Simulation of the Mechanism between Construction Industry and Building Materials Industry and Its Influence Degree

On the basal idea of Input-Output mode,the interior mechanism and dynamical model between construction industry and building materials industry was proposed with System Dynamics.Collecting and analyzing the history data of construction industry,building materials industry and macro-economy,the current situation and tendency of construction industry and building materials industry were monitored with the dynamical model.Computing the parameters of the dynamical model on the situation of Financial Crisis 2008,the influence degree of construction industry and building materials industry was analyzed.The pulling effect of construction industry and building materials industry by the countermeasure of increasing 3 trillion of investment plans was also investigated.The research results indicate that the interior mechanism between construction industry and building materials industry is very obvious,and increasing investment plans is an effective method to expand domestic demand to promote economic growth of construction industry,building materials industry,even other related industries.
