本文在制造业产品价格逐年攀升的经济背景下,利用固定效应变系数面板数据模型研究2002年至2009年制造业28个行业劳动力成本和以要素替代为表征的技术进步对工业品价格造成的不同影响,并验证这种作用关系的长期稳定性。实证结果表明,以要素替代为表征的技术进步在一定程度上延缓了制造业产品价格上涨,但作用的绝对幅度弱于人均劳动力成本上升和通货膨胀带来的影响,并且工业品价格与技术进步和劳动力成本表现出长期稳定的协整关系。
This paper studies the labor cost of 28 industries in manufacturing from 2002 to 2009 and the difference in the prices of industrial products caused by the technological progress characterized by factor substitution from the economic background of the year-by-year rise of manufacturing product prices. Influence, and verify the long-term stability of this relationship. The empirical results show that the technological progress characterized by factor substitution has slowed the price rise of manufacturing products to some extent, but the absolute magnitude of the effect is weaker than the increase in per capital labor cost and inflation, and the industrial product price and technological progress And labor costs showed long-term stable co-integration relationship.
