建筑业产业定位与工程价值变化周期

在由工程项目实施期和从事施工建造活动双重限制所定义的建筑业发展空间内，建筑业实现效率和效益提升的路径狭窄。以建设项目的工程价值变化周期为基本依托，从广义建筑业和广义建设项目生命周期概念出发，构造建筑业新的发展空间，在工程建设项目的价值规划、价值形成、价值实现、价值消失诸过程中寻求以工程功能发挥价值最大化为导向、以建筑业附加价值最大化为着眼点的建筑业新增长路径，拓展事业组合，是建筑业增长的重要突破点。

The Life-cycle for Construction Project Value and Economic Growth to Construction Industry in China

The traditional space for construction industry development is limited both to the implement stage of construction project and the build-up activities. There is a narrow way, which is to elevate the efficiency and benefit for construction industry, in that scope. Based on the generalized life-cycle of construction project and the generalized construction industry, new developing space for the industry is built-up by taking the advantage of cycle of construction project value. There is a project value chain made of value planning, value taking, value giving and value vanishing in the space. Along the chain, the maximization of the function value of construction project, which is aimed at the maximization of the added value to construction industry, is used for leading. Business combination for construction industry will be developed, and the critical access for economic growth to the industry will also be found out.
