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

Export trade not only drives China＇s economic growth, promotes industrial upgrading and technological progress, but also may have a negative impact on the environment. After reviewing and summarizing the existing relevant literatures, tire paper collects the required statistic data from 2003 to 2006 and uses the panel data model to measure the environmental effects of export trade in the Yangtze River Delta. The results show that the export trade of Yangtze River Delta has a negative impact on the environment. When the variables of economic scale, economic structure areftxed, with the export trade growth of 1%, the industrial sulfur dioxide emission and industrial waste water emtsston will increase by 0.12% and 0.23% respectively.
