An Improved Grey Multivariable Verhulst Model for Predicting CO_2 Emissions in China

摘要

A new method for discussing the relationship between CO_2 emissions and bilateral FD1 is proposed using grey systems theory. CO_2 emissions and bilateral FDI, GDP are separately regarded as the input to, and output of, a grey system to establish a grey multivariable Verhulst model, GVM(1,N). To improve the prediction accuracy, the residual modification model are combined to the original GVM(1,N) model. Based on data relating to CO_2 emissions and bilateral FDI, GDP in China from 2001 to 2014, empirical research shows that the bilateral FDI help reduce CO_2 emissions, whereas the GDP results in CO_2 emissions.
