卡尔多-凡登法则的新近争议考察

Recent Controversies over the Kaldor-Verdoorn Law

卡尔多-凡登法则揭示了需求和产出增长对技术进步的长期驱动效应,与之相关的两个问题近来引发争议:(1)此法则能够从新古典总量生产函数中推导出来,它在经验考察上的成功是否也归因于背后存在着一个核算恒等式?(2)当供给侧的因素对增长构成约束时,卡尔多-凡登法则是否失效?本文发现,凡登与卡尔多关于此法则的不同思想,影响着后来的研究和争论;从经验考察中得到的卡尔多-凡登法则,并不是国民收入核算恒等式的转化形式;一个涵纳"生产的社会关系"的Sylos-Labini模型拓展形式,为供给侧和需求侧的结合式考察提供了一种可能性。

The Kaldor-Verdoorn law, which explains the long-term driving effect of demand and output growth on technical progress, has recently been debated on two issues:(1) This law can be derived from the neoclassical aggregate production function, does the success of its empirical research also be attributed to an underlying accounting identity?(2) When supply-side factors pose constraints on growth, does the Kaldor-Verdoorn law become invalid? This paper finds that the different ideas of Verdoorn and Kaldor on this law influence later researches and debates;the Kaldor-Verdoorn law obtained from empirical studies is not a transformed form of the national income accounting identity;an extended form of the Sylos-Labini model with "social relations of production" provides a possibility for the combination of supply-side and demand-side investigation.
