求翻译：随着改革的深化，投资主体向多元化发展。工程造价管理关系到投资主体和承包商的经济利益，关系到整个市场的竞争规范化，建筑业劳动生产率的逐步提高以及全社会的科技水平的进步等一系列问题。目前我国的建筑工程造价管理远远落后于建筑业的快速发展形势，工程造价管理体系中存在的许多深层次的问题严重制约着建筑业的发展。因此其改革理所当然成为建筑业改革的核心问题。要从根本上管理和控制住工程造价，必须克服对特定阶段的偏重，对项目投资实施全过程进行控制，从组织、技术、经济、合同与信息等方面挖掘潜力，有效地控制造价和科学地管理造价确保工程质量、不断降低工程成本。重视技经人员的培养，提高他们的专业技术和业务素质。广泛应用计算机进行预算操作，使预算工作科学化、标准化、规范化，提高工作效率和预算的审核质量。通过实践经验，我认为有效控制工程造价的核心是：以人为本，抓住招投标、合同签订、合同执行、预算审核四个环节是什么意思？

With the deepening of reforms, diversification of investment subject to. Engineering cost management related to the economic interests of the investors and contractors, on the standardization of competition in the market as a whole, gradually increasing of labour productivity in the construction industry and technology progress of society as a series of issues. Current construction cost management in China lags far behind the rapid development of the situation in the construction industry, construction cost management system, many deep-seated problems in serious constraints to development in the construction industry. So the core of its reform course construction reform issues. To radically the management and control of project cost, must overcome biased to a particular phase, to control the whole process of project implementation, from the Organization, contracts, technology, economy and information, and other potential, effectively control the cost and scientific management ensure engineering quality, lowering the cost of cost. Importance to the skill and training of personnel, improve their professional skills and professional quality. Widely used computer budget operations, budget scientific work, standardization, standardization, improve efficiency and quality of budget audit. Through practical experience, I think the core of effective control of project cost is: people-oriented, seize the bidding, contract signed, contract execution, budget audit four links
