By comparing the essential variable values of the competitive and the non-competitive auction market,how price fixing enterprises manipulate the permitting price by creating changes of permission demand is analysed in order to reduce the financial burden of pollution disposal.

This paper introduces the categories of ancient texts data, expounds the literature value, historical value, aesthetic value and collection value of the ancient texts data, and analyzes the situation of auction market of ancient texts data.

The article for one of the cases in users,the transaction between one to one user,the profit game of both sides in the transaction are studied by means of the mutual auction and .

Double auction mechanism is brought into Ad Hoc networks and two distinct cooperation incentive mechanisms based on double auction are proposed in the article.

Considering dynamic,heterogeneous and autonomous characteristics of computing resources in the computational grid environment and the flexibility and effectivity of economics methods applied to solve the problem of resource management,a modified double auction method for resource allocation on computational grids is presented.

Under the requirements of user quality of services and by using economic leverage of double auction,autonomous Agents compete with each other for resource usage,so that resource management for grid is autonomously adapted to changes in the en-viron.
