| With the deepening of integration of the world economy, the pattern of world production changes deeply, the traditional division of labor in the industrial pattern is gradually replaced by a new pattern of International Fragmantation.In the system of International Fragmantation, the product of the production chain is configured in different countries and regions.Only under International Fragmantation-a new framework.to study China’s trade structure upgrade.we can recognize the fundamental upgrade path of its trade structure in international trade.And based on this recognize,fand the way to upgrade China’s trade structure, and the future direction of proposed recommendations, which has important theoretical significance and practical value of China’s foreign trade development.Based on an extension of the two-stage model framework, this article introduce Cobb-Douglas production function into the model to derive the comparative advantage of the dynamic changes, and analysis International Fragmantation"s effect on trade patterns and dynamic effects, draw the impact of changes in the path.First of all,through the degree of International Fragmantation based on HS Code, trade competitiveness index, revealed comparative advantage index, technological added value index of trade structure, describe the change of the actual situation in China from from two levels of overall and industrial. Secondly, based on a simple econometric analysis, this article verify the positive effect of International Fragmantation on the net exports, revealed comparative advantage, export technical content, as well as to promote the role of the technical content of the import trade structure than inhibition.China should focus on achieving comparative advantage of dynamic transformation, strengthening enterprise-led division of elements, choosing the introduction of foreign capital, establishing a moderate trade protection system to promote China’s trade structure upgrade. |
