The paper begins with a discussion of issues of cross-sectional dependence, and introduces the concepts of weak and strong cross-sectional dependence. Then, the main attention is primarily paid to spatial and factor approaches for modeling cross-sectional dependence for both linear and nonlinear （nonparametric and semiparametric） panel data models. Finally, we conclude with some speculations on future research directions.展开更多

Therefore, energy-efficient technologies become an active research area motivated by energy necessity and environmental concerns. With energy-efficient technologies, a number of epoch-making technical approaches can be expected. Energy efficiency technologies are affecting all forms of energy conversion and all aspects of life.展开更多
