ish a market pricebased price formation mechanism, the price of the decision in the hands of the parties involved in the market, and ultimately the allocation of resources through the market in order to realize through the market mechanism to decide on project cost. This will standardize the construction marketpetitive behavior and the promotion of project bidding mechanisms play an important role in innovation. It can be said that the implementation of the project bill of quantities is a project cost management system in our country a big step forward, but also in China39。s macro regulation and control, enterprise autonomy offer, the market will price principle, to implement the implementation specification bill of quantity.
