文摘The paper conducts an experimental study on the relation between the distribution of the emission of pollutant of Nanjing City and the scale, composition and technical level of the industry. The paper also tries to apply the Kuznets’ Curve in environmental field.
文摘We examine the dynamic relation between returns,volume,and volatility of our futures markets.The results show that there exists a positive correlation between absolute returns and volume,but no correlation between returns and volume; Granger causality demonstrate that no causality relation exists between returns (or absolute returns) and volume,except copper’s absolute returns causes volume;the conditional volatility of returns has no direct impact to futures returns; copper’ and soybean’ trading volume contributes strong explanatory power to volatility,but aluminous’ trading volume has no direct impact to volatility.
