The Influences of Population Age Structure＇s Changes on the Export Commodity Structure

For a long time, China has large population, so the labor-intensive products become the comparative advantage.This paper analyzes the influences of population age structure＇s changes on the export commodity structure of our country and draws conclusions.

China’s Imports Technology Structure and Its Relationship with Trade Partners:1995-2011

This paper uses the latest data to analyze the historical patterns and the current situation of the technology structure of China＇ commodities imports, the structure of China＇s commodities imports from 19 countries and regions, and China＇s interdependent relationship with its trade partners on the basis of studying 230 kinds of manufactured products categorized by their technological intensity. The results show that during the period of 1995-2011, the share of low technology （low-tech） products and medium technology （medium-tech） products declined,＂ the share of primary products, resource- based products, and high technology （high-tech） products increased; high-tech products had taken the largest share, bypassing low-tech and medium-tech products, as early as 2000; different types of countries exported different kinds of commodities to China and had different positions in China＇s imports; China had relatively high interdependent relations with Japan, South Korea and China＇s Taiwan; China had relatively low interdependent relations with the United States, Germany, France and the Netherlands; China＇s import dependence on major developing countries and emerging developing countries was less than these countries＇ export dependence on China; China was the leading export destination for major developing countries and emerging developing countries. Generally speaking, the development of China＇s import trade is inclusive, and China shares its growth with other countries. It not only promotes developing countries＇exports but also enhances developed countries＇ exports.

The Structure of China＇s Imports： A New Framework

Using the elbow function method to determine the number of classification groups of goods and applying the K-means algorithm to classify technical goods, this paper constructs a scientific classification framework of commodity structure and then measures the changes in China ＂s import commodity structure. It is found, first, that from 2000 to 2012, the import commodity structure in China underwent structural change. Shares of non-agricultural primary products and high-technology products increased sigmficantly, whereas shares of low-medium-technology products and medium-high-technology products declined. Second, from 2000 to 2006, the overall technology level of China＇s imports declined, but then increased from 2007 to 2012. Therefore, the Chinese Government shouM increase the share of high-technology and extra- high-technology products in total imports to stimulate structural transformation in manufacturing industries to make full use of foreign advanced technology and to prevent stepping into a low-end import commodity structure.
