技术变革、利润率与中国经济增长——基于马克思经济增长模型

Technological Change,Rate of Profit and China’s Economic Growth-Based on the Marxist Economic Growth Model

基于马克思资本积累理论的逻辑构建经济增长模型,论证技术变动和收入分配通过利润率对经济增长的重要影响。在此基础上,使用中国经济数据,估算相关劳动价值论指标,并通过回归分析验证以上理论。研究发现,有机构成提高导致利润率下降是中国前一个阶段经济增长放缓的重要因素。而通过市场与政府有机结合,提高技术创新效率,可以实现劳动收入份额提高的同时,维持利润率水平和持续经济增长。这是社会主义市场经济发展的必然方向。

Based on Marxian theory of capital accumulation,this paper constructs an economic growth model and demonstrates the important influence of technology change and income distribution on economic growth through profit rate.Using the data of China’s national economy,this paper calculates the relevant indicators of labor theory of value,and verifies the theory through regression analysis.Based on the decomposition of the rate of change of profit rate,we find that the decline of profit rate caused by the rising organic composition is an important factor for the slowdown of China’s economic growth in the previous stage.Combined with Marx’s theory of technological change,this paper points out that through the organic combination of market and government,improving the efficiency of technological innovation,increasing the share of labor income,maintaining a certain level of profit margin and sustained economic growth is the inevitable direction of the development of socialist market economy.
