Modeling of the impact of the financial crisis and China's accession to WTO on China's exports to Germany

We focus on discussing the impact of China's accession to WTO and the financial crisis on China's exports to Germany, particularly in agricultural products, based on some most recent proposals. Firstly, structural breaks caused by those events are detected. Then the Box–Cox model and a new tree-form Constant Market Share (CMS) model are fitted to discover the long-term impact of those events on the trade relationship between China and Germany and the growth causes of China's exports to Germany. We found that China's accession to WTO had a negative short-term impact on China's exports and its market share in agricultural products, but a positive short-term impact on its market share in industrial products and a positive long-term impact on its exports and market share in both classes. The tree-form CMS model shows the growth of China's exports to Germany due to competitiveness after this event was much higher than before. The financial crisis exhibited a negative short-term impact on China's exports to Germany, but a positive short-term impact on China's market share and the trade relationship between both countries in industrial products. China's market share in agricultural products was not affected by the financial crisis.
