The game and mathematical analysis of this model indicates that the exceeding price can be averted by giving the right of allocation to the underwriter,the aim of underpricing level achieved and the efficiency of inquiry realized.

Based on the fact that the relation-table is a suitable data structure with a large amount of data storage,good query efficiency and operating function,a data model including the relationship table and the tree for storing XML documents is proposed.

Efficiency Assessment of Local Public Expenditure:A Two-Step DEA Model with Non-Discretionary Inputs

A recyclable economy efficiency assessment is performed on an industrial area of its 15-year development with the above assessment theory and method.

By using Data Envelopment Analysis(DEA) method,the efficiency assessment index systems for emergency shelters under planning and operating are established with the construction cost and operation cost as the input indexes and service capabilities,accessibility and safety grade as the output indexes.

There are some problems and shortcomings in the present efficiency appraisal in that the appraisal indexes are not set up according to the types of production,low efficiency analysis is not quantitative,and information provided is not enough.
