英文文献：Environmental Regulation And Implications For U.S. Pork Exports
英文文献作者：Metcalfe, Mark R.
英文文献摘要：
Environmental concerns linked to hog production are growing in the United States and the European Union and therefore new regulations controlling animal manure management are being imposed to address these concerns. This study determines that potential increases in U.S. environmental regulation would have minimal effects on the relative competitiveness of U.S. pork exports, while much more stringent EU regulation has the potential to significantly impact EU competitiveness and contribute to continued increases in U.S. pork export quantities.
