Abstract: The development of economy in a country depends on both of its external and internal economic cycles. Based on economic development theory, new economic growth theory and the concrete condition of China, this paper proposes E/I Economic Cycles Theory and a Model of E/I Economic Cycles. With a deep analysis of combination and interaction of the external and internal economic cycles in China based on this model, this paper advocates maximizing the positive effect and minimizing the negative effect of the two mutually-complementary cycles, through proper adjustment and motivation, so as to promote sustainable development of economy in China.
