摘　　要：对我国食品制造业2004～2010年季度固定资产投资增量与行业主营业务利润率变动值进行了格兰杰因果检验,并建立了联立方程模型。结果显示,食品制造业固定资产投资增量变化主要受主营业务利润率变动值的当期值和前第5期值影响。By making a Granger casualty test and establishing the simultaneous equation model between the two variables of fixed assets investment increment and main business profit margin fluctuation in China food manufacturing industry from 2004 to 2010,the results show that the former variable value is mainly influenced by the previous fifth period value and the present value of the latter variable.
