Technical innovation strategy is the policy which the enterprise carries out for technology innovation in a long term. The paper took the practice of the technology innovation strategy in Petro China Changqing Oilfield Company as a case study, and illustrated the significance, function and features of the self-developed technology innovation, cooperation development technology innovation and introduction-innovation based on the strategy structure of the energy enterprises. The suggestions for technology innovation strategy structure for large energy enterprise were proposed in the paper.展开更多

While the proportion of high-efficient energy and renewable energy is still low. Improving rural household energy sustainability can meet economic,environmental and social needs in the overall development context of northern China. Many barriers have obstructed the rapid sustainable development of rural household energy in terms of financial,political and technical aspects. Based on relational research and case study,the paper provides guiding of rural household energy sustainability improvement in northern China from energy efficient improvement,renewable energy use and improving equitable distribution,affordability and accessibility of sustainable energy.展开更多
