Openness Degree of Agric Products, Self-sufficiency Rate of Agric Products and Growth Rate of Agric Output

摘要

This paper explored the mechanism of agricultural products opening. The research of the literature showed that the degree of openness of agric products has both direct and indirect influence on the self-sufficiency rate. An increase in the degree of openness of agric-products has a direct negative effect on its self-sufficiency rate. More so, this increase in the degree of openness also have a direct positive effect on the growth rate of agricultural output, and then has an indirect positive effect on the self-sufficiency rate of agric products. This paper used transformation and mathematical derivation of the distribution identities of agricultural products from both the static and dynamic perspective, and proved the mechanism relation derived by mathematical model relations. It helps for a better understanding of the relations elaborated in literature for the agric-products openness, the agric-products self-sufficiency rate and the agric-output growth rate, providing theoretical basis for empirical measurement.
