Regression analysis of relationship between fixed asset investment and waste water discharge reduction in textile industry

The correlation between the fixed asset investment of the textile industry and the wastewater discharge reduction intensity was analyzed using the regression analysis theory.It was found that the asymptotic regression functional relation was fit for the relationship between the fixed asset investment and the index of wastewater discharge reduction intensity based on the maximum coefficient of determination(R-Square) in regression curve fitting.From the curve,increasing the fixed asset investment increases the intensity index of wastewater discharge reduction.However,the intensity index will not increase infinitely,and it will gradually become stable.The trend has close ties with the implementation of cleaner production by enterprises by controlling pollution at the source and during processing,which not only saves natural energies and reduces costs,but protects our environment.From social and economic standpoints,it makes significant sense.
