摘要
罗默定理是置盐定理的重要拓展。本文指出罗默定理仅适用于部门整体技术变迁,如果引入部门内部的异质性资本与技术扩散过程,即使实物工资不变,由资本有机构成提高所推动的利润率下降依然可以出现。只要掌握新技术的高效率资本能够在一定时期内获得超额利润,即使在该技术普及后利润率下降,其仍有动机选择新技术进行生产。基于中国2001至2014年的经验研究发现,罗默定理并不能解释全部情况,一些年份发生了"马克思偏向型技术变迁",进而不足以否定马克思的科学论断。
Roemer’s theorem is an important extension of Okishio’s theorem.This paper notes that Roemer’s theorem is only applicable to general technological changes in sections.If heterogeneous capitalist and technological diffusion processes are introduced within sections,even if real wages remain unchanged,a decrease in the profit rate driven by the increase in the organic composition of capital can still occur.As long as the high-efficiency capitalists who have mastered the new technology can make unusual profits within a certain period of time,even if the popularisation of the technology leads to a decrease in the profit rate,they still have an incentive when it comes to choosing the new technology for production.Based on China’s empirical research between 2001 and 2014,it is found that Roemer’s theorem cannot explain the situation in its entirety,and"Marx-biased technical change"has been occurring for some years,hence the denial of the Marxian scientific thesis is not enough.
