政府采购是国家进行宏观经济调控的主要手段。选取2000—2008年美国政府采购规模与国内生产总值数据作为样本，建立政府采购规模与国内生产总值（GDP）的回归方程，研究政府采购规模与宏观经济增长之间的关系。研究表明，美国政府采购支出对宏观经济增长的贡献既有凯恩斯学派的“乘数”效应，又有古典经济学派的“挤出”效应，其调节效果由各级政府采购支出规模决定；选取政府采购支出占国内生产总值的比重和政府采购支出占政府财政支出的比重两个指标，对中国与美国政府采购的规模进行评估与比较，得出结论，中国政府采购距离适度规模还存在一个较长的持续增长过程，由货物类和服务类组成的经常性支出方面的采购比重有待进一步提升。

Government procurement is a country’s key method of macroeconomic control .Taking the 2000—2008 U .S .government procurement scale and the GDP data ,a regression equation of govern‐ment procurement scale and GDP is established with the finding that U .S .government procurement expenditure’ s contribution to the macro‐economic grow th has both the multiplier effect of the Keynesian School and the crowding‐out effect of classical economics ,which is determined by the scale of government procurement expenditure at different levels .Taking two important indexes—the pro‐portion of government procurement expenditure to GDP and the proportion of government procure‐ment expenditure to government fiscal expenditure ,and comparing government procurement scale of China with that of U .S .A .,the conclusion is that it still takes time before China government pro‐curement expenditure to reach a proper scale ,with the proportion of goods and service procurement expenditure to be increased .
