The knowledge-based economy analyzes economic organization and development when the creation, distribution and use of knowledge become decisive factors. To become a successful knowledge economies, countries must act simultaneously on their education base, their innovation systems and their...

In this paper, by using an augmented Lagrangian approach, we obtain several sufficient conditions for the existence of augmented Lagrange multipliers of a cone constrained optimization problem in Banach spaces, where the corresponding augmenting function is assumed to have a valley at zero....

The effects of phosphorus (P)-based nutrient management plans on economic and environmental risks of dairy and dairy-poultry farms in Virginia were evaluated. Phosphorus-based nutrient management plans can greatly reduce P runoff risk but also reduce farmers' returns. P-based plans cause greater...

It is critical to alleviate problems of energy and air pollutants emissions in the metropolis because these areas serve as economic engines and have large and dense populations. Drivers of fossil fuel use and air pollutants emissions were analyzed in metropolis of Beijing during 1997–2010. The...

China has proposed its 2020 clean energy target together with the climate change target of reducing CO2 intensity of the economy by 40–45% below the 2005 level. This article investigates the feasibility of these targets by testing their consistency under possible economic development...

The decline of China's energy intensity slowed since 2000. During 2002–2005 it actually increased, reversing the long-term trend. Therefore, it is important to identify drivers of the fluctuation of energy intensity. We use input–output structural decomposition analysis to investigate the...

This study examines the annual CO2 emissions embodied in China's exports from 2002 to 2008 using environmental input–output analysis. Four driving forces, including emission intensity, economic production structure, export composition, and total export volume, are compared for their...

This research studies the low carbon transition of the electric power sector in China using a multi-level perspective (MLP) of niches, socio-technical regime, and landscape, as well as literature on innovation systems. Three lines of thought on transition process are integrated in the paper to...
