The realized conditions of the construction industry supply chain synergy are put forward through the analysis of the construction industry vertical supply chain synergy using the method of evolutionary game (taking the construction suppliers and the general contractors for example). With the horizontal coordination problems in the construction market put forward, the synergetic mechanisms among the government, industry associations, market players and the rules of the market in the construction market are analyzed. The existed technology-economic system coordinated model is improved and the synergetic degree model of construction industry system itself is set up. The conclusion is drawn that the economic benefit indicators and technology indicators of Chinese construction industry system synergy low and the two must be synergized through the analysis of the synergetic degree of the economic benefit indicators and technology indicators of the construction industry system.

5对建筑业纵向供应链协同(以建筑供应商和总承包商为例)进行了演化博弈分析，提出了建筑业供应链协同的实现条件；分析了建筑市场中政府、行业协会、市场主体、市场规则之间的协同机制；对已有的科技——经济系统协调模型进行改进，形成了建筑业系统本身的协同度模型，并对建筑业系统的经济效益和科技指标的协同度进行分析，得出我国目前建筑业系统的经济效益指标和科技指标的协同度低，必须协同二者之间的关系。
