Experience at home and abroad tells us that in the process of economic development in one country, it is definitely mistaken and very harmful to us if we adopt the dual economy models that ignore agriculture. In the process of industrialization in one country, it is a great strategic issue to correctly weigh and grasp the status and function of agriculture in social economy. Therefore, we should establish the view of modern agricultural system and two-center epistemology, namely, agriculture is the foundation of all societies and meanwhile it is also the eternal pillar industry of national economy. Agriculture cannot be replaced by any other industries.
