It is important to forecast the oil supply capacity due to its scarcity and non-renewability. This paper attempts to forecast and analyze thirty-five current and potential net oil-exporting countries. Integrating both qualitative and quantitative methods, the oil production and consumption are predicted based on historical data, so that the world net oil-exporting capacity can be obtained. The results show that the ＂roof effect＂ of the world net oil-exporting capacity may appear before 2030. Unconventional oil will play an important role in the future world oil market. The competition and cooperation relationships between OPEC and non-OPEC will last for a long time.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, the 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 are fixed, with the export trade growth of 1%, the industrial sulfur dioxide emission and industrial waste water emission will increase by 0.12% and 0.23% respectively. So we must pay serious attention to the negative effects, and promote regional sus tainable development rapidly through adjusting the export structure and strengthening environmental regulations.展开更多

Our findings suggest that the interaction between selection effect and competition effect ultimately causes actual firm markup to be higher than the baseline markup by 7.11%. Exporting firms' actual markup is higher than the baseline markup by different degrees. In terms of the decomposition of selection effect, TFP explains for 28.05% of selection effect, and nonproductivity factors explain for the rest 71.95%. By controlling for the type of firms' export,the export-productivity paradox only exists for processing trade firms, which shows that with increasing trade facilitation, the policy incentives to encourage firms to export are major contributors to the low export markups.展开更多
