[Method] The grain trade gravity model was constructed and the main influence factors of the grain trade flow were analyzed, such as GDP, population, grain yield, CO2 and air temperature. [Result] GDP had negative correlation with China’s grain trade volume; carbon dioxide emissions had significantly positive correlation with China’s grain trade volume. [Conclusion] China’s grain structure of varieties should be adjusted with changes of people’s grain consumption structure; the better institutional arrangements should be created during grain production and distribution to reduce carbon dioxide emissions.展开更多

The paper analyzes China’s soybean production capability and discovers that the present yield of China’s soybean plant system cannot satisfy the domestic demand.The paperalso provides the method to solve such matters by using the result of a modified Cobb-Douglas model. In the third section of this paper, the impacts of GMO regulation on soybean trade and marketin China are analyzed.In this section,we provide a methodological issue to analyze the impacts of such regulation on trade.The paper then explains the implicated result induced by such regulations.展开更多

However, existing literature has not given adequate attention to this issue. Our paper develops a theoretical model to explain the mechanisms whereby changes in the grain surplus constrain the level of urbanization in a closed economy context and the grain trade affects the level of urbanization by acting on the grain surplus in an open economy context. A test of the theoretical model applied to some developing countries in Asia during the period 1993-2010 shows that international trade is generally negatively correlated with level of urbanization. However, cereal and non-cereal trade vary in terms of their relation to urbanization： whereas the former is positively correlated with level of urbanization, thelatter is negatively correlated with it. Since the net import of cereals relaxes the constraint imposed on the level of urbanization by the domestic grain surplus, it can have a marked positive effect on the course of urbanization. Our research findings show that provided grain production or grain security is guaranteed, developing countries may adopt a policy of importing an appropriate amount of grain to increase their level of urbanization.展开更多

文摘A grain surplus and the grain trade are closely related to the urbanization of developing countries. However, existing literature has not given adequate attention to this issue. Our paper develops a theoretical model to explain the mechanisms whereby changes in the grain surplus constrain the level of urbanization in a closed economy context and the grain trade affects the level of urbanization by acting on the grain surplus in an open economy context. A test of the theoretical model applied to some developing countries in Asia during the period 1993-2010 shows that international trade is generally negatively correlated with level of urbanization. However, cereal and non-cereal trade vary in terms of their relation to urbanization： whereas the former is positively correlated with level of urbanization, thelatter is negatively correlated with it. Since the net import of cereals relaxes the constraint imposed on the level of urbanization by the domestic grain surplus, it can have a marked positive effect on the course of urbanization. Our research findings show that provided grain production or grain security is guaranteed, developing countries may adopt a policy of importing an appropriate amount of grain to increase their level of urbanization.
