Study on generation and development of production frontier theory;

Single-side support vector regression model for parametric production frontier analysis;

The approaches to evaluating DEA efficient DMUs(Decision Making Units) based on production frontier are studied.

In the paper, the theory of production frontiers and its non-parametric measurement ac Proaches are used to figure out the input compressing productivity index, Malmquist productivity index based on the input oriented non-parametric production frontiers.

Regarding water resources as one of the elements of production,the efficient production frontier is built based on the DEA relative efficiency evaluation with C_2GS_2 model of output oriented.

Regarding water resources as one of the elements of production,the efficient production frontier is built based on the DEA relative efficiency evaluation with C~2GS~2 model and C~2R model of output oriented.

Regarding water resources as one of the elements of production,the efficient production frontier is built based on the DEA relative efficiency evaluation with C2GS2 model of output oriented.

The theoretical frontier of ideological and political work refers to the latest development and tendency of theoretical research on ideological and political work,including mainly the latest develop- ment and tendency of the academic system,theoretical system,theoretical form,theoretical model,de- velopment and focal arguments.
