萨伊定律与凯恩斯革命——经济学视阈下的供给侧改革

The Say's Law and the Keynesian Revolution——The Supply-Side Reform from the Perspective of Economics

萨伊定律和凯恩斯主义都是为了解决经济供求失衡而存在,它们的政策主张在不同的经济环境下具有不同的价值。对解决我国当前面临着"双过剩"的困境,凯恩斯主义所主张的需求侧政策只能起到有限的作用。要想根本性促进我国经济不断向更高的供求均衡演进,立足于供给侧改革才是长久之计。其中的创新发展是根本之道,去产能则是短期的必要手段。

Both Say＇s Law and Keynesianism exist to solve the imbalance of economic supply and demand. Their policies represent different values in various economic settings. To solve the plight of double surplus faced by China, the demand-side policies advocated by Keynesianism can only play a limited role. On that account, stand on the supply-side reform is a long-term solution, in order to fundamentally evolve China＇s economy to a higher equilibrium of supply and demand. In particular, innovation-based development is the fundamental and reducing of production capacity is a necessary means in a short-term.
