However, China now faces a number of environmental degradation problems, in part, caused by her past agricultural reforms. In this paper we estimate, using a provincial-based panel dataset, a third-order translog cost function for China's grain production sector...
Stable carbon isotope ratios were determined for the OC and EC fractions of PM 2.5 collected from 14 Chinese cities in January and June/July of 2003. The period-averaged isotope values (δ 13 C) varied from −26.90‰ to −23.08‰ for OC and −26.63‰ to −23.27‰ for EC. A strong correlation (R 2 =0.70, p<0.0001) between δ 13 C OC and δ 13 C EC was...
