Study of Fertility Rate Based on Endogenous Growth Theory

Based on the cost-utility theory, this article tries to build a model of endogenous economic growth of population to indicate that economic development has an impact upon population fertility. By analyzing the result of the numerical simulation of the model, the article finds that, in the stabilized state, there exists an inverted-U'shaped relationship between the economic development and the population fertility. The result of the empirical test, to some extent, proves of the correctness of the theoretical analysis.
