【正文】 n possibility Structure for the development of our country at this stage is basically the section, block segmentation, various corporate entities are responsible for the project owners, in accordance with the administrative relationship to accept its superior department in charge of oversight. In order to address corporate units of each project the professionalism of problems in the bidding phase of the introduction of the tender agent system, the construction phase to employ the munity supervision and mandatory to accept government supervision. From a practical point of view, the construction market problems are mostly bud at the bidding stage, the tender agent system introduced and did not achieve the project bidding process, implement the Three Excellencies principle. The reason is the institutional issues. The existing institutionbuilding, project legal sense, not the nature of the legal person, it is at all levels of government (public finance) and an agent, they have the legal flexibility to provide space for the performance of official duties (select bidding, qualification review, evaluation, calibration), the only moral constraints, to guide their decisionmaking by service agencies. Economics, there is the assumption that rational people, when they can very small risks (institutional design to give him the power law provides a flexible space) to obtain a larger return on their personal interests, the moral force and bees fragile. In practice there is the leadership of nonintervention, intervention projects officer handling the owners of nonintervention, intervention in the situation of the tender agent, realistically speak for themselves. Building Products features easy to act as operation carrier In theory, works as a futures modities, the quality characteristic of the expected needs of those who caused the uncertainty of product quality concerns, and thus demand for modities, persons (tender person) is more concerned about the modity producers (bidders) in credit, performance and credibility. In reality, the main layers of agents in the project legal cases, the construction of goods to the agent of this property rentseeking provides a good pretext. General Building Products (mainly referring to design changes) while technical content is not high, but because a large number of contracts, the list of projects, project implementation and settlement has a certain degree of flexibility, and project cost control and greater flexibility in handling the accounts, there are black profits space, this space provides the project bidding secret operatio ns material basis. Thus formed on the construction market at the macro situation of excessive petition, and in the micro demand for modities, who have the inherent power to exclude petition. From domestic to foreign public works projects, both the existence of such tendencies. Credit management is still a small social infrastructure Our country is in building a socialist market economy, the initial stage, although the market economy in the entire social life of the dominant, but because of the results of the economic role of longterm plans and traditional culture dictates, the people in their daily activities are still heartfelt emotion in power. Although the building products involved in each and every people, but it is not like home appliances, people will be free to purchase and supervise the exercise of the powers, leading home appliance industry must operate in good faith based, its credibility, in order to gain market share. The real purchasing power of building products concentrated in a few hands (the tender, agents, evaluation mittee of experts). As the bidding for construction products and process certain elements of the need for confidentiality, objectivity, causing the nonease of munity supervision, and a decrease of bidders because of false information leading to the tender risk of failure. In addition, an enterprise because of false information in a project bid fails, do not regard as in the West have been developed market economies, as the expulsion by the market, so bidders to provide false information to participate in the bidding intensified the phenomenon. Relying on physical construction market, the use of existing information technology is perfectly capable of bidders information accurate and prehensive nuclear trial, but because of local protectionism, national unified information platform for integration lags behind the reality of the regulatory needs, but also to the black box operation to provide opportunities. Of the main parties to the transaction have not yet bee essentially independent of the market players Under the current system has been analyzed above, the project owner is a legal sense, only the subject, in essence, only the agent of the Government at all levels. The project owner39。 ④ tenders are now a large difference in size of projects the professional great. For most projects, the agency cost considerations from the pressed tender, evaluation time, only a few hours, in such a short period of time required produce highquality evaluation results of evaluation experts, impractical, often only to fulfill the legal only a procedure. Based on the above analysis, we present evaluation of the bidding activities of the Commission to act as a rubber stamp function, or evaluation experts to participate in secret operations, specific for a particular issue there will be an objective judge of the phenomenon of understanding. Construction bidding black and white contract prevailed At present in our project bidding, the construction unit with the unit or the tendering agency tender plicity, making up false bidding, Ming Zhao dark setting, the signing of black and white contract issue has been outstanding. In the fifth meeting of the Tenth National Pe
