Abstract: Through the inspection of the theory of excessive competition, we can see that the root of the error of it lies in the abandonment of the theory of labor value. On the one hand, it makes Brenner unable to correctly understand the law of the tendency of the rate of profit to fall, so he has to take competition as the starting point of analysis, reverse the relationship between the decline of profit rate and competition, and ignore the transformation of capitalism from free competition to monopoly, as well as the diversity of competition strategies among capitals in the monopoly stage. On the other hand, this makes the theory of excessive competition limited to the distribution level to find the reasons for the decline of profit rate, and ascribes the decline of general profit rate to the increase of real wages caused by excessive competition among capitals. The paradigm of its theoretical framework is from Adam Smith based on Ricardian, while the paradigm of its empirical analysis is from Adam Smith. The reason of the declining trend of profit rate lies in the relative decreasing trend of surplus value production, and the law of the tendency of the rate of profit to fall is its theoretical expression. The law of the tendency of the rate of profit to fall is rooted in the fact that capital depends on the exploitation of living labor, but the way of exploitation tries to reduce living labor to the minimum.
