The paper puts forward new ideas for the establishment of distributed price monitoring system on based on the Multi-Agent theory, in order to make the price monitoring process intelligent, the fault diagnosis of real-time price intelligent and conflict resolution intelligent. Price monitoring intelligent system based on Multi-Agent, which realize the intelligent operation, control and supervision of prices, can improve the decision of the whole control system, and improve the quality of the price data. The intelligent system not only provides the technical support for the price monitoring in China, but also explores a feasible technique approach for the Multi-Agent theory.

With the advent of information age, E-government has become an objective need to improve administrative efficiency. And research on the input-output efficiency of E-government is not only responsible for taxpayers, but important to measure the role of E-government in promoting social development. In the analysis of E-government Cost of inputs, it is not comprehensive only to see the explicit cost. We should consider the hidden costs when implementing E-government, including costs of impersonal communication costs, loss of information, the network paralysis and network attacks, which are not only the challenge of Egovernment, but the challenges of the information age. Similarly, when analysis the output of E-government, not just think the improving administrative efficiency, but take account of the impact of the intangible sense of democracy training for citizens, re-shaping the structure of government, the convenience of administrative supervision, impetus to information industry and so on. On this basis, the paper constructs index system of Egovernment input-output efficiency to understand the entire effect of E-government development, also builds function to compute the efficiency. In the end the paper puts forward conclusions: it is biased to analyze the benefits of E-government neglecting the specific economic and social environment. We need to focus on the increase of impersonal costs and communication costs by E-government, also new injustice caused by the technical barriers. And the future development trend of E-government is a low-input and high efficiency.
