Remanufacturing in China is still in its early stage and faces pressures from society, policy, technology and management. Considering the actual states of remanufacturing in China, this paper researched several key management issues which were cared by various aspects from angle of view of remanufacturing players. Based on need analysis on trend of development of remanufacturing in China, six key management problems were mainly researched, and they were: risk management of remanufacturing players, remanufacturing production mana gement, remanufacturing quality management, authentication mode of remanufacturing in China, subsidy policy of remanufacturing industry, and performance assessment of remanufacturing. The characteristics of six issues were analyzed and the corresponding countermeasures were put forward.
In light of the sensitive and vulnerable environment, and high-toxic, high-acid gas reserves in the northeast area of Sichuan Province, the Project upheld the guideline of environmental first and implemented a construction model featuring energy conservation, environmental protection, eco friendly and low carbon emission. It combined the concept of systemic optimization and technological innovation, incorporated strict supervision into clean production, and promoted the innovation and application of energy conservation and environmental protection technologies throughout the entire process, ranging from optimal design, clean production to environmental supervision. Thanks to the above measures, the Project put an end to large-scale accidents caused by environmental pollution or ecological damages; minimized the negative effects on original eco-environment and local cultural and historical assets, and reached the standards of pollutant concentration, aggregation and environmental quality. As a result, the Project fulfilled its social commitments of making Sichuan-East gas transmission project an eco-friendly project, the Puguang gas field a “Green Gas Field”, and the pipeline a green energy corridor.

At last the paper introduced the innovative application in productivity of this idea, put forward the concept of decision making quality of farmers and explained the organization policies of agriculture of our country.
China is standing in a key period of accelerating transformation of its economic growth model. As the demand of energy is continuously growing, the pressure of environmental protection and climate change increasingly restrain China's sustainable economic and social development. The characteristics of the primary energy mix determine the power supply pattern in China, which is dominant with coal fired power generation. Coal fired power generation is a big consumer of coal and water and also a big contributor to pollutants. The strategic adjustment of the electric power industry is to optimize coal fired power development and transit to intensive and environment friendly development mode. This paper demonstrates the strategy of clean coal power technology in China, reviews the R & D achievements and industrial commercialization of ultra super critical technology and large scale air cooling technology, and expounds the supporting role of these two advanced coal fired power generation technologies in transforming the electric power industry.
With the era of financial crisis in international markets and domestic real estate industry policy adjustments, the large construction enterprises in which railway is the main business are now facing a lot of pressure. In this paper, the analysis of the difficulties and challenges in current construction enterprises is given, and the suggestion of building the advanced management concepts and methods of operation are proposed. Furthermore, the paper discusses about the changing operation mode of railway construction enterprise by the example of China Tiesiju Civil Engineering Group.
The new project management principle of implementing the total control in large, interdisciplinary, cross-industries and cross-regions systems to promote the transformation of the economic development way in the adjustment of industrial structure and the drive of science and technology innovation etc. was presented and discussed.

Mega project belongs to complex systems category and its overly complex system structure results in more management difficult. In order to improve management efficiency and complete project target, it is proposed to use new concept to identify and streamline size, scope and elements of mega project system, which is called effective large-scale system. Firstly, the concept of large-scale system and its effectiveness sources are defined. And then, the elements’ contribution degree and correlation degree criteria are presented. The contribution and correlation degree are based on fuzzy relationship matrix. Finally, coordination problems between the elements are solved by domination cooperative game model.
With the development of society, the engineering industry has become very complex, so the traditional construction contract can not meet the requirement of increasingly diversified development of enginee-ring. Therefore, through wide study and discussion, the Institution of Civil Engineers (ICE) agreed to improve the construction contract. In 1993, the new engineering contract (NEC) was launched by ICE to encourage the “team spirit” and establish a good partnership. After nearly 20 years of application, it was proved very effective. In 2009, the Hong Kong Special Administrative Region Government introduced NEC tentatively. The experience of the first project using NEC was introduced in the paper. The project results show that the NEC can save the duration and cost, reduce the contract disputes and increase effectiveness, which enhances the confidence of the engineering industry for introducing NEC.
One of the most important problems in safety management of metro construction is the insufficient collection and usage of construction safety information, so that the safety control of metro construction is still “in the black box”. Therefore, the presented research applies information technology to safety control of metro construction, which includes: a. For safety risk identification before construction, we proposed a novel approach to automatically identify construction safety risk out of engineering drawings with information technology. Then the safety knowledge of metro construction could be accumulating, sharing and reusing more accurate and effective. b. For risk early-warning during construction, we brought up an approach based on safety risk information fusion and temporal-spatial coupling for metro construction, which is able to effectively identify and track dangerous construction process and locations dynamically. c. For special sections of high risk, we developed the integrated control techniques of automatic monitoring and real-time early-warning for metro construction. The system send any early-warning information to construction workers on site, so that controlling methods and emergency moves can be applied in real time to ensure construction safety. The research achievements are successfully applied in the metro construction in Wuhan, Shenyang, Kunming, Zhengzhou, etc. in China.
