This paper first used the international market share and trade specialization coefficient to make a quantitative comparison of the competitiveness of the primary industries of China and South Korea. Then it measured the trade integration index and export product similarity index of China and South Korea. It is found that: although China and South Korea have a particular competitive relationship in the main industrial fields, the differences in their respective areas of strength are significant, and the two countries show a good complementarity of resources. Therefore, China and South Korea should abandon suspicion, strengthen mutual trust, further optimize the trade structure between the two countries, make use of the framework of the regional agreement of RCEP, support China and South Korean enterprises to jointly develop the third-party market, and maintain and consolidate China-South Korea relations to promote the long-term development of economic and trade cooperation between the two countries.

Integrated circuits are the cornerstone of the development of information and communication technology industries in various countries, and to a large extent affect the development of the future technological industry revolution, and are known as “industrial food”. With the transfer of the global integrated circuit industry chain, emerging economies in East Asia represented by China and South Korea occupy a core position in the global integrated circuit trade. In recent years, although the scale of China’s integrated circuit trade has expanded rapidly, it has been in an unbalanced state for a long time, and the trade deficit is extremely high. The domestic demand for high-end integrated circuits can only be met by imports. The development of my country’s integrated circuit trade is large but not strong. Thanks to the financial support and preferential policies of the Korean government, in the 1980s, Korean integrated circuit companies took the lead in breaking through the international technology of memory integrated circuits. After that, the Korean government developed other integrated circuit products on this basis. Export of foreign exchange earning products. In order to measure the gap between China’s IC trade international competitiveness and South Korea more accurately. Next, a literature study is conducted on the comparative analysis of the development status of integrated circuit trade between China and South Korea. It was found that the development of South Korea’s integrated circuit industry was later than that of China, but the latter came ahead.

The establishment of China-South Korea Free trade area has a positive role in promoting bilateral trade. By analyzing the current situation of China-South Korea trade, the features of China-South Korea Free trade agreement and using intra-industry trade index and other indicators, this article intuitively shows the impact of trade.

The research results show that: first, the gradual reduction of tariff barriers for agricultural products of China, Japan and Korea will have a greater trade effect on China; Second, the creation effect of China-south Korea trade is far greater than that of China and Japan. Third, the reduction of agricultural tariffs will promote the growth of the overall economic aggregate of the three countries and change the terms of trade.

The rising of E-business and network trade has promoted the transform and new development of international trade. Due to this, this paper attempts to investigate the impact of E-business on international trade between China and South Korea. On the grounds of rapid development of E-business, the E-business is regarded as a determinant that can impact the international trade between China and South Korea. Meanwhile, the quarterly data form the first quarter of 2000 to the fourth quarter of 2017 are employed to conduct an empirical analysis under the vector auto-regressive model. The international trade between China and South Korea is treated as an independent variable. The E-business, the foreign direct investment and the real exchange rate are treated as dependent variables. Furthermore, a menu of statistic approaches such as the Granger causality test and the vector auto-regressive estimates will be used to testify the impact of E-business on international trade between China and South Korea. Via the Granger causality test, the results report that the E-business is major reason that can drive the development of international trade between China and South Korea. Through the vector auto-regressive estimates, the results also report that the E-business has a positive effect on international trade between China and South Korea. Furthermore, this paper provides a view that the E-business is a kind of a determinant that can promote the international trade between China and South Korea. Therefore, the China’s government should pay much attention to the infrastructure of E-business so as to enlarge the trade volume between China and South Korea.
