Heteroscedasticity space stochastic frontier model and technical efficiency estimation based on cold chain logistics

Fu-Bin Pan

Introduced the effect of the stochastic frontier analysis framework, respectively, paragraphs consider random disturbance and technical inefficiency and both exist homoscedastic, build normal - in the form of truncated normal distribution heteroblastic stochastic frontier model for logistics management, makes a research on the homoscedastic normal - truncated gaussian model production technical parameters and the influence of technical efficiency estimation, which estimates parameters by using the method of maximum likelihood, and concluded that the technical efficiency estimates.
