工程投资难以控制有多方面原因 ,工程计价方法混乱是其主要原因之一。本文通过对现行工程计价方式的分析 ,得出现行工程计价方法不利于工程投资控制的结论。提出两点改进计价方式的建议 :采用实物计价法确定工程造价 ;将工程产品也视为商品 ,让商家根据价值规律及市场供求关系来为工程产品定价。 Project investment is difficult to control for many reasons, the project pricing method is one of the main reasons. Based on the analysis of the present project pricing method, this paper concludes that the current project pricing method is not conducive to project investment control. Put forward two suggestions to improve the pricing method: the physical pricing method to determine the project cost; the engineering products are also considered as commodities, so that businesses based on the law of value and market supply and demand for the pricing of engineering products.
