A Study On Development Trace Of Contract-issuing Price

The construction contract-issuing price management which related the national construction fund the reasonable use, but also related the maintenance construction market the order as well as the protection forwards the package of bilateral legitimate rights and interests, is Country Concerned Department responsible for the work and the building all partners all extreme issue of concern. But constructs contract-issuing's changing was closed to the national economy development and the state economy organizational reform. The rule that construction contract-issuing price the development also is an extremely important question in the contract-issuing price management. But there is the flaw at present about this aspect research. In view of this, this article carried on the developing history of the construction project contract-issuing price research. It will fill the blank which take the construction contract-issuing price as the historical development process analysis.Firstly, this paper studied the construction contract-issuing price composition and the determination method development and the evolution in our country; Then analyzed influent factors of the construction contract-issuing price in different historical periods and explored two most important factors influencing the contract price: labor cost and the material expense; Next, carried on the statistical analysis of the contract price historical data, discussed the relations between the change of elements of the production and the change of the contract-issuing price, analyzed the reason why the changes of the labor unit price and the mechanical unit price both are too lower than the change of the contract-issuing price and pointed out the state that they are not suitable for the contract-issuing price and concerned measures. Furthermore, the author analyzed the developing trend of the bidding price ignoring the inflation. Based on this, according to the relationship between the contract-issuing price and its influent factors, this paper established the BP neural network to establish the model which can forecast the developing trend of the contract-issuing price. Moreover, taking Xi'an city as the example, we apply this model to forecast the contract-issuing price price and testify the practicability and maneuverability of the model.Through the study on the developing history of the construction project contract-issuing price, this paper posted the developing rule and the relationship with its influencing factors, enriched and perfected the management theory of the construction project contract-issuing price in our country to some extent, and provided a empirical foundation of the reasonable confirmation, effective control and standardization of the construction cost. In addition, this paper has a definite reference value to prompt the innovation of our country's building product cost system, its meet to the international construction market, and the construction contract-issuing price development towards the scientific and healthy direction.
