利润不仅是经济增长的主导因素,而且有自身的运行规律。利润周期的规律在于: (1) 利润增长总是不断出现周期性波动,与科技进步和产业发展的周期性规律同步,与经济的景气循环周期相一致。 (2) 利润周期波动与GDP周期波动同步,但波幅更大,这一点无论在发达国家还是发展中国家几乎都得到了一致 Profit is not only the dominant factor of economic growth, but also has its own operating rules. The law of the profit cycle lies in: (1) The profit growth always appears cyclical fluctuations, which are synchronized with the periodic laws of technological progress and industrial development and are consistent with the economic cycle of the economy. (2) The volatility of the profit cycle is synchronized with the volatility of the GDP cycle, but the volatility is even greater, which is almost the same in both developed and developing countries
