The influencing measurement study of symbiotic environment on the logistics enterprises' profit

Abstract

Regarding the symbiotic environment as the special resource for the logistics enterprises, this paper proposes the residual differential method to measure the effect that the symbiotic environment acts upon the growth of the logistics enterprises' profit. The core thought is that symbiotic environment is the main factor that causes the fluctuation of the growth of the logistics enterprises' profit. Through the quantification of these fluctuations, the reflecting scales are gained that the symbiotic environment acts upon the logistics enterprises. This method first analyzes the various symbiotic environments of different enterprises, and respectively calculates the Solow residual of different enterprises in the corresponding symbiotic environments, then gains the unbiased estimator of population mean of residuals. So the difference value between logistics enterprise residual and this unbiased estimator is the measuring value that the symbiotic environment acts upon the profit of logistics enterprises.
