Embracing off-site innovation in construction in China to enhance a sustainable built environment in urban housing

With the rapid rate of urbanization and pressing need for higher levels of sustainable development within the built environment in China, the housing construction industry presently is facing urgency of shaping a sustainable construction process. This paper examines several sustainability challenges from the large-scale urban housing construction, and explores the connection between off-site innovation and sustainability within a context of China's housing construction industry. The study also identifies four pillars of strategy agendas that could enhance an enabling innovation environment for the ultimate goal of sustainability: (1) institutional environment, (2) public housing market, (3) organisational actions and (4) technological capacity. The knowledge and research findings presented in this paper would provide a ground framework that helps evaluate and assess the significances of off-site innovation to assist with a sustainable built environment.

Addressing sustainable challenges in China

Purpose

– The purpose of this paper is to present an innovative approach to addressing increasing sustainable challenges facing China's built environment which are linked to a diverse range of factors including rapid economic and population growth. The research context includes mass urbanisation in and the Chinese construction industry's attitude towards adopting sustainable construction processes. The focus is placed on examining current on-site construction practices in China which have historically remained largely unchanged; this includes a high reliance on cheap labour accompanied by a substantial material waste. An alternative approach is to increase the uptake of off-site production in China's residential construction industry, however no previous studies have investigated the potential advantages and barriers of this alternative approach.

Design/methodology/approach

– In collaboration with an industry organisation a survey was completed by 110 construction professionals in China. The questionnaire referred to 21 individual factors relating to their perception about the current and potential future uptake of off-site production in construction processes in China.

Findings

– The results confirmed the existing level of off-site production in China's urban residential construction industry was relatively low. At present the cast-in-situ method was considered by stakeholders as the most effective approach. The findings also confirmed the benefits of off-site production are not fully understood by the housing construction industry in China. It is argued this knowledge gap reduces the Chinese construction industry's motivation levels when seeking to embrace the off-site production approach and adopt improved sustainable construction practices.

Originality/value

– This is an original study designed to address a gap in knowledge as there has been no previous research conducted into the use of off-site industrialised process in China. The results provide a valuable insight into the uptake of off-site production in the residential construction industry and will assist stakeholders and policymakers to increase the level of sustainability.

Marketization and perceptions of social protection in China's cities

One of the major challenges for China's ongoing economic reforms is how best to handle the social protection needs of its citizens in the face of mounting insecurities resulting from the marketization process. We first argue that China has adopted a middle road in its approach to balancing marketization and stability. We then proceed to draw on a large survey of people living in China's cities to examine how successful China's middle road has been perceived to be through the eyes of its urban populace. Our findings support the view that the market and state are complements and that fostering sustained economic growth requires sound social protection arrangements. © 2005 Elsevier Ltd.

Migrants as Homo economicus : explaining the emerging phenomenon of a shortage of migrant labor in China's coastal provinces

The problem of a shortage of migrant labor is a new development in China's coastal provinces. We discuss the reasons for this emerging phenomenon using a conceptual framework that extends the traditional Lewis dualistic labor market model to incorporate a migrant labor market. We emphasize that migrant labor shortage in China not only reflects a declining wage gap between what peasants receive and what migrants can earn in the cities, but also the institutional legacies of the planning era such as the hukou (household registration) system which discriminates against migrants vis-a-vis urban residents in terms of access to social insurance and other social services. We proceed to draw on a unique survey of migrants and urban residents collected in Jiangsu to show that migrants receive lower incomes, and they have poorer access to social insurance than those with an urban registration in China's cities. Our findings have important implications for the alleviation of the migrant labor shortage problem.

Contractual thinking and responsible government in China : a constructivist framework for analysis

Responsible government is often seen as contingent on democracy. Yet despite China's continued lack of notable progress in democratization, recent years have witnessed some limited moves towards responsible governance. In the absence of free elections and other institutional arrangements, how can an authoritarian regime become responsible? This paper turns to the role of ideas and culture in general and contractual thinking in particular for an explanation. Contractual thinking, defined as a particular kind of intersubjective understanding between the government and citizens with regard to their mutual interests, is present in both China's contemporary official discourse on "responsible government" and traditional Chinese culture. Taking a constructivist approach, the paper focuses on two interrelated aspects of the role of contractual thinking in the construction of responsible government. First, it examines how contractual thinking, by helping redefine the identity and interest of the government in line with citizens' loyalty, could allow more responsible government behaviour. It then illustrates that in the case of government irresponsibility, contractual thinking sets the discursive context for rightful resistance from citizens as well as for a more sympathetic reading of such resistance by the government, both of which, the paper argues, could facilitate the development of responsible governance.

Economic growth with coal, oil and renewable energy consumption in China: prospects for fuel substitution

We examine the relationship between Chinese aggregate production and consumption of three main energy commodities: coal, oil and renewable energy. Both autoregressive distributed lag (ARDL) and vector error correction modeling (VECM) show that Chinese growth is led by all three energy sources. Economic growth also causes coal, oil and renewables consumption, but with negative own-price effects for coal and oil and a strong possibility of fuel substitution through positive cross-price effects. The results further show coal consumption causing pollution, while renewable energy consumption reduces emissions. No significant causation on emissions is found for oil. Hence, making coal both absolutely and relatively expensive compared to oil and renewable energy encourages shifting from coal to oil and renewable energy, thereby improving economic and environmental sustainability.
