Recently, international trading is facing a developing situation which presents as the increase of freedom and protection along with the existence of competition and monopolization. The trend of integration, globalization and internalization is now constantly building up. Although free competition and trading are the results which counties and international organization expect, because of the fierce international competition, companies and governments try to establish monopolistic company of international competence by using the power of their own country, which leads to the increase of protection. With the rising of new international trading theory put forward in 1980s, this problem has won wide concern from international trading theory experts and thus strategic trading theory comes up. The theory breaks up the assumption of complete competition in classical trading theory, puts forward incomplete competition and increasing returns to scale, brings new idea to the study of international trading area.Based on the others' study and by means of conjectural variations and calibration, the paper constructs quantitative model of strategic trading policy, showing demonstration study of strategic trading policy.The paper chooses car manufacturing in China to analyze the effect of our country's strategic trading policy. There are two reasons: firstly, car industry is our country's leading industry, involving many departments, whose development directly related to the promotion of comprehensive national strength of China and the stable increase of civil welfare. Secondly, the car industry of China which was protected by the government before, is now facing a big challenge because of the promise of slashing taxes of exporting cars made when entered WTO and needs new policy to support.The paper is devided into five chapters. The first chapter covers the background and meaning of this topic, the literature review, research thought and method. The second chapter explains the theory, involving strategic trading policy theory, restricted condition of the policy implement as well as appraise of the policy. The third part constructs the strategic trading policy quantitative model of car manufacturing in China. The forth part which is the core of the paper, based on the data of car manufacturing in 2002, tries to analyze strategic trading policy by examples, carries through dynamic effect simulation of the long term policy of car manufacturing by comparison of the effects of different policy implement and gives suggestions of related policies. The fifth part is the conclusion. |
