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

摘要

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.
