integrate sustainability in affordable housing. This paper aims to identify the key sustainability performance indicators (KSPIs) which are useful to guide the development of affordable housing. A preliminary list of 42 key sustainability performance indicators of affordable housing was identified through an extensive literature review. This was followed by a questionnaire survey to solicit the professional views from three stakeholder groups, namely government, developers and academics in the Chinese construction industry. Via the fuzzy set theory and variance analysis, 24 KSPIs were finally highlighted. These findings provide useful references for policy makers as well as industry practitioners to develop affordable housing programs in a sustainable manner. This helps to achieve the sustainable development at the regional scale. [ABSTRACT FROM AUTHOR]

Contaminated sites have caused worldwide attention and been dealt with through a variety of policies and practices both nationally and regionally. Unlike the US, Canada, Japan, and Europe, which have accumulated rich experiences in contaminated site management, China, facing serious contaminated site issues, still lacks effective strategies on issues such as remediation standards, funding resources, accountability, and stakeholders coordination. This paper collected policies for contaminated site management from 31 regions in China. A comprehensive analysis was conducted of current policies, including policy framework, number of policies and instruments, policy types, and spatial and temporal variation. We find that most regions in China, such as Beijing and Chongqing, have taken positive measures to manage contaminated sites, and that there are similarities as well as differences in policy responses and mechanisms in different regions. A multi-level objective system, combined with diverse instruments, cooperation between different stakeholders, and a multi-sectoral joint supervision mechanism emphasized by all 31 regions, are extremely important to promote sustainable site management. Specialized policies, site-specific standards, information disclosure, public participation, remediation priority and groundwater protection are urgently needed to strengthen the local framework of contaminated site management and to promote remediation projects.

Abstract: With the increasing environmental issues, now cleaner production has been implemented across all the regions of China. During this process, regional governments have played a leading role for promoting cleaner production. Main measures include coordinating the various stakeholders, providing financial support, stipulating appropriate policies and conducting capacity building programs. Such an innovative initiative is quite unique and should be further studied. This paper reflects such a perspective through a case study of Liaoning province. We first introduce the main initiatives for the promotion of cleaner production in Liaoning and then identify the key barriers. Our focus is to provide suggestions for future improvements. Finally we make our conclusions. [ABSTRACT FROM AUTHOR]
