Comparative study of commercial building energy-efficiency retrofit policies in four pilot cities in China
The energy efficiency of existing commercial buildings is more challenging to regulate and improve than the energy efficiency of new constructions. In 2011 and 2012, the Chinese Government selected four cities- Shanghai, Tianjin, Shenzhen, and Chongqing- to implement pilot commercial building energy efficiency retrofit program. Based on site surveys and expert interviews in these pilot cities, this research conducted a comparative analysis on incentive policies of local city level. The analysis results show that policy designs of existing commercial buildings should be further improved. The aspects that influence the implementation effect in the future, such as subsidy level, installments, and business model promotion, should be specified in the policy clauses. Referring to the technical solution and cost-benefit in Chongqing, we found that lighting system is the most common retrofit objects while envelope system is the least common one. And the subsidy incentive is greatest for educational buildings, followed by office buildings. In the end, we further discussed the problems and obstacles in commercial building retrofit market, and provided a series of recommendations
Agricultural information dissemination using ICTs: a review and analysis of information dissemination models in China
Open Access funded by China Agricultural UniversityOver the last three decades, China’s agriculture sector has been transformed from the traditional to modern practice through the effective deployment of Information and Communication Technologies (ICTs). Information processing and dissemination have played a critical role in this transformation process. Many studies in relation to agriculture information services have been conducted in China, but few of them have attempted to provide a comprehensive review and analysis of different information dissemination models and their applications. This paper aims to review and identify the ICT based information dissemination models in China and to share the knowledge and experience in applying emerging ICTs in disseminating agriculture information to farmers and farm communities to improve productivity and economic, social and environmental sustainability. The paper reviews and analyzes the development stages of China’s agricultural information dissemination systems and different mechanisms for agricultural information service development and operations. Seven ICT-based information dissemination models are identified and discussed. Success cases are presented. The findings provide a useful direction for researchers and practitioners in developing future ICT based information dissemination systems. It is hoped that this paper will also help other developing countries to learn from China’s experience and best practice in their endeavor of applying emerging ICTs in agriculture information dissemination and knowledge transfer

Assessing the effects of technological progress on energy efficiency in the construction industry: A case of China
Energy-saving technologies in buildings have received great attention from energy efficiency researchers in the construction sector. Traditional research tends to focus on the energy used during building operation and in construction materials production, but it usually neglects the energy consumed in the building construction process. Very few studies have explored the impacts of technological progress on energy efficiency in the construction industry. This paper presents a model of the building construction process based on Cobb-Douglas production function. The model estimates the effects of technological progress on energy efficiency with the objective to examine the role that technological progress plays in energy savings in China's construction industry. The modeling results indicated that technological progress improved energy efficiency by an average of 7.1% per year from 1997 to 2014. Furthermore, three main technological progress factors (the efficiency of machinery and equipment, the proportion change of the energy structure, and research and development investment) were selected to analyze their effects on energy efficiency improvement. These positive effects were verified, and results show the effects of first two factors are significant. Finally, recommendations for promoting energy efficiency in the construction industry are proposed
The state of the art in e-business: A case study from the Chinese construction industry
In the 21st century, e-business is seen as the new frontier. Currently e-business has been widely used in other industry and to some extent in global construction market, particularly in developed countries, such as UK, EU and USA. Evidence of performance and success stories shows that the implementation of e-business is already delivering high improvement and innovation in construction project planning, design, delivery and management. However, the current performance of e-business in the emerging market, such as India and China is limited. China, as the world’s second largest economy after the United States, has the world fastest growing economy, averaging 10% growth of the past 30 years. The domestic construction industry is booming in both infrastructure and building construction sectors. It is predicted that nearly half of the world’s new building construction will be in China by 2015. In a similar way to other countries, there is a great potential for China to implement e-business in the construction industry in order to improve its productivity and competitiveness. This paper initially explains the concept of e-Business and its impacts in construction industry and reviews the development of Chinese construction industry over last two decades. A case study of one of the largest Chinese construction IT Companies is carried out to further analyse benefits, challenges and the market potential of e-business in China. This study provides a better and deeper understanding of the different characteristics of the implementation and capability of e-business in Chinese construction industry
Livelihoods and Migrants' Social Protection: An Investigation of Migration and Health in Beijing and Tianjin, North China
This paper contributes to a growing body of research on the social protection for rural-urban migrants in Chinese cities. Drawing on extensive fieldwork in Beijing and Tianjin and applying an analytical framework of livelihood studies, it examines an important aspect of migrants‟ social protection, namely migrants‟ health, in particular workplace safety and occupational health. It aims at (1) delineating the current state of affairs in respect of social protection for rural migrants; (2) identifying the risks and threats to migrants‟ health as perceived by the actors involved; (3) examining the extent to which the social rights of rural migrants are recognized, and the struggles that migrants have fought for securing livelihood and realising such rights; and (4) assessing the central and local government responses to the challenges posed for mobile livelihoods and suggesting possible ways forward
Health Biotechnology Innovation for Social Sustainability -A Perspective from China
China is not only becoming a significant player in the production of high-tech products, but also an increasingly important contributor of ideas and influence in the global knowledge economy. This paper identifies the promises and the pathologies of the biotech innovation system from the perspective of social sustainability in China, looking at the governance of the system and beyond. Based on The STEPS Centre’s ‘Innovation, Sustainability, Development: A New Manifesto’, a ‘3D’ approach has been adopted, bringing together social, technological and policy dynamics, and focusing on the directions of biotechnological innovation, the distribution of its benefits, costs and risks and the diversity of innovations evolving within it and alongside it
Evaluation of management strategies for the operation of high-speed railways in China
High-Speed Train (HST) operations have recently been introduced in rail passenger transportation markets worldwide. Although the technologies for such operations have levelled at speeds of around 300 km/h, the operating parameters to be adopted in each application will differ from country to country. The operating environment will be one of the crucial success factors for the implementation of HST operations in China. This paper compares three different management/ownership models which might be used in China. The paper analyzes the characteristics of each model and proposes an optimal plan of an operational system to develop HST operations in China by using a hierarchy goals achievement matrix approach
Chinese hydropower companies and environmental norms in countries of the global South: the involvement of Sinohydro in Ghana’s Bui Dam
The paper examines the role of environmental norms in Chinese overseas investment in hydropower dams, exemplified by Sinohydro’s involvement in the Bui Dam in Ghana. While the investment of Western companies in hydropower dams in the global South is decreasing owing to changing notions of sustainability in the West, the investment of Chinese companies in hydro dams in Africa, Southeast Asia and Latin America is accelerating at great speed. The emergence of Chinese companies in international markets in the context of China’s Going Abroad strategy has sparked a debate on whether China can be considered a norm-changer in international development. The paper considers this question in the context of the status of environmental norms in Sinohydro’s investment in Ghana’s Bui Dam. The paper argues that the role of international norms in Chinese investment is dependent on two factors: the contractual arrangements under which Chinese companies operate abroad and the political institutions of host countries
