以“三驾马车”为主动力的增长模式曾经带给中国经济长时期的快速增长,但是随着近年来国际经济环境的持续恶化,中国经济下行压力陡增。以投资、出口、消费为主要内容的传统经济增长模式对经济增长的贡献率日渐下降。本文从宏观经济学的角度论述了供给侧改革对中国经济战略性调整的必要性。 The “three troika” -based growth model once brought a long-term rapid economic growth in China. However, with the continuous deterioration of the international economic environment in recent years, the downward pressure on China’s economy has risen sharply. The contribution rate of traditional economic growth mode with investment, export and consumption as the main content to economic growth is decreasing day by day. This paper discusses the necessity of the supply-side reform to the strategic adjustment of China’s economy from the macroeconomic point of view.
