After the latter half of 1990s, non-regular employment has increased remarkably. It is the reason that each firm reduces the cost of labor and survives in the days of great competition. The main purpose of this paper is to examine the influence on the economic growth, which comes from replacing regular employment with non-regular employment. The wage differential between regular workers and non-regular workers is remarkable. Therefore, consumer confidence of regular workers, who do not lose their job, will deteriorate when the reduction of regular employment is performed. While regular employment has been reduced, long time regular workers have increased. It seems that this tendency will continue in future. Working for a long time decreases consumer demand on mainly leisure time. As the above-mentioned reasons, it is thought that the regular workers average propensity to consume (RW-APC) declines. The degree of decline of RW-APC affects the economic growth rate. If replacing regular employment with non-regular employment does not decline RW-APC that much, the economic growth rate rises. The reason is that the addition of non-regular workers by regular employment reduction increases consumer demand of economy. However, the growth rate comes to fall if RW-APC comes to decline ahead of a certain level. And the economic growth rate falls more greatly, if the degree of decline of RW-APC becomes bigger. In addition, wage increase of non-regular workers raises the economic growth rate and it increases regular and non-regular employment. This can also raise the real wage of both workers. In this way, wage increase of non-regular workers improves employment environment.
