Research On Dynamic Evolution Of The Foreign Trade Structure And Its Contribution To Economic Growth

At the age of information, International trade which was based on the results of deepening division of labor has become an important source of economic development with the rapid development of transaction technology and the greatly reduction of transaction costs. Under the conditions of scarce resources, a country should choose an appropriate trade structure to realize the optimal economic growth path. Because of the difference of intensity of production factors, the level of technological progress, market organization and the economic scale, The countries which participate in international trade can form their absolute advantages, comparative advantages, competitive advantages and the advantages of scale economy resulting from the expanding market capacity. Therefore, the countries should make the best use of their advantages mentioned above to participate in international trade. In addition, economic development will promote continuous updating of technique, enlargement of the production scale, optimization of the market organization and the dynamic evolution of the relative intensity of production factors. Therefore, their absolute advantages, comparative advantages and competitive advantages are on a dynamic evolution. What's more, the dynamic evolution of the trade structure is the inevitable result of economic development and competition.In the Chapter 2, the author put forth the analysis method of foreign trade structure from the view of revealed technological value-added (RTV) of trade goods: Firstly, we figure out the observation value of RTV according to the statistical data, Secondly, we calculate the Optimization estimate value of RTV based on sample observation value of RTV, Finally, we can establish indexes of quantitative analysis of trade structure based on RTV of trade goods. In the Chapter 3, the author provided theoretical basis for the dynamic evolution of trade structure, built the basic model of the dynamic evolution of trade structure and analyzed the path and characteristics of the dynamic evolution of trade structure from the view of ultra-marginal and marginal analysis. The path and characteristics of the dynamic evolution of trade structure depend on specialization economy and the size of the transaction efficiency coefficient. In the Chapter4, the author analyzed the factors and path that foreign trade structure contributes to economic growth in theory and build an empirical model on the basis of decomposing foreign trade structure.Finally, the author empirically analyzed the basic characteristics and the path of the dynamic evolution of China's foreign trade structure and their contributions to China's economic growth. We can come to a conclusion: The foreign trade structure of China's export products are on a dynamic evolution from low technology value-added to high technology value-added, which is contrary to the foreign trade structure of China's import products. However, the coefficient of foreign trade structure of China's export products is located at a middle level and forms a binary foreign trade structure of the coexistence of low-tech value-added and high-tech value-added. As to the foreign trade structure's contribution to economic growth, export and import are both playing an important role in economic growth. Generally speaking, the contribution of export products to economic growth lies in low technology value-added products and medium low technology value-added products, while high technology value-added products occupy a larger share than that of low technology value-added products in import products.
