This article constructs Stochastic Frontier Production function model and analyzes the technical efficiency of tobacco production on the base of panel data with out-input of 17 major tobacco producing areas from 1998-2007. Furthermore, we discuss the efficiency differences of different time, regions and their convergence. The result shows that the technical efficiency of tobacco production fluctuates with time at random and different regions display a marked difference. At the same time, if on the view of the whole country, the tobacco producing efficiency difference of ev...
