摘　　要：传统的"三驾马车"说,从经济学视角,确认拉动GDP的三项因素是国内消费、国内投资和净出口。但是从经济统计视角,以其为基础测度净出口对GDP的拉动贡献却导致负效应悖论。本文将全球价值链概念融入经济统计测度,将GDP恒等式重新解释为国内最终消费需求、国内投资需求和国外需求,并使用国际投入产出表数据对新释三因素的拉动贡献进行测算,从而提出经济新常态下开发国外需求的建议。From an economics perspective,the traditional'troika'doctrine believes that domestic consumption,domestic investment and net export are the three factors contributing to GDP.But it is found that net export may lead to a paradox of negative effect,when it is used to measure contribution to GDP.By introducing the concept of global value chain into economic measurement,this article re-defines the GDP equation with domestic final consumption demand,domestic investment demand and demand abroad,and re-calculates the contribution of three factors using the new explanation and based on the International Input-Output Table.Finally,it provides suggestions on how to develop demand abroad at the Chinese economy enters the stage of new economic normal.

关 键 词：三驾马车 净出口 国外需求 贡献率 拉动系数
